Q. Pigeons are everywhere, but has anyone ever seen a baby pigeon?
A. No. They are mythical creatures born in adult form, like the Greek goddess Athena when she sprang from the head of Zeus.
Just kidding, of course: Pigeons are secretive birds, and as such like to build their nests in hidden locations. What’s more, it takes only a month for a chick — properly called a squab, informally known as a squeaker — to become fully developed and leave the nest, limiting the time you have to come across one.
The feral pigeons that inhabit the city today are the descendants of wild rock pigeons, also known as rock doves, which are native to Europe, northern Africa and southwestern Asia.
Wild pigeons build their nests in places unlikely to be disturbed by other animals, such as on cliff faces. Window ledges, rooftops and scaffolding serve as stand-ins for their cosmopolitan relatives.
When a male pigeon looks for a mate, he finds a good nesting spot before launching into his mating call. If he is successful, the female remains at the site while the male brings twigs and other materials to build the nest.
Both parents take turns incubating the eggs, which typically come in pairs and take 16 to 19 days to hatch. The chicks are born helpless, covered with yellowish-brown fuzz; nourishment comes from a white substance called “pigeon milk,” which their parents regurgitate into their mouths.
One New Yorker who has seen her share of squabs is Rita McMahon, co-founder and director of the Wild Bird Fund, a nonprofit that rehabilitates wildlife of all kinds.
On a recent afternoon, several large birds roamed freely around the organization’s Upper West Side headquarters, including a juvenile swan named Warrior who had found himself frozen in ice in Prospect Park. (“They’re just young and stupid,” Ms. McMahon said. “They don’t know winter yet.”)
There were no baby pigeons, however. Ms. McMahon estimated that squabs account for one-sixth of the 6,000 birds her team treats each year. The flow is fairly consistent, as pigeons, which have an expected life span of two to three years, mate year-round.
Many patients arrive with broken legs. That’s because squabs nearing maturity go through an angst-filled teenage phase, which can result in a desire to leave the nest prematurely.
“If they come out too early and they don’t have the wings, all the flapping in the world isn’t going to keep them from hitting hard,” Ms. McMahon said.
This risky period requires the parents to navigate between protecting the squabs from harming themselves and letting them go free. If their young become overly dependent, for example, they could have a difficult time making it on their own.
Human guardians can be faced with the same challenge, as one Metro reporter for The New York Times discovered last year when he raised a pair of baby pigeons in his bathroom.
“You get very attached to them,” Ms. McMahon said. “They are charming.”

The big-hearted rescuers then used a tube to administer air from a ventilator until the wild creatures coughed back into life.
Passer-by Sim Wright, 49, snapped the bonkers scene as he passed the depot in Colchester, Essex.
The marine biologist said: “We heard what sounded like explosions coming from the depot so we thought it was best to get out.
“When I went round the back, I could see they were looking for people in the building and when they were sure no-one was trapped, they turned their attention to the birds.
“They were carrying the birds out by hand. They had passed out from smoke inhalation.
“They got them on to the ground and they started feeding them water out of a cap to revive them.
“Then I was really surprised because they used a tube to feed them oxygen which really seem to do the trick.
“When I saw it, being a marine biologist, I was really taken with the care they were displaying to the animals.
“Obviously, their first priority is for humans but once they had ascertained there was no-one in there, it was really great to see how quickly they turned their attention to the birds. Soon after I took this they were walking around the place and looked okay.”
Essex County Fire and Rescue Service said the firefighters were called to the blaze on Friday, May 18.
A spokesman added: “This is a great example of the compassion our firefighters show on a daily basis across our county.”

A BIRD found itself before the beak after sneaking into a courtroom and leaving deposits everywhere.
Although there are no windows in the room at Swindon Crown Court, the pigeon somehow managed to get in and make itself at home.
And it was still there this morning when legal business was due to start, resulting in one case being moved to another courtroom while another matter was delayed.
Efforts are being made to remove the bird from the building.

When a group of students discarded an old mop on their dormitory balcony before the holidays they didn’t give it a moment’s thought.
But when they returned after the break they found a family of birds had made a nest on top of the mop head.
Now their balcony is home to a group of baby pigeons.
A picture of the scene was posted online by one of the students who uses the Reddit handle Aelegius.
“I live in a dormitory in Estonia and one of my roommates threw one of our old mops out on our third-floor balcony,” Aelegius told the Press Association.
“We often see pigeons around our building, but would never have thought they’d decide to nest here.
“We had a few weeks’ break from school for exam preparation and discovered those baby birds when we returned. I couldn’t describe my surprise upon seeing them.”
The birds had fashioned a regular nest of twigs on top of the mop head, with a wall giving them am extra buffer from the wind.
“I had never before seen baby pigeons before. I adore watching our pigeon family outside our kitchen window.”
Aelegius, who is due to graduate this year and then go to university, added: “The balcony had turned into quite a mess though, so we’ll definitely remember to not leave any mops out in the future.”

A disease in pigeons and doves gained infamy in 2006 after it decimated the UK’s greenfinch bird population by half a million within that year. In 2012, the bird’s population had plummeted to 2.8 million from an estimated 4.3 million. A new study has now found a protozoan parasite that was implicated in the disease in common mynas in Faisalabad, Pakistan.
The disease, avian trichomonosis, is an emerging infection more colloquially called frounce or canker. It wreaks havoc on both endangered and common wildlife populations. The parasite responsible for causing it, Trichomonas gallinae, is known to normally affect pigeons, doves and the birds of prey that eat them.
But in 2005, it jumped species and devastated the UK’s garden songbird populations of greenfinches and chaffinches. Some earlier studies have pointed out that they probably had a major role to play in driving the passenger pigeon to extinction, and that they are causingpopulations of the endangered Mauritian pink pigeon to fall. (Interesting aside: a T. gallinae-like protozoan had commonly infected the dinosaurs as well.)
Trichomonosis affects the upper respiratory and gastrointestinal tract of birds. Affected birds develop lesions in the mouth and/or oesophagus and show signs of lethargy and laboured breathing. Some of them drool saliva and have wet plumage around the bill. T. gallinae can’t survive outside the host and is vulnerable to dehydration. The parasite is transmitted when infected birds share their food and water with others.
Common mynas roost with the blue rock pigeon, the latter a species that hosts T. gallinae in their bodies without harm to themselves. Since mynas are also known to eat pigeon and dove fledglings, researchers already suspected that the disease had jumped species.
Mynas are highly adaptable and live and breed in a wide range of climates. They are also known to evict other resident birds from their nests, earning them the sobriquet ‘kalahapriya’, Sanskrit for ‘quarrel-lover’. Though native to Asia, the myna has thrived in new environments to which it has been introduced.
In fact, according to the International Union for the Conservation of Nature (IUCN), it’s one of the three bird species on the ‘world’s 100 worst invasive species’ list. Given its runaway success in occupying new territory, the myna’s ability to spread diseases to other susceptible domestic and wild avian species in other parts of the world is a matter of grave concern.

The researchers, from the University of Agriculture in Faisalabad, the King Saud University in Riyadh and the University of East Anglia, Norwich, captured 167 mynas across eight sites in Faisalabad to screen for T. gallinae. They used a binomial sequence-based genotyping system, where genetic variation is measured in predetermined DNA sequences, and found that about 20% of the birds were infected with the disease.
The infection rates were lowest in places where the contact between mynas and blue rock pigeons was limited. At the same time, the infection itself was widespread: there were infected mynahs in all the surveyed sites.
The study’s authors have inferred that the disease in mynahs was endemic, i.e. restricted to a particular region. Farah Ishtiaq, a disease ecologist at the Indian Institute of Science, Bengaluru, who was not involved in the study, thinks this is a bold claim to make because it has not been explored elsewhere and because there has been no evidence thus far for this claim.
According to Kevin Tyler, a cellular microbiologist at the University of East Anglia and one of the authors of the study, the genetic subtype, or strain, affecting the mynas was different from the one affecting European finches.
He also said in response to Ishtiaq’s comment that the subtype had been found at all sites at a similar level at different times. Together with the fact that T. gallinae did not appear to be causing severe disease, “our interpretation … is that this is consistent with the disease being endemic in this region rather than a recent outbreak.”
Spencer Greenwood, a professor at the University of Prince Edward Island, Charlottetown, who was not part of the study, also found the endemism claim reasonable given they had only found one genetic subtype and that most birds had not shown evident signs of the disease.
Then again, only 11 out of the 33 infected mynas had exhibited signs of poor health, suggesting they were able to carry the infection without fatal consequences to themselves while potentially being able to spread the disease to other species. However, more studies will have to be conducted before we’re sure whether mynahs are a reservoir or a dead-end host. This is because the mynas have the potential to be a reservoir for this disease. Though the authors have found infection, the study does not address transmission to and from mynas as hosts.
The infection incidence was higher among male mynas than female ones. Nicholas Clark, a postdoctoral fellow at the University of Queensland, Brisbane, who has studied avian malaria in mynas, said, “Perhaps the males are more likely to come into close contact with pigeons and doves.” He added that researchers would have to study the behavioural ecology of males and females in the nest to know more. He was not involved in the study.
However, Ishtiaq said that mynas have no sexual dimorphism – so sexes can’t be told apart without surgical or molecular testing. So it would be easy to over- or under-estimate the number of birds of either sex.
But Tyler is confident about being to use subtle differences in morphometric measurements to their advantage. In this study, the researchers were familiar with the captured mynas and could confidently ascribe sex. Nonetheless, he and his colleagues remain unsure as to why mostly male mynas were infected with trichomonosis.
Greenwood said other aspects, such as a myna’s roosting behaviour, weather conditions, availability of food, closeness to breeding season, etc. need to be considered to figure out why more males seem to be infected.
He also thinks that sampling the pigeons that share habitat with the mynas and determining what type of strains they carry would be important. “It would be interesting to see if they have the same subtype and if they do, at what prevalence do they occur compared to other subtypes.”
Protozoan parasites cause some of the world’s worst diseases. Because a lot of them are restricted to the developing world, studies such as this demonstrate the importance of studying emerging infectious diseases and their social and economic repercussions. “Mynas have already been implicated in the spread of bird flu through contact with poultry,” Tyler said, “so this could be of concern to poultry farmers.”
His team plans to work with groups in India and other places where mynas thrive.
Ishtiaq thinks that they have made a good start in understanding the host and geographical range of trichomonosis, and feels it would be good to test the common rosefinch for T. gallinae. This is the only finch species that migrates to South Asia and comes in contact with other resident birds. “I have seen many shared avian malaria parasites between resident finches and common rosefinch,” she said.
