Why Are There So Many Pigeons?

Why Are There So Many Pigeons?

They peck at the pavement; they coo overhead; they swoop in hundreds across town squares: Pigeons have become such a permanent fixture in our urban landscapes that cities would seem oddly vacant without them.

But while many people harbor resentment for these ubiquitous creatures — labeling them “rats with wings” — few of us stop to ponder how pigeons became so numerous in the first place, and what our own role in their urban colonization might be.

Today, in fact, there are more than 400 million pigeons worldwide, most of which live in cities. But that wasn’t always the case. The city pigeons we know today are actually descended from a wild creature known as the rock dove (Columba livia): As its name suggests, this bird prefers a rocky coastal cliff habitat to the conveniences of city life. [Why Are Chickens So Bad at Flying?]

But going as far back as 10,000 years ago, written and fossil records show that people living in ancient Mesopotamia (modern-day Iraq) and Egypt began coaxing these doves with food into human-inhabited areas, encouraging them to roost and breed on their land. “Back then, we brought rock doves into cities to eat as livestock,” Steve Portugal, a comparative ecophysiologist who studies bird flight and behavior, told Live Science. The plump, young birds especially — known as “squabs” — became a prized source of protein and fat. People then began domesticating and breeding the birds for food, creating subspecies that led to the diversity of urban pigeons known today.

Along the way, humans began to realize that pigeons were useful for much more than their meat. As the birds grew more popular in the Middle East, North Africa and Western Europe in the ensuing centuries, people began to tap into their innate talent for navigation — the same skill that makes homing pigeons famous today. Ancient records show that Mediterranean sailors used the birds to point floundering ships toward land. In cities, they became increasingly valuable as airborne messengers that could deliver important information across large distances.

From there, humanity’s appreciation for the animals only grew: Although pigeons were initially domesticated as a food source, “as other poultry became more popular, pigeons fell out of favor for eating and people began breeding them as a hobby,” said Elizabeth Carlen, a doctoral student at Fordham University in New York City who studies the evolution of urban pigeons.

By the 1600s, rock doves — non-native to the United States — had reached North America, transported by ships in the thousands. Rather than being a food source, it’s most likely that the birds were brought across from Europe to satiate the growing pigeon-breeding trend among hobbyists, said Michael Habib, a paleontologist in the Dinosaur Institute at the Los Angeles County Museum of Natural History, and the University of Southern California.

Inevitably, birds escaped captivity, and began to breed freely in American cities. “We created this novel [urban] habitat and then we basically engineered an animal that does very well in that novel habitat,” Habib told Live Science. “They were successful in cities because we engineered them to be comfortable living around humans.” [Do Birds Really Abandon Their Chicks If Humans Touch Them?]

Cities became the perfect backdrop for the pioneering pigeons’ success. “Pigeons are naturally cliff-dwellers and tall buildings do a pretty great job at mimicking cliffs,” Carlen told Live Science. “Ornate facing, window sills and air-conditioning units provide fantastic perches for pigeons, similar to the crevices found on the side of a cliff.”

Another trait that makes pigeons more adaptable is their appetite. While other bird species have to rely on supplies of berries, seeds and insects, pigeons can eat just about anything that humans toss in the trash. “Other species are specialists and pigeons are the ultimate generalists,” Portugal said. “And the food is endless: I don’t think too many pigeons go to bed hungry!”

The pigeon’s unusual breeding biology seals the deal: Both parents rear their chicks on a diet of special protein- and fat-rich milk produced in a throat pouch called the crop. So, instead of having to rely on insects, worms and seeds to keep their young alive — resources that would be scarcer in cities — pigeons can provide for their offspring no matter what, Portugal says: “As long as the adults can eat, they can feed their babies, too.”

All these traits give pigeons a competitive edge compared with other species that might attempt survival in cities. Combined with the pigeon’s prolific breeding habits (parents can produce up to 10 chicks a year), it’s easy to see why these birds have become so populous around the world.

Not everyone appreciates the urban phenomenon that these birds have become — hence the “rat with wings” moniker. That’s understandable to some extent: Pigeons can spread diseases, and the mounds of guano they splatter across buildings can be cumbersome and costly to clean.

Despite this, Portugal sees a benefit to their presence in our urban environments. “They’re actually one of the few bits of wildlife that people get to interact with in cities now,” he said. What’s more, “they’re super-adaptable and super-successful; they’re the ultimate survivors. Actually, we can learn a lot from them.”

Pigeons As Pets: Outside or Indoors

Pigeons As Pets: Outside or Indoors

Pet lovers are embracing the joys of adopting dogs and cats from shelters in ever greater numbers, but few people realize how many birds there are in shelters and rescues needing to be adopted.

Pigeons Make Great Pets — And They Need Our Help

I started Palomacy (originally named MickaCoo Pigeon & Dove Rescue) in San Francisco, CA when I discovered domestic (unreleasable) pigeons were being killed in shelters for lack of homes. Pigeons such as Kings, Fantails, Tumblers and Homers are smart, beautiful and gentle birds. They’ve been selectively bred and tamed and, while they can’t survive in the wild, they thrive as pets. Many pigeons (and other birds as well) wind up in animal shelters, either surrendered or found as strays, but they need adopters to get out alive.

Pigeons make great pets both indoors as part of the family or outside in a rodent and predator-proof aviary.

Pigeons as Pets in an Outdoor Aviary

Rescued pigeons can’t be safely flown (they are easy targets for hawks and cats) and so, when outside, must be protected in an aviary. It needs to be predator-proof (sturdy and securely built all the way around including top and bottom), rodent-proof (use 16 gauge or better hardware mesh with openings half inch or smaller) and include a sheltered corner that will stay shady on the hottest days and dry during the rainiest. No one has ever wished for a smaller aviary so make it as big as possible. Minimum size for four birds would be at least 6 feet long by 4 feet deep and 6 feet high.

Pigeons excel at the leisure arts and spend their time bathing, preening, lounging in the sun, foraging for favorite seeds, watching the sky, napping, showing off and courting. Every four to five weeks, mated couples will lay a pair of eggs (which need to be replaced with fake eggs for pigeon birth control) and take turns sitting on them. Pigeons are extremely devoted to their family and mate for life. They require fresh food and water and a quick poop-scrape daily and a thorough aviary cleaning weekly. Pigeons are beautiful, peaceful and full of personality. With time and attention, most can be hand-tamed. All can be befriended. It’s easy to create a charming, attractive and safe aviary for rescued pigeons.

Pigeons as Indoor Pets

Pigeons can also live inside with the family. They need a big cage for their home base (a double-flight cage or an extra large dog kennel is a good size for a pair) with daily out-of-cage time to stretch their legs and wings and have some fun. They’ll walk around more than fly and will pick out some favorite spots for hanging out. Pigeons are smart, easy going birds that quickly learn household routines. They do fine in homes with other pets and can live peacefully and unafraid with dogs and cats as long as they are kept safe. Pigeons are very emotional and do need a BFF, whether another bird or a human with whom they can spend the day. (Home all alone in a cage isn’t a good life for a pigeon.)

Using Pigeon Pants for Indoor Birds

The main inconvenience to having pigeons as indoor pets is probably their droppings. Healthy pigeon poop is odorless and not too hard to manage with hardwood or tile floors or with strategic placement of liners. Pigeons can also be potty trained or they can wear pigeon pants! Pigeon pants are adorable little harnesses with a diaper to catch droppings. The pants are easy to put on and pigeons tolerate them well. Once dressed, they can walk and fly around the house and sit on laps and shoulders poop-free. The diaper, lined with half a panty-liner, should to be changed every 3 hours.

Tastes Like Chicken

Tastes Like Chicken

The bird was still steaming as I cut into its succulent red breast. It had spent the day marinating in honey, thyme and vinegar, and now came the roasty aroma and the moment I’d been waiting for: the first moist, silky bite. Surprisingly gamey, the flavor reminded me more of an elk steak than any poultry I’d ever eaten. So this is what pigeon tastes like!

Yes, I served pigeon for dinner, though eaters call it by another name—squab. Long before they were regarded as an urban plague, the hearty little birds served as a staple food and even delectable delicacy, from ancient Egypt to medieval Europe and into modern North America. Only in the past century or so have the birds fallen from culinary grace.

Today, pigeons have found themselves, well, pigeonholed into two groups: the ubiquitous and reviled rat with wings, and a succulent entrée on haute menus. While no New York eater would dream of cooking up the feral fowl, the domestic variety’s pedigree justifies indulging in Thomas Farm’s squab with foie gras–madeira emulsion on Per Se’s $295 winter tasting menu before catching the latest opera. But while they may not flock together, these are indeed birds of a feather.

As lamb is to mutton, veal is to beef, and Cornish hen is to chicken, squab is just another name for a young pigeon, harvested when it is plump enough to satiate an empty stomach but tender enough to please the palate. So how did this divide come about? Is there any difference between the sidewalk scourge and their country cousins cooing on upscale organic farms? Does that which we call a squab by any other name still taste as sweet?

Ancient Egyptians kept domesticated pigeons, which doubled as messengers and main courses. Pigeons carrying postal messages regularly announced arriving visitors, according to records from 2900 BCE, and ancient art depicts Queen Nefertiti handing a pigeon to her young daughter while servants roast the birds.

Starting in the Middle Ages, French lords and ladies considered pigeons a delicacy. The bird’s dung made excellent fertilizer, and its rich red breast earned it the nickname “the bird of royalty.” For several centuries, nobles built elaborate dovecotes to attract feral pigeons (doves are the romantic members of the family Columbidae, which they share with pigeons), though their serfs hated them. The lowly peasants had to feed the voracious birds from their own grain yields and clean up their abundant dung. When the Revolution struck in the 1789, many of the dovecotes—which had become a symbol of aristocracy—were destroyed.

Rock pigeons—the species with whom New Yorkers share our streets—made their landing in the United States precisely because of their tastiness. French settlers introduced the birds in the 1600s, helping to expand their natural range of Europe, North Africa and South Asia into the New World. Early Americans also feasted on the local varieties, like the passenger pigeon, which they quickly began munching into extinction. Though numbering in the billions when Europeans first arrived, passenger pigeons were exploited as cheap food in the 19th century; Martha, the world’s last passenger pigeon, died in 1914 at the Cincinnati Zoo.

While Americans had long caught wild squab or tended small farms flocks, the first U.S. commercial breeding facility for squab popped up in 1874, with production ramping up in the years following. By 1907, hundreds of breeding facilities dotted the country, primarily to sell to restaurants. Some chicken farms were even converted to squab operations, while facilities in Bridgeton, New Jersey, alone raised thousands of birds dubbed “Jersey Squab.” The Great Depression brought the price of squab plummeting to that of chicken, pork or beef, which, according to Wendell Levi, author of the 1941 book The Pigeon, “allowed the housewife to include squabs in her family menus.”

But as factory farming spread its wings, a competitor displaced squab from the American menu: chicken. Agricultural economists found that while you can fatten a pigeon, you can fatten a chicken faster, explains Colin Jerolmack, a professor of sociology and environmental studies at NYU who recently authored a book called The Global Pigeon, due to arrive on shelves February 2013. By World War II, the sun had set on squab’s long heyday.

Meanwhile, as squab retreated from the family dinner table, Americans were coming to know the bird not for its plump place on the plate but for its unwanted urban ubiquity.

Jerolmack’s paper “How Pigeons Became Rats” describes an early instance of public pigeon-hating. Up until the 1960s, some parks even had designated pigeon feeding areas, but around that time a NYC park commissioner referenced the “filth and disorder” of Bryant Park brought upon by “winos,” “homosexuals” and pigeons. Public health officials (inaccurately) referenced the birds in connection with diseases, which helped solidify their low status. By 1980, when Woody Allen declared pigeons “rats with wings,” the birds were widely reviled.

“When you go to a restaurant and ask the waiter what squab is, they’re hesitant to answer,” Jerolmack says. “A lot of people think it’s a wild game animal,” he says. But today, the squab served at upscale restaurants and specialty butchers is usually raised on poultry farms.

Ariane Daguin, the famous French tastemaker behind gourmet ingredient supplier D’Artagnan, has helped Americans forget prejudices against fowl and other fauna. (Her father, Michelin-starred chef André Daguin, remains a star for championing magret, the large breast of the Moulard— the duck breed prized for foie gras—served rare.) In New York Daguin is very well known for foie gras, and, to a lesser extent, rabbit—both meats that are beloved in France but have something of a PR problem in America. Pigeon fits that portfolio perfectly, and under her wing, the bird has found favor here, albeit not under that name. Today D’Artagnan provides most fine Manhattan restaurants with their squab, dispatching 1,800 to 2,500 birds per week.

D’Artagnan offers several breeds of squab, but the King breed is their star. “I really fell in love with that when I arrived here because we don’t have that breed in France, and it’s exceptionally plump,” says Daguin. “I think I’ve been raving so much about it that some people in France have now brought it there.”

D’Artagnan sources squab from a cooperative of free-range farms in California. They’re harvested at about 28 days old, when the squabs reach adult size but before their young muscles toughen. “We have a very funny way to test whether the squab are the right age when they arrive at our loading dock,” Daguin says. “We open the cages, and if they fly out, that means they’re too old.”

In addition to their farm-raised squab, D’Artagnan also sells wild birds called wood pigeons. The animals come from Scotland (game hunted on U.S. soil cannot be legally sold) and are a bit smaller and leaner than the domestic squab, tasting of “true wild game,” Daguin says.

In France, dining on little pigeons is still a big thing. And here in the States, she reports a growing demand among chefs but also on the part of home cooks, who order the birds through her Web site. “People are starting to understand how delicate and rich squab is, and how easy it is to cook,” she says.

As for the city flocks, Daguin says, “unless you are dying and it’s a survival thing, I would never eat them.” But it’s not disease that makes pigeon a poor fit for dinner. Pigeon plagues are more or less a myth; they carry no more infectious pests than any other bird, including chickens and turkeys. Far more treacherous is the sidewalk birds’ diet. “As soon as wild animals are too close to man, they eat things that man rejects,” Daguin says. Jerolmack points out that feral pigeons could be eating rat poison, metals or battery acid—all things that cooking would not neutralize.

Nonetheless—and you might not want to read this while eating—a recent spate of pigeon nabbing has sparked rumors that some street birds indeed end up under knife and fork. A few enterprising individuals scatter birdseed to attract a feathery flash mob, then snatch the birds up in nets and stuff them into the back of vans. Most seem to wind up on live shooting facilities in Pennsylvania. But during his research, Jerolmack met some of these shady snatchers. “I’ve heard—but cannot confirm—that some street pigeons get sold to live poultry markets,” he says.

At such facilities in East Williamsburg and Bushwick, mostly serving a Hispanic clientele, live pigeons can indeed be found alongside ducks and chickens but the animals’ origins remain unconfirmed. “People know they’re not supposed to be selling street pigeons,” Jerolmack says. “If a poultry market is selling them, they’re selling them to customers who assume they’ve been bred.”

And though some media outlets reported a gang of vagabonds roasting pigeon over an open fire last summer in Prospect Park, officials told Edible that those claims were untrue.

Given the city birds’ trash-can diet, even hardcore locavores will want to leave them be. Instead, for eaters interested in tasting one of mankind’s longtime favorite flavors, L. Simchick butcher in the Upper East Side carries Daguin’s farm-raised birds for $22 a pound, or you can head down to Chinatown where frozen birds go for $7.89, or fresh ones for $14. While you’re in the neighborhood, swing by Columbus Park to see if you can spot one of those infamous pigeon-snatchers, or just to feed the birds.

Habit and Habitat of Pigeon

Habit and Habitat of Pigeon

The Blue Rock Pigeon lives in perfect freedom in ledges, fissures and holes of rocks, forts, old buildings and side walls of wells. It prefers to live in those places of towns and cities which have plenty of coarse grains. Thus, their favourite resorts include big buildings, godowns, grain markets, temples, mosques, churches, tombs, railway stations and office buildings. They never nest on trees.

Nature:

The pigeons are inoffensive, harmless, timid and gregarious birds. During breeding season solitary couples make a simple, flat and artless nest of small sticks and thin roots, etc., at all sorts of places where there is some shelter from rain and sun. The eggs are laid in these nests and further development also occurs there. During winter, the pigeons collect into flocks which may be composed of several hundred individuals.

Food and Feeding:

The pigeons are vegetarians, feeding on grains, pulses, seeds of fruits and grasses. Sometimes they feed on insects, snails and slugs probably mistaken for seeds. They regularly leave their places of retreats and settlings during mornings and evenings, and collect into flocks to plunder the nearby fields.

Locomotion:

The pigeons are provided with long powerful wings which are well adapted for swift and strong flight. They walk on their two legs and such kind of walking is called bipedal gait. They walk on ground in search of food with great rapidity. When startled, they rise suddenly by striking the ground with their wings producing a crackling sound.

Sound:

The pigeons do not sing, chirp or screech but produce a characteristic sound which resembles the syllables gootur-goon, gootur-goon.

Family Life:

They lead a monogamous life, i.e., one male lives and copulates with only one female throughout the life.

ADVERTISEMENTS:

Reproduction and Incubation:

The internal fertilisation is performed by copulation in which temporary union of male and female takes place at their cloacal ends, i.e., cloacae of the two oppose each other, and transfer of sperms occurs directly into the urodaeum of female. The pigeons are oviparous, the eggs are laid in the nest and are incubated by the warmth of the parent’s body and hatching occurs after a fortnight.

Parental Care:

The newly hatched youngs are immature, helpless and featherless and are nourished by both parents by a fatty, curdy secretion, the pigeon’s milk, which is secreted in their crop. The parental care and homing instinct are well developed in pigeons.

Distribution:

The Blue Rock Pigeons are widely distributed in Palaearctic (Europe) and Oriental regions (Asia) and North Africa. They are especially plentiful in Palestine city of Israel. In India, two subspecies of Columba livia are namely, Columba livia neglecta is found up to 13,000 feet on the Himalaya.

Another Columba livia intermedia is smaller and darker race, which occurs throughout India. The Indian wild pigeon differs from that of European in having the rump or lower part of the back ash-coloured, while Indian pigeon is white.

When Pigeons Flock, Who’s in Command?

When Pigeons Flock, Who’s in Command?

That flock of pigeons flying overhead may look like a chaotic cloud of birds, but it’s more like an airborne hierarchy. By strapping tiny global positioning system (GPS) backpacks onto the birds, researchers have found that a flock follows several leaders at any given time in flight. But the flock’s leadership can change so that even low-ranking birds sometimes get a chance to command. The findings could shed light on how other groups of animals behave en masse, such as herds of wildebeest, schools of fish, and even crowds of humans.

Flocks of birds are one of the most common sights in everyday life, but many aspects of the animals’ behavior remain poorly understood. Why, for example, do flocks suddenly change directions and then change directions again within a few seconds? Why do birds in flight suddenly stop to rest on a certain stretch of telephone wire? And lacking any threat or sudden disturbance, why do flocks on the ground spontaneously take to the air?

To find some of the answers, researchers exploited a bit of 21st century technology. A team lead by statistical physicist Tamás Vicsek of Eötvös University in Hungary outfitted a trained flock of 13 homing pigeons with tiny GPS receivers that could determine each individual bird’s position every 0.2 seconds. Then they sent as many as 10 members of the flock out on 15 test flights. The journeys included four flights of about 15 kilometers back to the birds’ roost and 11 flights roaming freely around their home base outside Budapest. The researchers tracked each bird’s directional changes and how often those changes either followed or were copied by its flockmates.

In today’s issue of Nature, the team reports that the flight patterns showed a definite hierarchy, with most or all of the birds consistently copying changes in direction by the flock’s leaders, which almost always flew in front. If, for example, a leading bird suddenly swerved to the right, its followers copied its move within about 0.4 seconds—an amount of time considered too long to be reflexive.

However, the data also revealed that the leaders weren’t always the same, even within a single flight. And sometimes, even the birds at the bottom of the pecking order would lead the flock for brief periods. The arrangement made each flight more egalitarian, but the researchers think the reason might be more evolutionarily than politically driven. It’s possible that this type of group decision-making is more accurate or beneficial than others, says zoologist and co-author Dora Biro of the University of Oxford in the United Kingdom. Perhaps the individuals in the flocks stand a better chance of survival if they sometimes participate in guiding the group rather than constantly submitting to a single leader, she says.

Another curiosity was that the lower-ranking birds most often flew behind and to the right of the leaders. The researchers think this relates to the structure of the birds’ brains, in which the left side handles spatial tasks and the right side governs social recognition. Therefore, anything the birds see with their left eye (which is processed by the right side of the brain) tends to yield a quicker social response.

The findings could help explain group behavior of other animals, such as schooling fish, says evolutionary biologist Iain Couzin of Princeton University. There’s a “fascinating balance” between democratic and hierarchical control in the pigeon flocks, he says. And this sophisticated study reveals the link between the birds’ brain hemispheres and how they gather information during their flights. It achieves “a deeper understanding of coordinated control in animal groups,” he says.
