Pigeon Wars

Pigeon Wars

For 10 days this August,a fresh-faced 41-year-old named Jeffrey Traill trolled Hollywood in his Honda, videotaping pigeons. Pigeons lined the ArcLight theaters near the Walk of Fame, commandeered the roof at Big Lots!, perched along power lines like stolid chess pieces. “Pigeons,” Traill says in his video, shakily framing one roost. “Pigeons,” he says again, wrenching his camera toward another. The effect is nauseating. “Over there,” he says. “Over there. Over there.”

Traill is one of a half-dozen neighborhood activists whose volunteer campaign against these birds has escalated idiosyncratically for more than a year. Their leader, Laura Dodson, had ordered him out on yet another round of surveillance, to update the group’s hulking pigeon “dossier.” “We’re kind of an unusual neighborhood association,” Dodson told me.

Dodson has lived in Hollywood for 29 years. She likes pigeons and does not want them killed or made to suffer. She said this repeatedly in the clipped, mildly truculent way she says a lot of things. But having helped muscle gangs and drugs out of her neighborhood in the 80’s, Dodson says she feels besieged again. She and her group, the Argyle Civic Association, have turned to a series of unconventional approaches to neutralize a problem they simply refuse to put up with. “We’re in the middle of the biggest boom, and there are pigeons everywhere — like where they’re going to put the W hotel,” she says, invoking, as she often does, the upscale hotel as a symbol of Hollywood’s hard-won renaissance. “There’s nothing but pigeon poop.”

A pigeon dispenses about 25 pounds of excrement a year. Often this gunk must be blasted off hard-to-reach places using boom lifts and steam hoses. Pigeon-related damage in America has been estimated to cost $1.1 billion a year. But the full scope of our disdain and distrust for the birds is impossible to quantify; it’s hard even to explain. Marketing by the bird-control industry — a lucrative offshoot of the $6.7-billion-a-year pest-control business — reminds us that pigeons and their dung can spread more than 60 diseases. This is true, but not necessarily panic-inducing, given the exceedingly rare incidences of respiratory infections like cryptococcosis.

For much of the 20th century, controlling pigeons primarily meant killing them. (Culling remains a common fallback position; the United States Department of Agriculture kills 60,000 pigeons a year in response to complaints.) But even the trade journal Pest Control now warns that with “millions of bird lovers out there,” you must consider “the publicity you would receive if your local paper runs photos of hundreds of poisoned pigeons flopping around on Main Street.” As we have become less tolerant of the birds, we have also, somehow, grown more concerned about their well-being.

The bird-control industry has evolved to fill this paradoxical niche. Pigeon control has increasingly become about moving pigeons elsewhere. With a staggering catalog of spikes, nets, sticky gels, coiled-wire barriers, ultrasonic noisemakers, holographic frighteners, fake owls and even electrified strips — from Bird-Shock Flex-Track to Bird Jolt FlatTrack — bird controllers have been busily transforming our bare ledges into unwelcoming obstacle courses. Often, according to Bob Van Gelder, who for 25 years has been president of the full-service pigeon-proofing company Birds Away/Pigeons Away, you must “follow the problem” — destabilizing pigeons’ existing roosts and anticipating their next move. “Birds have instinct,” he says. “We have logic.”

Of course, these displaced pigeons inevitably turn up somewhere else. The Argyle Civic Association sought a more holistic, area-wide fix — as well as a humane one. So in May of this year, after consulting with People for the Ethical Treatment of Animals, the group voted unanimously to implement a novel strategy pioneered by the Pigeon Control Advisory Service, or PiCAS, in Britain.

Essentially, the PiCAS model complements the widespread pigeon-proofing of buildings — this aimless shifting of pigeons from facade to facade — by situating large birdhouses, called dovecotes, in places like city parks. Displaced pigeons relocate inside. As the pigeons breed, volunteers and workers reach into the dovecotes and remove their eggs, replacing them with dummy eggs to stave off rebreeding. It’s a mechanical form of birth control that, PiCAS claims, can reduce total pigeon populations by half over four years.

As all kinds of wildlife rebound and infiltrate the cities from which we exiled them, PiCAS’s approach is among a number of humane and ecologically savvy efforts on the forefront of urban animal control. Elsewhere, the U.S.D.A. is working to orally vaccinate skunks and raccoons against rabies and to use chemical contraceptives to treat nuisance animals like deer, prairie dogs and Canada geese. As we learn to recognize each city as an ecosystem, we may be more willing to sustainably control these problematic populations as a wildlife manager might, rather than eradicating them or shooing them around as exterminators do.

Dovecotes have been erected in a handful of British towns, and when I first spoke to the director of PiCAS, Guy Merchant, in May, he told me that Melbourne, Australia, was finalizing an ambitious scheme in its financial district. Melbourne, Merchant said, agreed to take every recommendation in the 30-page report that he produced after an initial visit. (He offers free consulting outside Britain.) Since the number of pigeons is a function of the availability of food, Merchant ordered a public-relations campaign discouraging pigeon feeding and suggested the appointment of a municipal “pigeon warden” — a caseworker to persuade the most “deliberate and persistent” pigeon feeders to feed only around the dovecote. While in Melbourne, Merchant persuaded one elderly gentleman to do just this, once the dovecote was erected. Merchant deemed this “a major coup,” since the man, notorious for meting out about 90 pounds of seed every day, was probably supporting 3,000 pigeons all by himself.

But just as PiCAS’s dovecotes essentially domesticate pigeons, they also appear to bring these well-meaning pigeon lovers — often the lonely seniors we presume them to be — back into the fold as well. Around the dovecote, their eccentric hobbies is legitimized. “That feeder then becomes the Pied Piper of Hamelin,” Merchant told me. “He or she brings the pigeons with him. It’s one of those rare things in life — a win-win situation.”

I pictured an elegant, almost St. Francis-like pastoral. It wasn’t until I arrived in Hollywood that I began to wonder if this, or any harmonizing of avian instincts and human logic, could withstand one unfortunate fact: we have logic, but we do things every day to defy it.

The pigeons among us are feral — free-roaming descendants of once-domesticated birds. The pigeon was the first bird species domesticated by man, more than 5,000 years ago, in fact. Millions were raised across medieval England and France, either as messengers or meals, in dovecotes similar to the ones PiCAS employs. In the late 18th century, the French aristocracy’s pigeons, which were free to fly into the fields, were infuriating the peasantry, looting grain reserves and pecking at crops. The farmers weren’t permitted to kill them, and this incessant, aerial tyranny has been cited as one cause of the French Revolution. Once in power, the revolutionaries made a point of destroying the dovecotes, spilling the stocks into the wild — meaning that ever since, generations of these exiled nobles have fanned out to muck up the hoods of our cars.

Modern Americans have been similarly shortsighted. Pigeons were one of the few species left unprotected by the Migratory Bird Treaty Act of 1918. They were often killed with shotguns. After World War II, poisons emerged as discrete alternatives. Many, like the Rid-a-Bird Perch, which poisoned pigeons through their feet, were phased out as the environmental movement grew. Avitrol, which is typically mixed with corn or other grain, is the last remaining poison in commercial use.

Killing pigeons doesn’t actually accomplish much, however. In 1961, Basel, Switzerland, began rapaciously culling its population of 20,000 pigeons. Its trappers and marksmen depleted some flocks by 80 percent, only to watch them return, sometimes in greater numbers, within weeks. This went on, like a demoralizing carnival game, for 25 years. The city finally stood down, having killed 100,000 pigeons. There were still 20,000 pigeons in Basel.

Then, in 1988, the biologist Daniel Haag-Wackernagel established 13 lofts (essentially, rooftop dovecotes) around Basel and began replacing eggs. Within four and a half years, Basel Pigeon Action, as he called his program, reduced the city’s pigeon population to 10,000. He has subsequently become one of the world’s few experts on feral pigeons. Guy Merchant, the director of PiCAS, claims to have devised his organization’s strategy before Haag-Wackernagel’s work began and stresses that the two are not affiliated. Nonetheless, when PiCAS claims that the dovecote scheme is “scientifically proven” to halve pigeon populations, it is citing Haag-Wackernagel’s peer-reviewed 1995 study, “Regulation of the Street Pigeon in Basel” — and, notably, his study alone.

The futility of killing pigeons is a far better established fact. An emptied niche in any ecosystem will rapidly be filled, either by immigrants or newborns. And pigeons are not only opportunistic, keeping a keen lay of the land, but also prolific breeders. This is partly our fault. Millennia of domestication selected for more fecund pigeons long before these natural cliff-dwellers settled into the architectural canyons of the modern city. As the value of food cheapened after World War II, pigeons urbanized along with us, no longer having to commute to forage in surrounding fields. The city, with its abundance of safe and sheltered breeding locations, now also offered an abundance of food. “Whenever you couple that,” says Louis Lefebvre, a biologist at McGill University who has studied pigeons in Montreal, “you’ll get an explosion.”

Moreover, when someone feeds pigeons in the park every day at noon, the birds are able to organize their day around that appointment. There, pecking 145 times a minute, a pigeon can rapidly eat its fill for the day, about one ounce. Cobbling that sustenance together from trash might require thousands of pecks at numerous locations, many of them far apart. Haag-Wackernagel speculates that the resulting free time and excess energy allows pigeons to breed more rapidly and successfully. Feral pigeons lay eggs six times a year, producing as many as 12 squabs in that time.

“In a city like New York or like Melbourne,” Merchant argues, “the pigeon population is sustained solely by little old ladies and little old men that go out every single day and feed top-quality foods to the birds.” This isn’t the average office worker, flinging the last crumbs of lunch. Like the man in Melbourne, these feeders maintain a purposeful regimen. Lefebvre calls them “marginal city dwellers whose interests in life do not extend beyond feeding pigeons.” He describes, with disarming empathy, people who “wait outside the backdoors of restaurants for day-old bread and patiently soften all the bread and break it into little pieces and then hand it out to the pigeons.”

Without much effort, I began finding stories of such feeders in Michigan, Washington, New York, California — all eerily similar, as if they were proprietors in the same franchise. In Marin County, one was distributing organic polenta with pine nuts. In San Francisco, I met a white-haired Scottish widow who not only fed pigeons but also retrieved dead ones off the streets, wrapped them in plastic and buried them in trash cans.

Attempts to fine feeders have proved unpopular. (Shortly after Merchant left Melbourne, a local paper criticized the city for threatening an 87-year-old woman with a fine of nearly $8,000.) Feeders tend to believe the pigeons depend on them. Thus, PETA, in a pamphlet promoting PiCAS, recommends that the public-relations campaign accompanying any dovecote plan should “focus on the fact that a reduction in available food will not result in starvation for large numbers of pigeons.” Though such events are impossible to predict exactly, basic ecology suggests that pigeons, forced to expend more energy foraging, will disperse and slow their breeding.

“At the end of the day, pigeons are there because we’re filthy, dirty creatures,” Merchant told me. “They’re there because we’re stupid creatures who go on feeding them.” They are the heroes of a great co-evolutionary success story. One ornithologist has crowned them “superdoves.” The less deferential way of saying this is, we’ve taken an otherwise unobjectionable bird and built the perfect pest.

As our car idled beside the CBS studios in Hollywood, Laura Dodson pointed at birdseed spilled across several feet of sidewalk. “You can tell by the red stuff on top, the reddish glow,” she said. “That means it was poured this morning.” The pigeons, Dodson has noticed, eat the red bits first.

Dodson and Jeffrey Traill, two of the Argyle Civic Association’s most indefatigable pigeon combatants, had picked me up just before 7 a.m. to tour what they referred to as “the affected area.” Here, a woman named Susie Kourinian — they called her Bird Lady — had been routinely emptying entire 25-pound bags of birdseed from the rear door of her black S.U.V. “She’s like a stealth bomber,” Traill said.

Traill drove us to a squalid traffic triangle near the Capitol Records Building — the first place they noticed Bird Lady’s regular feeding — and then to a subway stop near Hollywood and Vine, where, they said, they often found hundreds of birds on power lines in the morning, waiting for food and spattering parked cars. At our next stop, a grocery store, anti-roosting spikes lined every light post and tier of the facade. But in a corner of the parking lot, pigeons indifferently pecked at a mound of fresh seed.

Pigeon feeding is illegal in Los Angeles in only a precisely delineated section of downtown around Pershing Square; it has been illegal there, and nowhere else in the city, for as long as anyone can remember, and for no immediately apparent reason. Attempts by the City Council to reason with Bird Lady, including at least one visit by a staff member to Kourinian’s place of business, have failed, and the Argyle Civic Association initially began lobbying to expand the law. To document the extent of the problem, they devoted most of April to ramshackle reconnaissance. Dodson says that their patrols began as early as 3 in the morning. They kept detailed logs of all sightings and videotaped Bird Lady in action; in stills, she pours a robust stream of seed from her waist like a cement mixer. They compiled “witness statements” from neighbors who had quarreled with her. Dodson, for her part, avoided any skirmishes. “Once we started this investigation,” she said, “my mouth’s been shut.”

Gradually, they built up an almost ethnographic understanding of Bird Lady’s routine, mapping 13 “known locations” where she fed. One day, Dodson says, she followed Bird Lady behind the Ricardo Montalban Theater, retrieved 45 empty birdseed bags from the Dumpster, then fanned them across her patio for a neighbor to photograph. Based on this evidence, the group approximated Kourinian’s annual outlay at 112 tons of seed and, using a scholarly article on pigeon metabolism (someone found it online), estimated that she sustained about 6,700 birds. This intelligence was compiled in what Dodson, handing me my own cumbersome copy, called “Bird Book.”

Susie Kourinian, aka Bird Lady, would not be interviewed for this article. She is from Armenia and works as a seamstress. (She is pictured in the March 2005 issue of Vanity Fair, pinning up Cate Blanchett’s gown.) Kourinian told The L.A. Weekly that after feeding Hollywood’s pigeons for 10 years, she had begun sleeping in her shop, afraid that Dodson and company would follow her and find out where she lived. (In truth, they already knew.)

Other local news organizations picked up the story, and this publicity, coupled with the Argyle Civic Association’s unrelenting street presence, had, it seemed, begun intimidating Kourinian, upsetting her routine and forcing her to move elsewhere, just as spikes and shock-tracks displace the pigeons. Seed was still turning up on sidewalks by the time Dodson, Traill and I rumbled around Hollywood in late June, but no one had seen Kourinian’s S.U.V. for some time. The existence of multiple Bird Ladies now seemed almost certain. “I’ve wasted so much gas watching her, it’s ridiculous,” Traill told me. “I think she just felt uncomfortable with me watching her like a hawk.”

At the traffic triangle, we had found only a lone, purple-headed pigeon, drinking from a leaky water pipe near a jacaranda tree. Sitting in Dodson’s dining room after our outing, I mentioned that the situation looked to be under control or at least to be shifting elsewhere. “She’ll just be back if we take the pressure off,” she shot back. Besides, Dodson had begun to fear that if Bird Lady were forced to stop feeding pigeons altogether, they would be unable to find enough food on their own. “They’d fall out of the sky,” she said. Having already refused options like Avitrol and trapping, the Argyle group was sworn to humaneness. Changing the law to make pigeon feeding illegal throughout the city was no longer a priority.

The group’s PiCAS phase, too, turned out to be short-lived. Even before I first arrived in Los Angeles, Dodson had another conversation with her contact at PETA, a wildlife biologist named Stephanie Boyles. Boyles told her about a pigeon contraceptive-feed called OvoControl working its way through the E.P.A.’s approval process. Dodson’s rank and file was relieved: replacing eggs sounded like a lot of work. “It was a hands-on thing,” Dodson said, “and we didn’t want to do hands-on.” And so, a month after voting in favor of PiCAS, the Argyle Civic Association voted unanimously to scrap that plan and wait to put pigeons on the pill.

Chemical pigeon contraceptives were first experimented with 40 years ago. Efforts to dose a flock of free-roaming birds inevitably require overcoming several ecological and logistical obstacles. In this case, how do you ensure that each pigeon eats the required five grams of OvoControl every day, for many months? And if other protected bird species eat any OvoControl, how do you ensure that they won’t be harmed? Many biologists, including Haag-Wackernagel, argue that it has been difficult to even gauge the success of contraceptives in the wild, since treated and control flocks can’t be isolated meticulously enough to be counted.

OvoControl’s manufacturer, Innolytics, contends that these issues are being resolved; in fact, its active ingredient appears to have shown much real-world promise in several multiyear Italian studies. Most appealing to Dodson’s group, the company says that OvoControl can succeed in Hollywood regardless of whether feeders cooperate. Innolytics might even hijack Kourinian’s flocks — setting automatic rooftop feeders to dispense OvoControl 15 minutes before she arrives in a given spot, reaching the pigeons with their small, contraceptive “snack” before she satiates them. Boyles, for one, says that if a program does eventually go forward, Kourinian could be persuaded to feed pigeons OvoControl instead of seed. “We can channel that energy, that desire she has to be productive,” Boyles told me cheerfully.

Guy Merchant was not as sanguine when I called to fill him in. He said he distrusted all chemical contraceptives and seemed incensed that Boyles had suggested it. “Stephanie Boyles and the staff of PETA haven’t a clue where PiCAS is coming from,” he said. He had just had a similar falling out with Melbourne, severing all ties after accusing the city of being “unprofessional” and willfully ignoring his instructions. (A Melbourne spokeswoman says, “He seemed upset about something, but we can’t figure out exactly what.”) OvoControl looks like an easy fix, Merchant said, but in his experience: “All of the good ideas don’t work. All of the things that would be great if they were true, aren’t.”

Pigeons, he seemed convinced, will frustrate whatever elaborate technologies we mobilize to suppress them. But PiCAS seemed to me to rely, every step of the way, on the perfunctory compliance of people. It is difficult to judge which, finally, is more exasperating.

In his paper “Regulation of the Street Pigeon in Basel,” Daniel Haag-Wackernagel writes that as the city’s 20,000 otherwise intractable birds were reduced to 10,000 by his methods, the flocks inside the lofts also decreased by half — from 1,400 pigeons to 708. Immediately after reading this, I was confused: if he had been removing the eggs of only 1,400 pigeons, what accounted for the depletion of the other 18,600 birds in Basel?

“This is the giant misunderstanding,” Haag-Wackernagel told me in his thick Swiss-German accent when I reached him at home. I had missed the point of his paper altogether. This amused him. Apparently it happens a lot.

The dovecotes were irrelevant, he said. The Basel Pigeon Action worked exclusively via “a change of public opinions” — a euphemism, it seemed, for an almost belligerent offensive against pigeon feeders. Just as PiCAS advises, Haag-Wackernagel flooded Basel with posters and advertisements characterizing pigeon feeding as “cruelty to animals” since it leads to overpopulation and overcrowding. For emphasis, he included noxious photos of squabs infected with parasites.

Citizens began ratting out feeders, sending Haag-Wackernagel names and the locations where they were regularly found. People began accosting feeders on the street, shaming them. “Although we certainly did not condone extreme action,” he writes, “in one case a pigeon feeder was even physically attacked.” One elderly man, perhaps finding no safe place left to feed pigeons outside, began luring them in through his apartment window. He was evicted.

The Basel Pigeon Action emerges as a case study in logic — purely ecological logic — taken to its extreme. Basel so thoroughly conceived of the city as an ecosystem that it treated humans like animals. And as feeders stopped flooding the system with food, Basel’s pigeon population waned. Of course, Basel’s game wardens were also offing thousands of pigeons to speed along this otherwise gradual process.

The lofts, he said, were showpieces — a ploy. By maintaining a few healthy flocks at the city’s expense, Haag-Wackernagel said he hoped that even the most steadfast “pigeon friends” would be convinced that Basel cared about pigeons and would trust him enough to stop feeding. Initially, feeders were allowed to feed these resident pigeons in designated areas, but Haag-Wackernagel said he quickly came to believe that “the idea of feeding only in certain places will never work.” Other pigeons swooped in, ate and flapped off to breed elsewhere.

Haag-Wackernagel told me he didn’t know much about PiCAS but had followed an unaffiliated consortium of cities employing dovecote schemes in Germany. These programs also cite his paper, he said, but he doubted that they are successful. He argued that they have misread his paper in precisely the way I had, or at least optimistically misappropriated it.

“If we could start again,” he told me, “if I was ordered to solve the pigeon problem in New York City for example, I wouldn’t use the pigeon lofts at all.” Not wanting to go back on Haag-Wackernagel’s word or evict the birds he raised there, Basel is still strapped with tending to them every week. In hindsight, Haag-Wackernagel says that any feeders reasonable enough to appreciate the gesture would probably have been reached by the logical appeals of the P.R. campaign alone.

“Most of the pigeon feeders are in some way crazy,” he said, summarizing, rather informally, a psychological study he helped write on the subject. “It is impossible to influence these people.” The most relentless have no family and few interpersonal relationships. They adopt pigeons as surrogate children. He described women — older women — who worked as phone-sex operators and prostitutes to pay for birdseed. This may be the pigeon’s greatest co-evolutionary triumph: the black magic whereby these grubbing little birds have sought out their depredated, human counterparts and transformed them into senseless disciples.

“They are like martyrs,” Haag-Wackernagel said. Ultimately, he conceded, his Basel Pigeon Action succeeded because, during those four years, “many pigeon feeders died.” They were old, and with the city so thoroughly re-educated, no younger people filled their emptied niche. There is a certain ecological elegance to this idea, too.

The great Pershing Square Pigeon War began in Los Angeles in February 1923. “I am a bird lover,” declared Milbank Johnson of the Pacific Mutual Life Insurance Company. “But as the city has grown from a village to a great metropolitan city,” he continued, rarefied businesses like his couldn’t keep scouring droppings from their facades and dislodging pigeon carcasses from their gutters. Pershing Square’s brand-new Biltmore Hotel — the largest hotel west of Chicago — was budgeting $500 a month for such drudgery.

Legislators banned pigeon feeding in Pershing Square park, writing the law that Dodson once hoped to universalize. But even the mayor scoffed at outlawing this “perfectly natural and harmless act,” arguing that it wouldn’t solve anything. “Every day,” a reporter wrote in The Los Angeles Times, “the city became more and more ridiculous to be thus thwarted by a lot of pigeons.” Finally, the city called in a “noted pigeon trapper of the High Sierras” to transfer the birds to the outlying hills near where, that very summer, tremendous white letters were being raised to spell “Hollywoodland.”

As cities like Los Angeles continued to sprawl, and hinterlands like “Hollywoodland” grew into hubs like Hollywood, countless animal species have been driven farther and farther out. We are now perhaps more starkly estranged from wildlife than any other humans in history, and we have come to mistake those animals’ absence from our daily lives as the natural order — an entitlement, even. Pigeons not only weathered that upheaval; they also managed to thrive in it. They are the holdouts, the spoilers. We resent them for this, and we want them to go away. Our finickiness is their last, great predator.

Scientists in the relatively new field of urban wildlife biology often talk about a species’ “cultural carrying capacity.” This is to say that, along with the amount of food and habitat available, many animals live and die by just how willing we are to put up with them. But the idea of cultural carrying capacity encompasses another equally un-Darwinian force that interferes with nature’s mechanisms: our compassion.

It’s our queasiness about harming pigeons that gave rise to the bird-control industry’s spikes, nets and shock-tracks — the shuffling of pigeons from one paying customer to the next. Our compassion for our own species, meanwhile, generally keeps us from tormenting those who, for whatever pitiable reasons, compulsively feed the pigeons — and who are, by feeding, extending what they can’t help seeing as the most basic form of compassion. Ultimately, it’s this niche that pigeons exploit: the rift opened between these virtuous ideals. We all mean well, and it’s easy to get tripped up in that same vertiginous territory while searching for a resolution.

A few days after I left Hollywood, Laura Dodson spotted Bird Lady’s truck and — feeling, spontaneously, that the time was right for reconciliation — pulled over. Kourinian told Dodson that she was catching a plane. Things in Hollywood had become miserable for her. She was going to Armenia for a few weeks, to think and be with family. “I said, ‘If you’re going to Armenia, what are you going to do about your birds?”’ Dodson told me, relaying all this. “She said, ‘I’m walking away from my birds, and I don’t care.”’

Dodson said she felt terrible. She tried to apologize. “I actually cried with her,” she said. The Hollywood Pigeon Action had, albeit unwittingly, attacked the problem at its human source. From a certain vantage point, this may have been its payoff. All Dodson had to do was patiently wait on OvoControl’s E.P.A. approval. And she has. But after devoting so much time to rustling up humane solutions, she was, above all else, concerned about the fate of the birds. She appealed to Kourinian again. But, Dodson explained, “she said: ‘I don’t care. My life is all broken up.”’

Dodson knew what she had to do. She conferred with Stephanie Boyles at PETA. Given the extent of Kourinian’s feeding, Boyles hesitantly agreed, advising Dodson “to err on the side of compassion.” And so Dodson called Jeffrey Traill. Together, they drove to a Wal-Mart some distance away. They bought a modest two-week supply, about 20 or 30 bags.

“We got the seed,” Dodson told me. “We started putting it out.”

PIGEON ASSOCIATED PEOPLE DISEASES

PIGEON ASSOCIATED PEOPLE DISEASES

Pigeon feces on building

Bird droppings on building window

Feral pigeons (Columbia livia) are not harmless birds. Many potential infections of humans silently exist in pigeons which are not apparent. They have the potential for transmission of over 30 diseases to humans plus another ten to domestic animals. Environmental pollution from pigeon droppings is quite evident. Air pollution involves more than noxious gases from automobile exhausts and belching smokestacks. One serious air pollutant is air-borne fungi, which are agents for infectious diseases. There is much information written about the problem, but it remains primarily in the professional journals and technical references, neatly stacked away on library shelves. The objective of this paper is to provide a brief account of the major diseases and to assess their importance. Feral pigeons have been identified with mycotic, bacterial, protozoal, chlamydial, rickettsial, and parasitic diseases as well as dermatosis (Weber 1979). MYCOTIC diseases are not transmitted from humans to humans. Perhaps this is why they do not make the headlines. The fungi causing the diseases are acquired by inhaling the fruiting bodies or spores along with particles of dust. The fungi live saprophytically in feces and soil. Aspergillosis is caused by Aspergillus fumagatus. The fungus produces toxins which poison the victim’s blood. Pigeons assist the spread of the spores in airborne dust. Blastomycosis is caused by Blastomyces dermatitidus. It primarily affects the lungs; the main route of infection is by inhalation of spores. The organism has been isolated from pigeon manure. Candidiasis is caused by Candida spp., chiefly C. albicans. Nearly one-fourth of all mycotic deaths are caused by this yeast. It often affects the mouth, respiratory system, intestines, and urogenital tract, especially the vagina. Incidence of candidiasis (yeast infection) in women is an increasing problem. The discomfort of the itching, pain, and discharge caused by the growth of this fungus is.

ignificant enough to warrant the elimination of pigeons which are one of the three wild birds most frequently infected with Candida. Cryptococcosis is caused by a systemic pathogenic yeast called Cryptococcosus neoformans. No organ or tissue of the body is exempt. It very frequently involves the brain covering as cryptococcal meningitis. One Indianapolis victim spent 91 days in the hospital with cryptococcosis. The yeast is carried in the intestinal tract of pigeons and deposited in their feces (Newberry 1967). One Kansas City survey showed that 93% of the pigeon coops were infected. Histoplasmosis is caused by Histoplasma capsulatum. It is interesting to note that the disease was suggested at one time as a biological warfare agent because of its airborne route (Furcolow, personal communication, 1960). It is probably the second most significant fungus disease. The “summer flu” that midwesterners used to get is now thought to have been histoplasmosis (Personal communication, American Lung Association, 1974). It is basically a pulmonary disease but may extend to the liver, lymph nodes, and spleen. The organism may disseminate to the blood and bone marrow and be fatal. It may lodge in the eye to cause ocular histoplasmosis. Twenty-two cases were reported to the Indiana Board of Health in 1976. Pigeon feces fertilize the soil in such a way as to give the fungus competitive advantage over other soil microorganisms. The largest outbreak ever recorded occurred in Indianapolis during the winter of 1978-79 with over 450 confirmed cases. There were 18 deaths. BACTERIAL DISEASES identified with pigeons are listed. Erysipeloid generally starts in a break in the skin and is accompanied with a sensation of burning, throbbing pain, and intense itching. It is caused by Erysipelothrus insidiosis. Pigeons are involved in its transmission. Listeriosis is caused by Listeria monocytogenes. It causes changes in the cells of the nervous system. It may cause conjunctivitis, endocarditis, and skin infections. It can also cause meningitis in newborns, abortions, premature delivery, stillbirths, and death. The organism has been isolated from pigeons. Parteurellosis is caused by a highly contagious bacteria, Pasteurella multicida. The 157 disease may be divided in four groups of syndromes: 1) infection of the upper respiratory tract as nasal discharge or conjuntivitis, 2) infection of the lower respiratory tract as bronchitis or pneumonia, 3) infecton of internal organs as appendicitis or inflammation of the urinary tract, 4) abscessed wound infections. Pigeons can spread the bacteria through their droppings or nasal discharge. The organism can live as long as a month in pigeon manure or three months in a dead pigeon. Salmonellosis is more than food poisoning. Gastroenteritis is the most common manifestation. Enteric fever or septicemia may follow several weeks later as a relapse. Septicemias often terminate fatally. Persistent infections are less common but very important. There may be an abscess or local infection as arthritis, bronchopneumonia, endocarditis, meningitis, osteomyelitis, or pyeleonephritis. Pigeons are important in the spread of salmonellae, since the bacteria are left wherever the pigeons defecate (MÜller 1965). They trample back and forth through their copious excretion on window ledges and air intake vents. Dusts to contaminate food or homes enter through air conditioners and ventilators. The most common salmonella Isolated from pigeons is Salmonella typhimurum var. Copenhagen, which is found in about 2% of pigeon feces (MÜller 1965). Yersiniosis is a plague-like disease by Yersinia pseudotuberculosos and Y. enterocolitica. The disease is clinically indistinguishable from appendicitis. Both diseases cause fever, nausea, headache, hard and painful stomachs. Because of the similarity, there were 32 school children hospitalized in Oneida County, New York in September 1976. Fourteen were reported to have had unnecessary appendectomies. Y.enterocolitica serotype 8 was isolated from the ill children. It was first isolated from pigeons in 1916. Transmission may be through the feces, eggs, or ticks of pigeons (Hubert 1972). PROTOZOAN diseases include American trypansomiasis, toxoplasmosis, and trichomoniasis. American trypanosomiasis is caused by Trypanosoma cruzi. There is no vaccine, effective treatment, or cure for the disease. It is transmitted through the feces of infected triatimid bugs, as the pigeon kissing bug (Triatoma rubrofasciata). The bugs tend to feed at night while the victim is asleep the bug defecates during or soon after engorgement, and most human infections occur when the bug feces are rubbed into eyes or mucous membranes following a bite. Toxoplasmosis may be one of the most widespread zoonotic diseases in the United States. It is caused by Toxoplasma gondii. It has been shown to cause abortions in women (W.J. Schneider, personal communication, 1977). The organism seems to have an affinity for brain tissue; it may cause mental retardation and death. Pigeons frequently transmit toxoplasmosis through fecal contamination, respiratory droplets, eye secretions, contact with infected tissue, or through ectoparasites. Trichomoniasis is caused by Trichomonas gallinae. It may affect the genital tract. Pigeons are considered the primary host, with about 80-90% of the adults infected. VIRAL diseases include encephalitis, meningitis, and Newcastle. Eastern equine encephalomyelitis (EEE) is the most deadly of the North American arbovirus diseases. It has been known to cause mental retardation, convulsions, and paralysis. The mortality rate may be around 60%. Pigeons are considered an amplifying host for the virus (Fothergill et. al. 1938). St. Louis encephalitis (SLE) affects the nervous system, ranging from complete recovery to disorganization, paralysis, coma, and death. The mortality rate is usually 5-10%, in some cases up to 33%. Pigeons, English sparrows, and house finches are the three birds labeled as main reservoirs of SLE. West Nile encephalitis ranges from mild to fatal Infections. The virus has been isolated from pigeons. Western equine encephalomyelitis is much more present and dangerous than most people think. The fatality rate has been between 5 and 15%. Children under one year of age may never recover from an infection of the virus, often becoming total vegetables. Pigeons are one of the amplifying hosts (W.F. Rathel, personal communication, 1977). Meningitis causes as inflammation of the brain and its covering. Pigeons are subject to meningo-encephalitis. Newcastle disease often involves conjunctivitis, lacrimation, and a mild influenza-like infection. Pigeons are the third largest common carrier; the virus has been detected in their feces. CHLAMYDIAL and RICKETTSIAL diseases. Chlamydiosis, caused by Chlamydia psittiaci, is a generalized infectious disease that causes a flu-like respiratory infection with high fever, severe headache, and generalized aches and pains. Mortality is usually 158 restricted to the old, the weak, or those with concurrent disease. Pigeons are the most common and consistent source of all known hosts (Terskiph 1961). Over half of the pigeon population is or has been infected. Q fever is caused by Coxiella burnetti. It is characterized by a sudden onset of pneumonitis, sometimes causing death. Pigeons are involved as carriers (Syrcuek et al. 1956). Investigators have isolated C. burnetti from the Kidneys of a large number of pigeons. The disease can be transmitted by infected ticks, ingestion, or by inhalation of dust contaminated with the organism. PARASITIC WORMS include cestodes and trematodes. Taeniasis by large tapeworm is caused by Taenia saginata, with specimens up to 50 feet having been recovered. Pigeons have been incriminated as potential vectors. Schistosomiasis, one of the most prevalent diseases throughout the world, is caused by a water-borne trematode. Pigeons are associated with flukes in the watery areas where they exist. Other pigeon associated trematodes include Echinoparyphium paraulum, Echinoparyphium recurvatum, Echinostoma revolutum, Haplorchis pulimio, and Hypoderaeum conoideum. DERMATOSIS. Acariasis is caused by infection of mites. Bird mites were responsible for a case of pruritis in a North Carolina hospital. The mites originated in a pigeon nest in the ventilator.

New study reveals deadly bacteria carried by Pigeons

New study reveals deadly bacteria carried by Pigeons

BioMed Central

A sampling of pigeons captured on the streets of Madrid has revealed the bacterial pathogens they carry. Researchers found two bugs that were highly prevalent in the bird population, Chlamydophila psittaci and Campylobacter jejuni, both of which cause illness in humans.

Fernando Esperón from the Animal Health Research Center, Madrid, Spain, worked with a team of researchers to analyse blood and enema samples taken from 118 pigeons caught using gun-propelled nets.

He said, “the present study demonstrates the extremely high prevalence of two zoonotic pathogens in feral pigeons in Madrid. At the same time, infection with these pathogens did not appear to be associated with any harmful clinical signs in the birds themselves. This leads to the hypothesis that pigeons act as asymptomatic reservoirs of Chlamydophila psittaci and Campylobacter jejuni. These birds may therefore pose a public health risk to the human population.”

Chlamydophila psittaci was found in 52.6% of the pigeons captured, while Campylobacter jejuni was present in 69.1%. Although there have been few reports of disease transmission between pigeons and humans, it can occur by aerosols, direct contact or indirect contact through food and water contamination.

According to Esperón, “Thermophilic Campylobacter species are considered the primary pathogens responsible for acute diarrhea in the world. In fact, in many countries such as England and Wales, Canada, Australia and New Zealand Campylobacter jejuni infection causes more cases of acute diarrhea than infection by Salmonella species.”

“Dirtiest Hotel in America” Looks to Clean Up

Dirtiest Hotel in America” Looks to Clean Up

A day after being dubbed the filthiest in America, a Tennessee hotel is pledging to clean up.

The Grand Resort Hotel & Convention Center was ranked the filthiest hotel in America, according to ratings compiled and released by the travel review site TripAdvisor.

The historic Smoky Mountains hotel in Pigeon Forge, Tenn., was graded “terrible” by 161 of 224 reviewers on the site. Twenty-six called it “poor” and 15 gave it an “average” grade.

But CEO and General Manager Nicky Darrell Chaney said he has already fired one manager, hired a new maintenance manager and new head of housekeeping, and is in the process of using a new sanitizer to clean the rooms, reports CBS affiliate WVLT in Knoxville.

“We knew we had some problems, and we’ve started to work on these problems,” said Nicky Chaney, President and CEO of the company that runs the hotel. Chaney took over operations in December and vows to restore their public image.

“I fired one of the managers, I hired new maintenance, and new housekeeper,” he said. “We’re proud of what we’re doing now, and were excited about where we’re going to be in the next few weeks.

Chaney took over just last month as president and CEO of KMS Enterprises, which runs the Grand and several nearby properties owned by hotel magnate Kenneth M. Seaton.

“This is an issue the company is taking very seriously,” Chaney said a statement Tuesday.

Seaton also is a defendant in a civil lawsuit alleging sexual harassment of two former housekeepers hired to work in KMS hotels, the Sentinel reports.

Meanwhile, the Grand will have to keep making changes to stay ahead of negative reviews – and the unwanted spotlight following the TripAdvisor “award.”

“This is a nasty place, would not let my dog sleep there,” reviewer LaFolettePat wrote last week under the headline “health inspector please.”

JordynC’s assessment: “If you are looking for a hotel with: pubic hair stuck to the bathroom floor in some unidentifiable, gelatinous liquid; chewing tobacco spit oozing down the halls and corridors; spiders actively making webs in every corner of your room; carpeting so greasy and dirty you wouldn’t want to sit your luggage down – let alone walk around barefoot; dingy bedsheets and towels as rough and thin as sandpaper; and a room so putrid and smelly it causes a gag-reflex when you walk in… by all means, stay at The Grand Resort.”

On Pigeon Patrol, Rufus the Hawk Rules the Skies Over Wimbledon

On Pigeon Patrol, Rufus the Hawk Rules the Skies Over Wimbledon

WIMBLEDON, England — Imagine the fluttering kerfuffle.

Roger Federer is serving for the Wimbledon title. He tosses the ball and cranes his neck.

Plop. A gift from a pigeon, right on the forehead.

Luckily, something like that hasn’t happened. At least not yet, not during a big match in recent memory.

For that, Wimbledon can thank a brown and chestnut bird of prey with keen eyes, a four-foot wingspan and bone-crushing talons. His name is Rufus the Hawk, and he plays a crucial role at the world’s oldest tennis tournament.

Every day, in the early morning, well before the matches begin, Rufus soars the skies over the All England Club, on the prowl for pigeons.

Without him, Wimbledon just might descend into aviary chaos. Pigeons could reign supreme, not just in the air, but also in the rafters, on the rooftops and across the grass courts.

The place is perfect for pigeons. “All of the grass seeds, all of the nooks and crannies, and the food waste from the fans,” Wayne Davis, one of Rufus’s handlers, said. Without Rufus, he reckoned, pigeons would number in the hundreds.

Wayne Davis, one of Rufus’s handlers, with a younger companion of the hawk. “Feral pigeons breed year round,” he said. “If you have just one pair breeding in the rafters at Centre Court, you would end up by the end of the year with about 40 more birds. You could have Roger Federer serving and clouds of pigeons wafting about.

“And pigeon poop, too, of course.”

Flocks of pigeons became a growing problem in the late 1990s, a threat to the prim fastidiousness that Wimbledon prizes above all. That was when the All England Club telephoned Davis and his family-run Avian Environmental Consult­ants.

Another of their birds was the first to patrol Wimbledon. Then Rufus the Hawk took over. He has become an English icon.

From dawn to dusk, he soars, on the prowl for pigeons. He doesn’t kill them. He toys with them, barreling from above, twisting, turning, squawking and nipping at their wings, announcing to all that the skies over Wimbledon belong to him.

“The pigeons learned he was in charge,” Davis said. “Other than a few stragglers, they stopped coming around like they did before. He scares them away.”

Rufus would have been a fearsome predator in the wild. Although he weighs just 1 pound 6 ounces, he cuts a much larger figure with his confident bearing and cascade of feathers.

He can spread his talons almost as wide as a person’s hand, and he can see 10 times better than any human. He can focus on a pigeon from a mile way.

Davis and his daughter, Imogen, feed him by hand because his weight is important. At less than a pound and a half, he can become too hungry and might have a pigeon for lunch. Maybe in front of the royal box.

They have taught him to come when they whistle.

Most often, he does.

Rufus soars and (almost) always comes back.

On one occasion three years ago, however, Imogen Davis had to chase him down at a nearby golf course. He took off again, across a road, then out of sight. She followed the jingle of his small bronze bell, attached to a talon.

She found him in the middle of a pond, standing in a thicket of weeds, hovering over a freshly killed duck. She couldn’t let him eat it. A full tummy would mean he wouldn’t come home until he was hungry again.

She waded through muck and lily pads, then through waist-high water. When she trooped back to Wimbledon, past crowds lined up to watch tennis in their finery, she had Rufus in her clutches.

One time, he vanished overnight.

Wayne Davis had left the bird in the family camper, parked outside an apartment they stay at during tournaments. Davis tucked him into the black cage that is his bedroom, and cracked a camper window just enough for ventilation. In the morning, Rufus and his cage were gone.

Someone had broken in and stolen him.

“My heart sank,” Imogen Davis said. She, her parents and her siblings had bought Rufus from a breeder when he was 16 weeks old, and he had become a member of the family.

“It was terrible,” she said. “There were a lot of tears.”

By then, Rufus had celebrity status, even a Twitter handle. The theft of Rufus the Hawk became headline news.

“Game, set and snatched,” wrote The Daily Mail.

The police said to expect someone to be in touch, demanding a ransom.

Three days went by. Then, from a phone booth, someone telephoned the Royal Society for the Prevention of Cruelty to Animals. No one knows for sure what had transpired — maybe Rufus had gotten away from the birdnappers, or maybe they decided to simply give him up — but he had been spotted in a park.

Imogen Davis, another handler, said Rufus once stayed in the Centre Court rafters overnight. The animal welfare charity picked him up. Rufus went back to work. He hasn’t missed a day since.

Imogen Davis said Rufus has taught her important lessons. Like the morning he flew into the Centre Court rafters and decided to stay there.

Two hours passed. Then five. Then 10. He still wouldn’t budge. “Luckily it wasn’t during the actual tournament,” she said, a nod to the fact that Rufus polices Wimbledon year round. She and her mother, Donna, wrapped themselves in towels and spent the night on Centre Court.

“We didn’t sleep in the royal box,” Imogen Davis said. “We didn’t sleep at all.”

The next day, Rufus came down.

The lesson was a lot like Zen: Rufus never gets ruffled. He does things in his own good time.

Has he ever, in his own good time, decided to perch in the Center Court rafters during a match?

No, Davis said. She chuckled. “But if he did, he would just stay perched up there, saying, ‘I don’t know who Roger Federer is.’”
