For thousands of years, humans have bred rock doves (a.k.a. pigeons) to travel home over massive distances. These domesticated pigeons have helped us fight wars, find shipwrecks, and deliver blood samples. But despite our long partnership, we have yet to understand exactly how they navigate hundreds of miles back to their roost. New research shows that they may, in part, be sniffing their way home.

To navigate, scientists believe that birds use both a map and a compass. The compass—the sun or the Earth’s magnetic field—tells pigeons where, say, south is. The map, which tells them home is south, could come from odors carried on winds around a pigeon’s home perch, reports German ornithologist Hans Wallraff, of the Max Planck Institute for Ornithology, in the journal Biogeosciences.

Earlier research revealed that impairing a pigeon’s sense of smell disorients the bird so that they cannot return to their home site. Wallraff’s meticulous study of air samples surrounding a pigeons’ roost suggests that odors offer consistent location cues. He believes that this can allow birds to learn to associate a given direction with a scent. So when they’re traveling and detect a certain odor—whether the sharp scent of seawater, ripe reek of the local dump, or mouth-watering aroma of a bakery—they build a mental map of the area using their olfactory memories.

In fact, the scent trail may be so strong that pigeons can navigate by it alone, Wallraff’s new model shows. Wallraff input data from his previous air sampling work, which included 46 odorous chemical compounds from 96 sites surrounding the pigeons’ home. He then modeled whether virtual birds could learn to navigate using these odoriferous signals. He found that over evolutionary time, birds become more sensitive to scents and can in fact use these pungent clues to travel home.

Although he has yet to determine which odorous chemical clues are most important, Wallraff’s findings reveal how avian olfaction may enable a bird to successfully traverse more than 1,000 miles, which is nothing to sniff at.

How birds find food

by Pigeon Patrol | Aug 9, 2021 | Bird Spikes, Columbidae, Doves, history of pigeons, MBCA, pet bird, Pigeon Control

DEAR JOAN: Yesterday afternoon I blew the leaves off the lawn and garden in my backyard, leaving a lot of bare soil showing. A couple of hours later, I happened to look outside and to my wondering eyes there appeared a dozen beautiful little robins, pecking away all over the yard.

I must have unearthed grubs or something edible, but how did they know that? They stayed an hour, then took off together. What a delight.

Earlier in the week I awoke at 3 a.m. to the smell of a skunk in my front yard. I live in a neighborhood of small houses, all with the fenced yards. I never cease to wonder how these wild creatures manage to get around and find food.

DEAR DOROTHY: Birds have such supercharged metabolisms that when they are active, they pretty much have to eat constantly to maintain their energy. As a result, birds are exceptionally good at finding food.

They do this not by scent — with very few exceptions, birds have a rotten sense of smell — but by sight and sound.

As they fly and flit around, they are scoping out the landscape. They may spot a bird feeder, a bush full of berries, or a cleared patch of dirt. They may not recognize it as such, but they see the changes in the landscape and drop down to explore.

Birds have amazing little brains and memories, so the robins probably noticed something had changed in your yard, and that all that dirt was holding a feast.

Birds also listen to the calls and coos of other birds, which can tip them off about a source of food.

American robins eat a variety of foods, but they certainly love nice juicy worms, and they are most adept at finding them.

Folks used to believe the robins could hear the worms crawling about beneath the soil, but researchers have found that it’s just experience. They know where worms likely are, and they hunt them out, not unlike me and frozen yogurt shops.

As for the skunks and other critters, they too are driven by the need for food and water, and they are undeterred by urban fences.

Mating season for skunks usually begins in February, but I’m already seeing a lot of skunks out and about, and unfortunately, dead on the roads, so I think they might be getting an early start this year. Just a reminder that the males use their scent to attract females, so we will be smelling that pungent aroma a lot in the coming weeks.

Hero Dog awards

The American Humane Association, a national organization that works to improve the lives of both animals and children, has launched its annual Hero Dog awards to recognize the country’s bravest heroes on both ends of the leash.

The awards are divided into eight categories — therapy, service, law enforcement, military, arson, search and rescue, guide/hearing and “emerging hero” dogs, which pays tribute to ordinary dogs that do extraordinary things.

Winners in each category will be treated to a Los Angeles gala awards ceremony in September, where one of the finalists will be named top dog.

Pigeons Are Secretly Brilliant Birds That Understand Space and Time, Study Finds

by Pigeon Patrol | Aug 3, 2021 | pet bird, Pigeon Control, Pigeon Droppings, Pigeon Patrol's Services, Pigeon Predators

Of all the birds in the world, the pigeon draws the most ire. Despite their reputation as brainless “rats with wings,” though, they’re actually pretty brilliant (and beautiful) animals. A new study adds more evidence that the family of birds known as pigeons are some of the smartest birds around, as Quartz alerts us.

In addition to being able to distinguish English vocabulary from nonsense words, spot cancer, and tell a Monet from a Picasso, pigeons can understand abstract concepts like space and time, according to the new study published in Current Biology. Their brains just do it in a slightly different way than humans’ do.

Researchers at the University of Iowa set up an experiment where they showed pigeons a computer screen featuring a static horizontal line. The birds were supposed to evaluate the length of the line (either 6 centimeters or 24 centimeters) or the amount of time they saw it (either 2 or 8 seconds). The birds perceived “the longer lines to have longer duration, and lines longer in duration to also be longer in length,” according to a press release. This suggests that the concepts are processed in the same region of the brain—as they are in the brains of humans and other primates.

But that abstract thinking doesn’t occur in the same way in bird brains as it does in ours. In humans, perceiving space and time is linked to a region of the brain called the parietal cortex, which the pigeon brains lack entirely. So their brains have to have some other way of processing the concepts.

The study didn’t determine how, exactly, pigeons achieve this cognitive feat, but it’s clear that some other aspect of the central nervous system must be controlling it. That also opens up the possibility that other non-mammal animals can perceive space and time, too, expanding how we think of other animals’ cognitive capabilities.

Homing Pigeons are Forgetful Too

If it makes you feel any better, humans aren’t the only animals that forget things. Researchers have found that homing pigeons do the same. The new findings, they add, suggest an underlying continuity across the human and animal world in how the brain works.

The knack of remembering and forgetting is the brain’s way of filtering information to manage its limited storage capacity. For example, you briefly store information about trees and cars around you in your working memory, but if someone tells you to focus on a speeding truck, your brain uses a process called executive control to remember that object longer. Meanwhile, you forget the others. In humans, this filtering is performed by the prefrontal cortex.

To test whether the avian brain has a similar filtering mechanism, Michael Colombo, a neuroscientist at the University of Otago, New Zealand, and colleagues subjected homing pigeons to a memory test. First, the researchers trained the birds to know that a high tone means they should remember an object, while a low tone means they can forget it. They then showed the birds one of two shapes (circles or dots) or colors (blue and green). After a bird pecked three times at the image, the researchers sounded a tone. Birds that heard the remember cue fired up neurons in a region of their brain analogous to the human prefrontal cortex (as measured via implanted electrodes), Colombo’s team reports today in PLos Biology. And those birds did, in fact, remember the objects: 79% of the time, they correctly pecked at the original object again when shown multiple images 3 seconds later. In contrast, birds that heard the forget cue did not exhibit sustained activation of the same brain area, and only in about 44% of cases did the birds correctly identify the original object. Thus, the researchers argue the birds use a similar mechanism as humans to filter their memories.

Birmingham pigeon fanciers inspire play

by Pigeon Patrol | Jul 27, 2021 | pet bird, Pigeon Control, Pigeon Droppings, Pigeon Patrol's Services, Pigeon Predators

Pigeon fanciers in Birmingham have provided the inspiration for a new play, which the team behind it plan to stage at a city pigeon loft.

The play is written by Mandy Ross and based on an idea by Alex Lockett.

Artist and curator Alex Lockett said the play has developed from a project to chronicle the lives and stories behind a hidden passion in the city.

She said she had become “hooked” herself a little more than four years ago.

“Project Pigeon started as an arts event. I went along to a pigeon club and all these guys were telling me some amazing stories,” she said.

“I went from knowing nothing to keeping about 50 or 60 birds in a loft in Digbeth.”

Pigeons on trains

In January of this year Project Pigeon was awarded a £43,000 grant from the Heritage Lottery Fund to compile an archive of pigeon fancying in the city.

More than 30 audio interviews and a dozen videos later the archive is almost complete.

It is due to be handed over to Birmingham Library next year, with some of the stories also going to Bletchley Park’s Animals at War exhibition.

Ms Lockett said pigeon fancying had become more popular in the West Midlands than any other region in the country, with its popularity in Birmingham driven by industrialisation and the development of the railways.

“People would take their pigeons down to New Street Station or Snow Hill and let them travel north or south.

“The railway stationmaster would later release them and the baskets would be sent back with the time of release attached to them. That happened right up until the 1960s.”

Today some of the best racing birds can be worth thousands of pounds.

Birmingham Roller

Ms Lockett said people were still passionate about the sport in the city but she had feared some of its social history might be lost.

“One guy had tables of every club race result from the last 30 years. You could see sons following fathers and the same names appearing at the bottom of the results.”

The city has even given its name to a breed of pigeon, known as the Birmingham Roller, bred not for speed but for its ability to perform somersaults in the air.

Fans of the bird include ex heavyweight boxer Mike Tyson, who has in the past bought birds from Birmingham and Wolverhampton breeders, in a bid to find a genuine Roller, Ms Lockett said.

Stories unearthed by Project Pigeon include that of Betty and Bernard Hemming who met and later married after Bernard struck up a friendship with her brother, a fellow pigeon fancier.

A murkier world was also revealed when one contributor revealed he had stolen a bird from a neighbour as a child and dyed it purple to prevent it being recognised.

The play, performed by Rogue Play Theatre, is due to be staged at Project Pigeon’s loft in Digbeth in April. A book is also being written and a series of radio plays, based on the interviews, are expected to be broadcast in February.

Messenger / Homing Pigeons & Their Applications

by Pigeon Patrol | Jul 19, 2021 | Bird Netting, Bird Spikes, Columbidae, Doves, pet bird, Pigeon Control

Homing pigeons are called messenger pigeons when they are used to carry messages. Messages have to be written on light, thin paper (such as cigarette paper) and rolled into a small tube that is attached to the bird’s leg. This is called “pigeon post.”

They have also been used to carry small light-weight packages, in including smuggling drugs into prisons.

RACING

In recent history, they are mainly used for the sport of pigeon racing. They have been bred for racing and can reach speeds between 60 – 80 miles per hour. They can fly up to 80 to 600 miles in one single day.

In 2010, Jose Ledesma’s pigeons finish a personal racing season in Canary Islands with amazing resultss. Two young birds raced 3 times each from African coast in Morocco. Long Distance Races + 1st Regional Price against 1312 pigeons (National race equivalent in Belgium). Jose made an amazing movie of these pigeons flying over mountains, seas and deserts: http://www.youtube.com/watch?v=IAGKflxwxwI … Further information can be found on his website: http://www.joseledesma.com/ – J. Ledesma, Tenerife – Canary Islands

THE CARRIER OF MESSAGES

During the Franco-Prussian War of 1870–1871, the Prussians had surrounded the city of Paris preventing mail from entering or leaving the city. During the course of the siege, pigeons and mail were regularly taken out of Paris by hot-air balloons. The letters that were sent to Paris were first reduced in size by photography, so that 30,000 letters could be carried on film placed inside a canister. These canisters were attached to pigeons and these birds then flew into Paris. Thirty-five birds carried the same letters, so that if any were shot down, at least one would reach Paris. In Paris, the film was projected on a screen, and the letters were copied by hand and delivered to homes in the city.

These birds have been used to transport short messages across long distances. In fact, historically well-known leaders, such as Julius Caesar and Genghis Khan, have used them to carry important messages across long distances.

One of the world’s best known news agencies, Reuters, started its European business by using 45 trained birds to carry financial news on the continent in 1850. They carried the latest news and stock prices from Aachen in Germany to Brussels in Belgium, travelling the 76 miles in a record-breaking two hours – beating the railway by four hours.

The Chinese used them to deliver mail as long ago as 1000 B.C.
