GPS backpacks identify leaders among flocking pigeons

GPS backpacks identify leaders among flocking pigeons

A freewheeling flock of birds is one of nature’s most endearing spectacles. The flock’s members move with uncanny coordination, changing direction in unison, splitting and reforming, and even landing as one. The intricacies of these synchronised flights are very difficult to entangle. Who is following whom? Is there even a leader and, if so, does the same bird always take up pole position? Our feeble eyes could never hope to discern the answers just by watching a flying flock. But fortunately, we have technology that can do the job for us.

, Budapest, has found that flying pigeons obey strict chains of command, even when in flight. He used state-of-the-art GPS devices to track the movements of groups of ten pigeons with exquisite sensitivity. The lightweight monitors, just 16g in weight, captured the subtleties of the pigeons’ twists and turns in mere fractions of a second. Back on the ground, Nagy analysed their recordings to show that pigeons fly according to the pecking orders they establish on the ground. The dominant bird takes the lead and the others follow his directions. Studying the collective movements of animal groups has been a difficult challenge. Many cameras can be used to film animals moving within the same block of space, but the jostling bodies often block one another from view. Mathematical models can tell us about the basic rules that groups of moving animals adhere to, but they are difficult to test in real life. But our technology has now become advanced enough to start skirting around these problems. For scientists studying birds, the key breakthrough was the creation of sensors that are light enough to be strapped to a flying bird without compromising its aerial abilities. Now, these sensors include GPS devices that can record a bird’s speed and direction every fifth of a second. Nagy attached such devices to 13 homing pigeons and watched as they flew in flocks of 7 to 11 birds.

Nagy catalogued every instance when one pigeon changed direction only to be followed by another. By pooling together this data, he created a network of leaders and followers, showing the relationship of each bird to its peers. This colourful diagram shows one such network. Each circle represents an individual pigeon, the arrows point from a leading bird to one that follows it, and the numbers represent the time delay between the leader’s movements and those of its follower’s. The networks showed that flocking pigeons maintain a dependable hierarchy on the wing. On average, when a leading bird changed direction, its followers would follow suit after around a third of a second. Birds will consistently copy the movements of specific individuals further up the pecking order and, in turn, they are consistently copied by more junior underlings. What makes a leading pigeon? It seems that skill counts for something. Nagy released each of his birds on a solo flight, some distance from home. When they returned, he found that those who arrived home quickest were also most likely to wield leadership authority, although this link between navigation ability and seniority wasn’t quite statistically significant. Indeed, the chains of seniority within pigeon flocks are fairly flexible, changing dynamically from flight to flight. Influential birds tend to remain influential but Tamas Vicsek, who led the study, says, “There are days when the pigeon which takes the role most of the time is less active. Perhaps it did not have a good sleep! During these days some of the birds on lower levels of the hierarchy have their chance to lead.” Nagy’s data also revealed that leaders do indeed take up pole position at the front of the flock. That may seem intuitively obvious to us, but remember that pigeons have a field of vision that extends for almost a full 360 degrees. When you can easily see individuals flying behind you, the leading bird doesn’t necessarily need to be at the front, and yet it does. More surprisingly, leaders also tend to stay on the left of the flock. Nagy found that the more time that a bird spent behind a leading partner, the more likely it was to be flying on that partner’s right. There’s an obvious reason for this – like us, pigeons have highly asymmetric brains with each half wielding greater influence over certain thought processes. Their right brain, which receives signals from the left eye, controls the ability to recognise other pigeons. So if a pigeon sees one of its peers through its left eye, rather than its right, it responds more quickly or more strongly.

Pigeons – Rock Dove

Pigeons – Rock Dove

Commonly known as Pigeons, Rock Pigeons are often considered a nuisance by some city officials and some farm businesses.

In cities they congregate in large flocks and can create messes with their droppings.

On farms, eating grains and possible harm to livestock through bacteria and viruses are concerns about these birds.

Many pigeon deterents are available online to prevent nesting in areas they’re not wanted.

Introduced into North America from Europe in the 1600’s, these birds have been associated with humans for thousands of years.

Rock Doves are thought to have been the first domesticated bird, raised for meat as far back as the time of the ancient Egyptians.

Description

Pigeons have different colors due to breeding by humans. They are the descendants of the wild Rock Dove of Europe.

About 13 inches in length with a dark gray head, iridescent neck, with a light gray back and 2 dark wing bars.

Mating – Breeding Habits

Like Mourning Doves, pairs are monogamous, often breeding in consecutive seasons for as long as both birds of a pair live.

Most will attempt to raise several broods each year. Sometimes as many as four or five broods will be raised in a single year.

The breeding season of these birds can be all year provided climate conditions allow. There seems to be some slowing down during the winter months.

Nesting Habits

The nesting habits of Pigeons are a bit unique. The male chooses a site in view of the female, selecting one stick and bringing it back, lays it in front of his mate.

The female who stays at the nesting site accepts the sticks the male brings to her and places them underneath her.

The nest of these birds can be found along building ledges, rafters, beams, under bridges or inside barns.

The nest is saucer-like in shape and made of stems and leaves.

The female may sit on the nest a day or two before the first egg is laid. Generally 2 white eggs are laid.

Both the male and female will incubate but the female will spend the most time on the eggs since she will be on the nest from mid-afternoon to mid-morning.

Incubation last for about 18 days. When the eggs hatch the young are covered in yellow down.

Young pigeons in the nest are referred to as “squabs”

Initially, the squabs are fed what is referred to as crop milk. This is a regurgitated thick liquid food that comes from the parents crops.

At about 10 days the squabs are fed increasing amounts of the food types that adults eat and are no longer dependent on crop milk.

The young will double in size in a day and a half. Making them one of the fastest growing vertebrate in the world.

Within 2 weeks the flight feathers begin to emerge and by week 3 the squabs are covered in feathers.

The tail and full feathering is completed by the 28th day and their weight is that of an adult.

The young will now leave the nest and the male will teach them what they need to know to survive.

This is 10 – 15 days longer than most of our backyard birds.

The female will begin a new clutch and this cycle will repeat about every 30 days when weather cooperates.

Do Pigeons Reuse the Same Nest

It’s more accurate to say that the same nest site is used as the second and subsequent nest are built on top of the previous nest.

Nest that are several years old can measure out to be as much as 7 inches high and 19 inches wide.

Feeding Habits – What Pigeons Eat

Rock Pigeons feed on the ground. To prevent seed spoilage and to keep the birds healthy a ground feeder is recommended for all ground feeding birds.

The best types of food to offer these birds are properly mixed seeds specifically made for doves and pigeons.

Predators

The primary preadators of pigeons include: man, peregrin falcon, and cats. Nest predators include oppossums, raccoons, crows and owls. Hawks will capture perching birds.

Are Pigeons Smart Birds?

According to Professor Richard J. Herrnstein at the Harvard Psychological Laboratories they are. Pigeons were smart enough to learn all the letters of the english alphabet.

In another study, Pigeons were able to recognize themselves in a mirror. This makes them one of six species and the only non-mammal to be able to do so.

So yes, Pigeons are a pretty smart bird.

What is the Lifespan of Pigeons?

Pigeons may live 3 – 6 years in the wild with the average being 3 – 4 years. In captivity they have lived as long as 15 years depending on the care given to the bird.

Pigeons in History

During the world wars, Homing Pigeons were trained to return to a loft in the UK.

Troops then took the pigeons with them and used them to send messages when radio and written communication were being intercepted.

Pigeon Fun Facts

Pigeons have the ability to see about 26 miles.

When fully feather, adult pigeons have around 10,000 feathers.

There are approximately 400 million pigeons in the world.

Well-fed pigeons leave their mark at Lawrence and Markham

Well-fed pigeons leave their mark at Lawrence and Markham

One of the best places for pigeons is at Markham Rd. and Lawrence Ave., where a perpetual buffet of birdie num num is on the menu.

It is also a bad place to be a pedestrian or a TTC rider. After they dine, the birds roost on overhead utility wires to digest their meal and then deposit wet, smelly droppings on the sidewalk and people below.

We’ve had several complaints over the past few years about the hundreds of pigeons drawn to the southwest corner of the busy intersection by food scattered across a parking lot.

The bird lovers’ hearts are in the right place, but the mess created by the huge number of pigeons attracted to the food is the bane of people who catch the bus at a TTC stop on the corner.

A reader told us he’s been twice bombed on his way to the TTC stop, adding that he’s heard it’s a sign of good luck to be pooped on by a bird but doesn’t believe it.

“They sit on the wires and s– on everything below,” said the reader, who asked not to be named. “One time I could see it falling in front of me, like it was raining bird s–.”

We’ve gone there several times and seen hundreds of pigeons and a few seagulls pecking at seed in the parking lot, while others that had finished dining roosted wing-to-wing on wires on the east side of Lawrence, waiting to drop a surprise on a hapless victim.

The sidewalk below the wires had a residue of guano on it, but we thought it would have been much worse. Plentiful rainfall over the past few weeks has likely washed away some of it.

Dumped next to a concrete barrier on the north side of the parking lot was a huge pile of stale white bread cut into pieces — enough to fill a couple big garbage bags — along with several pounds of white rice.

The situation raises a couple questions, like who’s doing it and what can be done, if anything, to stop them.

STATUS: We asked the city if any rules prohibit the feeding of birds. City spokesperson Angelica Santos sent us an email that said “feeding wildlife can increase the population of wild animals in a community and cause the animal to lose its natural fear of people.” Yeah, but we’re talking about pigeons, not raccoons or bears. Santos went on to cite bylaws that say “a person feeding wildlife in a public area can be fined by the city, if the person is observed by an officer throwing waste.” In other words, unless a bylaw enforcement officer stakes out the parking lot and catches someone feeding them, there are no repercussions. We also found a page on the city’s website that says “there are no specific bylaws that restrict the feeding of wildlife outside of a city park.” Since the feeding is done in a private parking lot, it looks the feeders are home free.

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.

Police in India take pigeon into custody after bird found with note threatening PM

Police in India took a pigeon into custody Monday after the bird was found carrying a warning note to the country’s Prime Minister Narendra Modi.

According to Agence France-Presse (AFP) news agency, Border Security Force (BSF) officers found the pigeon in the northern state of Punjab, where clashes between Indian and Pakistani troops have intensified.

“We took it into custody last evening,” a police investigator told the news agency. “The BSF found it with a note in Urdu saying something like ‘Modi, we’re not the same people from 1971. Now each and every child is ready to fight against India’.”

The note was apparently signed by the banned Pakistani militant group Lashkar-e-Taiba.

According to English language newspaper The Indian Express, this is the second time in just over a week a pigeon has been found with some sort of note apparently sent from Pakistan.

On Sept. 23, a bird was found in Hoshiarpur district with “some words written in Urdu,” the newspaper reported.

“We are investigating the matter,” inspector Ramesh Kumar told the Express.

The effect of habitat and number of inhabitants on the population sizes of feral pigeons around towns in northern Poland

The effect of habitat and number of inhabitants on the population sizes of feral pigeons around towns in northern Poland

Most studies on factors influencing density of the feral pigeons Columba livia var. domestica were carried out in large cities and agglomerations. However, also in small towns, pigeons are important epidemiological and sanitary problem. In our studies, feral pigeons were censused in 33 towns located in the Pomeranian Province (northern Poland) during 2006–2008. These birds occurred in 19 (57.6%) towns. The number of pigeons was positively correlated with the area of the town, and it was significantly higher in towns localized in agricultural landscape than in towns surrounded by forests. We also found a significant effect of interactions between type of a landscape surrounding a town and residual number of inhabitants on the abundance of pigeons. In the largest towns of the Pomeranian Province, feral pigeons were concentrated mainly in central quarters. In smaller towns, they were noted in central parts or in areas with blocks of flats and even the suburbs. The obtained results suggest that food conditions in small and middle towns may be not sufficient for colonization by pigeons.
