A new pathogen has been discovered by scientists investigating major die-offs of pigeons native to North America, according to studies led by the University of California, Davis, and the California Department of Fish and Wildlife.
Scientists were able to implicate this new parasite, along with the ancient parasite, Trichomonas gallinae, in the recent deaths of thousands of Pacific Coast band-tailed pigeons. The die-offs occurred during multiple epidemics in California’s Central Coast and Sierra Nevada mountain ranges. Scientists named the new pathogen, Trichomonas stableri.
Avian trichomonosis is an emerging and potentially fatal disease that creates severe lesions that can block the esophagus, ultimately preventing the bird from eating or drinking, or the trachea, leading to suffocation. The disease may date back to when dinosaurs roamed the earth, as lesions indicative of trichomonosis were found recently in T-Rex skeletons. The disease may also have contributed to the decline of the passenger pigeon, whose extinction occurred exactly 100 years ago.
Epidemics of the disease can result in the death of thousands of birds in a short amount of time. An outbreak in Carmel Valley killed an estimated 43,000 birds in 2007.
“The same parasite species that killed band-tailed pigeons during the outbreaks were also killing the birds when there weren’t outbreaks,” said lead author Yvette Girard, a postdoctoral scholar with the Wildlife Health Center in the UC Davis School of Veterinary Medicine at the time of the studies. “This indicates there may be other factors at play in the die-offs.”
“We are now investigating what triggers these die-offs, which may be caused by the congregation of infected and vulnerable birds during certain environmental conditions, or even spill-over from another nearby species,” said principal investigator Christine Johnson, a professor with the UC Davis Wildlife Health Center.
Between winter 2011 and spring 2012, there were eight mortality events – defined as more than five dead birds found in the same geographic area during the same time frame. The study said trichomonosis was confirmed in 96 per cent of dead, sick or dying birds examined at seven of the mortality events. This disease was also found in 36 per cent of band-tailed pigeons at wildlife rehabilitation centres, 11 per cent of hunter-killed band-tailed pigeons and four per cent of the birds caught live and released.
“What makes this disease more troublesome for band-tailed pigeons is their low reproductive rate – about one chick per year – and also that these events are occurring in the wintertime,” said co-author Krysta Rogers, an environmental scientist with the California Department of Fish and Wildlife. “That means almost all the birds we’re losing during events are adult birds. They’re being killed before they have the ability to reproduce in the spring.”
Mortality events in band-tailed pigeons have been reported in California at least since 1945 but have increased during the last decade, with outbreaks reported in six of the last 10 years.
“Going into the study, we expected to find a single, highly virulent species of Trichomonas in birds sampled at outbreaks,” Girard said. “Having two species killing birds at these large-scale mortality events is surprising.”
Necropsies of the birds were conducted at the California Animal Health and Food Safety Laboratory at UC Davis and the Wildlife Investigations Laboratory at the California Department of Fish and Wildlife.
Both studies were funded by the California Department of Fish and Wildlife and the US Fish and Wildlife Service.

A CAT has been decapitated and pigeons shot in a series of animal cruelty incidents across Sussex this week.
A domestic cat found with no head in a Peacehaven garden has been reported to Sussex Police by a horrified vet.
A force spokeswoman said police had no idea how the cat – which also had a missing leg and tail – had been injured.
The RSCPA is separately investigating violent thugs shooting pigeons in Hove.
A spokeswoman for Sussex Police said: “A decapitated cat was found in the back garden of a house in Capel Avenue, Peacehaven, by the home owner on Monday at 8.20am.
“The cat was also missing its front leg and its tail. It is not known who the cat belonged to and it was not microchipped.
“The incident was reported to the police wildlife officer for the area.”
Three shot birds were found in Sackville Road near the railway bridge on Tuesday. It follows an incident a few weeks ago in which three other birds were found dead.
Two pigeons were found in the alleyway behind a back garden, already dead, and a third injured bird was found inside the garden. They were taken to the vet who found a bullet in the body of the injured bird, which had to be put down.
RSPCA inspector Tony Pritchard said: “There are too many coincidences here for this to have been a one off occurrence or an accident – we are seriously concerned someone is intentionally shooting birds and may continue to do so unless they are stopped.
“It is likely that all the birds were left to suffer a long lingering death – as would have happened to the injured bird had these kind people not called us.
“We would like to remind people it is an offence to intentionally injure wild animals in this way and urge anyone who knows anything about the shootings to let us know.”
Under the Wildlife and Countryside Act 1981, killing or injuring a bird can result in a six-month prison sentence or a £5,000 fine.

In the dinosaur kingdom, the raptor reigns as a pop-culture bogeyman. While not as big as the T. Rex, the feathered creature had a mean set of teeth and claws. But there was at least one refuge from its tyranny: the air.
Now, however, scientists have discovered a new fossil that lays waste to that pleasant fiction. This new raptorial dinosaur named Changyuraptor yangi not only flew — it had four wings. And those wings were studded with the longest feathers any dinosaur has ever worn, said lead researcher Luis Chiappe of the Natural History Museum of Los Angeles.
“I’ve never seen anything like it,” he told The Washington Post. “It is a stunning specimen and it was stunning to see the size of the feathers. This is the dinosaur with the longest known feathers — by far. There is nothing like this by a very good distance. The feathers were one-fourth the size of the animal.” Chiappe paused for a moment. “It’s just wonderful,” he said.
In the pantheon of hulking dinos, this one wasn’t on the larger side. Published in the scientific journal Nature Communications on Tuesday, the article by Chiappe and colleagues reported it was only about four feet long and weighed about nine pounds — approximately three times the weight of your everyday seagull. But what it lacked in size, it made up for in importance, researchers said.
Classed as a “microraptorine,” its fossils “are essential for testing hypotheses explaining the origin and early evolution of avian flight,” the paper stated. “The lengthy feathered tail of the new fossil provides insight into the flight performance of microraptorines and how they may have maintained aerial competency at larger body sizes.”
Be nice if the WaPo would’ve told us this is from the Early Cretaceous (100-146M years ago). But anyway, that’s cool.

LAKE ALFRED, Fla. (AP) — Every evening they come.
After a day of circling the skies, scanning the ground for the dead and dying, they make their way back home — an inhospitable home, to be sure, but home.
During the past couple years, it has been turned into a fake bird cemetery; it has reverberated with loud, scary noises; it has sent electric jolts through their bodies; and most recently, it has flashed blinding light into their eyes.
But still, black vultures settle down each evening on the Lake Alfred water tower.
“We are kind of in the final attempts (to get rid of the vultures),” City Manager Ryan Leavengood told the City Commission last Monday. “You wouldn’t think these things are as resilient as they are, but I’ll give them credit where credit is due.”
Leavengood’s comment sparked laughter from the commissioners and audience, but the city has had about $24,000 worth of work done to try to persuade the vultures to settle somewhere else.
The city has tried using a buzzer to frighten them — which worked until they got used to the noise. Fake dead vultures didn’t work, either. Those attempted solutions cost about $2,000.
Commissioners accepted a $20,332 bid in November for Terminix to install bird spikes and low-voltage electric tracks on the tower. The tracks were supposed to give the birds an uncomfortable, but harmless, shock. The spikes were supposed to make the surface uncomfortable to perch on.
Public Works Director John Deaton said the electric track works but doesn’t cover the whole tower, leaving plenty of space to sit comfortably. The spikes don’t seem to do anything, he said.
Leavengood said Monday the city will pay only part of that cost because it failed to deter the birds.
“Ultimately, we paid for a solution, and we didn’t get a solution,” he said.
In an attempt to hold on to hope, the city bought two Eagle Eyes for about $1,600 in May.
Eagle Eyes are bird deterrents that reflect sunlight or artificial light, limiting birds’ vision and causing them to steer away and find somewhere else to land.
It doesn’t seem to work for vultures, though.
“It looks pretty flashing around out there,” said Public Works Director John Deaton. “But the vultures are not annoyed by it at all.”
Leavengood said the city has another last-ditch effort idea: putting up cables and wires to impede their ability to land.
“That’s about the last thing we can think of,” he said. “We were hesitant because we didn’t want them to get caught up” in the wires.
City staff members have said they want the scavengers to find a new place to perch because they are worried about damage to the tower. Vultures’ urine and regurgitated fluids are highly corrosive.
So far, the only damage has been to the paint. The vultures have no access to the water, so the water quality isn’t in danger.
But cleaning and painting the tower is costly. Staff and residents don’t find the sight of the birds particularly appealing, either.
Vultures are a protected species, and the city cannot do anything to remove the birds that would harm them.
“You know what it is?” Deaton said, with a laugh. “Lake Alfred is a great place to live, and the birds have figured it out, and they don’t want to move.”

A day after more than 50 pigeons were found dead in Nehru Rose Garden under mysterious circumstances, the post mortem report said ‘electrocution’ is the reason behind the deaths.
Municipal Corporation got post mortem done from Government Veterinary Dispensary, Haibowal. The report was out on Saturday which said that ‘even healthy birds have died showing symptoms of electrocution.’
Talking to Newsline, A S Sekhon, health wing incharge of MC, said, “Postmortem has confirmed that reason behind death was electrocution. “It has been found through the colour of the birds after death and absence of injuries.
“The report adds that entire internal functioning stopped suddenly which is not at all a possibility unless something happens like electrocution. Also majority of birds that died were healthy.” He added that MC was able to recover around 25 dead birds and post mortem was performed on three of them.
Also since, there was no wire or pole near the spot, thunderstorm is being suspected as reason of electrocution. On Thursday night, the city witnessed hailstorm and thunderstorm.
Morning walkers at Nehru Rose Garden were in for a horrendous surprise on Friday morning when carcass of numerous pigeons were scattered all around the place.
City’s rose garden presents an utter dismal picture as it once had a full fledged zoo which stored monkeys, deer, ducks and rabbits for children to visit. Now it houses nothing except pigeons after similar incident happened on 2012 when rabbits were found dead on April 28 and reportedly the cage was left open due an employee’s negligence.
