Pigeons’ navigation skill not down to iron-rich beak cells: study

Pigeons’ navigation skill not down to iron-rich beak cells: study

The theory that pigeons’ famous skill at navigation is down to iron-rich nerve cells in their beaks has been disproved by a new study published in Nature.

The study shows that iron-rich cells in the pigeon beak are in fact specialised white blood cells, called macrophages. This finding, which shatters the established dogma, puts the field back on course as the search for magnetic cells continues.

“The mystery of how animals detect magnetic fields has just got more mysterious” said Dr David Keays who led the study.

Dr Keays continued: “We had hoped to find magnetic nerve cells, but unexpectedly we found thousands of macrophages, each filled with tiny balls of iron.”

Macrophages are a type of white blood cell that play a vital role in defending against infection and re-cycling iron from red blood cells. They’re unlikely to be involved in magnetic sensing as they are not excitable cells and cannot produce electrical signals which could be registered by neurons and therefore influence the pigeon’s behaviour.

Dr Keays’s lab, based at the Institute of Molecular Pathology in Vienna, worked together with Dr Shaw from the University of Western Australia, and Drs Lythgoe and Riegler from the UCL Centre for Advanced Biomedical Imaging in London.

“We employed state-of-the-art imaging techniques to visualise and map the location of iron-filled cells in the pigeon beak” said Dr Mark Lythgoe.

The search for the actual mechanism that allows migratory birds, and many other animals, to respond to the Earth’s magnetic field and navigate around their environment remains an intriguing puzzle to be solved.

“We have no idea how big the puzzle is or what the picture looks like, but today we’ve been able to remove those pieces that just didn’t fit,” said Dr Keays.

Pigeons identify individual humans but show no sign of recognizing them in photographs

Pigeons identify individual humans but show no sign of recognizing them in photographs

Photographs, especially of humans, are widely used as stimuli in behavioural research with pigeons. Despite their abundant use, it is not clear to what extent pigeons perceive photographs as representing three-dimensional objects. To address this question, we trained 16 pigeons to identify individual, real-life humans. This discrimination depended primarily on visual cues from the heads of the persons. Subsequently, the pigeons were shown photographs of these individuals to test for transfer to a two-dimensional representation. Successful identification of a three-dimensional person did not facilitate learning of the corresponding photographs. These results demonstrate limitations of cross-recognition of complex objects and their photographs in pigeons.

Pigeon fancier facts

Pigeon fancier facts

Belgium is regarded as the home of pigeon racing, with approximately 60,000 pigeon fanciers in a population of 10 million.

In a standard race, as many as 5,000 tagged pigeons are transported to a single location and released.

When the pigeon arrives home his owner removes the tag and gets it time-stamped by a sealed timing device, designed so that it cannot be tampered with.

Homing pigeons have a long and distinguished history. In 1815, a pigeon belonging to the financier Nathan Rothschild carried the news of Napoleon’s defeat at Waterloo to London.

A homing pigeon belonging to the US Army Signal Corps in 1918 was awarded the French Croix de Guerre. The bird, named Cher Ami, is currently mounted in the Smithsonian’s Price of Freedom exhibit in the US.

According to Tucker Daniel, and his fellow enthusiast Kevin Barry, some pigeon fanciers of note include footballer Duncan Ferguson, actor Paul Newman and boxer Mike Tyson. (Iron Mike? Really?) For more information see www.racingpigeon.ie or www.isrf.ie

Pigeon poop proves a problem. Police involved

Pigeon poop proves a problem. Police involved

There’s been a few charges laid around town but there is one individual who is causing more headaches than normal

The pigeon problem in Kirkland Lake is so bad, police felt the need to issue a news release this morning warning residents to follow the law when dealing with them.

The town started renting out traps to residents today to capture pigeons, and police say that trappers will be responsible for the disposal of the birds, which includes a ban on throwing them in the garbage for curbside pickup. Successful trappers will instead have to take the pigeons for burial at the town dump.

“The OPP want to inform the residents that it is each individual’s responsibility to educate themselves on this topic and to ensure that they are acting within the laws, regulations and town by-laws,” says Constable Adam Gauthier.

The problem started, says Ashley Bilodeau, Kirkland Lake’s Manager of Planning and Land Development, when a few bird lovers started feeding the pigeons.

“We have a couple of residents that have been obnoxiously feeding pigeons to the point where we have some serious problem areas, so we passed a no-feeding bylaw back in the fall,” she told BayToday. “However, there is one individual who just continues to feed them despite the bylaw and has been charged. There’s been a few charges laid around town but there is one individual who is causing more headaches than normal.”

The fine for feeding is steep at $100, and that’s down from the $250 the town wanted to charge but the province wouldn’t allow it.

“So we’re trying to find different ways to combat the issue because it’s now causing problems to people’s properties and vehicles because there are so many of them.”

Bilodeau says the town has checked with the MNRF and it’s not illegal to kill pigeons although you are required to have a small game licence in order to trap and kill pigeons.

The town has not placed a limit on the number of pigeons people can capture, but police warn folks can’t use their guns to shoot the birds because discharging a firearm is prohibited within the Town of Kirkland Lake,

Bilodeau says poop is the problem.

“They’re also causing damage to buildings by trying to build nesting areas,” she adds. “We’ve got four traps here and people can come in and put in a deposit and take the trap for 10 days, and when they bring it back they get their money back.”

Pigeons were originally bred from the wild rock dove, which naturally inhabits sea-cliffs and mountains according to Wikipedia, so the bird finds the ledges of buildings to be a substitute for sea cliffs.

They have become abundant in towns and cities throughout the world. Due to their abilities to create large amounts of excrement and to carry disease, combined with crop and property damage, pigeons are largely considered a nuisance with steps being taken in many municipalities to lower their numbers or completely eradicate them.

Cher Ami: The Pigeon that Saved the Lost Battalion

Cher Ami: The Pigeon that Saved the Lost Battalion

Many of us have heard of the Lost Battalion, and know some of the story. What is not commonly known is the role of a remarkable pigeon, named Cher Ami. That little bird became one of the greatest heroes of World War I.

Cher Ami was one of almost 600 carrier pigeons employed by the US Army Signal Corps during the First World War. Carrier pigeons were invaluable , in spite of the advances in communications technology during the war. Radios were not as reliable since they were large and still bound by delicate wires. It also was not always possible to lay new wires quickly, and often could be extremely dangerous. While not necessarily a popular form of communication, pigeons did prove a reliable one. The average homing pigeon can fly approximately fifty miles per hour, making them a quick method of communication. Still, these pigeons often proved popular targets to enemy gunfire despite their speed. In fact, German machine gunners trained diligently to both spot and kill these birds with their deadly MG 08s, which could fire over 500 rounds per minute. Pigeons could also be a very risky way to communicate, because if a pigeon was shot down, the message could easily be intercepted by enemy forces.
The US Army Signal Corps used some 600 pigeons in WW1.
It was during the Meuse-Argonne Offensive of 1918 where the carrier pigeon was finally recognized for its valiant efforts. On October 2nd, 1918, American soldiers from the 77th Division pushed too far into the Argonne Forest and became trapped behind German lines on the slopes of a hill. Cut off from reinforcements and supplies, roughly 550 men from the 306th, 307th, and 308th regiments under Major Charles Whittlesey held their ground against a far larger German force for several days. Far beyond radio range, the only way the Americans could communicate with their own lines was via carrier pigeon. However, it did not take long to realize that the skies were as dangerous as the ground. Trapped in a horrible meatgrinder of machine guns and rain, the Lost Battalion held their ground against vicious German attacks.
On October 4th, American heavy artillery started to bombard the Lost Battalion’s position on accident, killing thirty men as they held the line. Major Whittlesey and his men watched as bird after bird fell out of a sky torn apart by German fire. With supplies running out and casualties mounting rapidly, Major Whittlesey desperately sent out his last pigeon, Cher Ami, to the American lines with a note that simply read, “We are along the road parallel to 276.4. Our own artillery is dropping a barrage directly on us. For heaven’s sake, stop it.” With fire raining down on them from all sides, Cher Ami was now the last chance for the Lost Battalion to walk off that hill alive.
Capt John Carney, Cher Ami’s trainer, holds the feathered hero.
The brave bird flew straight into the German fire, dodging bullets as he went. However, his luck did not last for long. Cher Ami was hit in the chest soon after takeoff, as American soldiers watched in horror as their last hope hit the ground. Against all odds though, Cher Ami got up again! Wounded but still alive, the little bird took flight again, charging head-on into wave after wave of gunfire. By the end of the trip, he covered 25 miles in roughly half an hour. He arrived at base heavily wounded, but alive.
The Croix de Guerre with Palm military decoration of France, awarded to Cher Ami.
Army medics were able to save Cher Ami’s life, but his right leg was barely attached to his body and he was blind in one eye. However, because of Cher Ami’s delivery, the artillery stopped and took up new firing coordinates away from American lines. The next day, shells started to fall on German positions, relieving pressure on the bloodied 77th and the battle turned in America’s favor. On October 8th, one hundred and ninety-four men made it back to the American lines thanks to Cher Ami’s sacrifice.
For his part in saving the 77th Division, Cher Ami was awarded the Croix de Guerre, one of France’s highest military honors for his gallantry in the field. General John Pershing, commander of the American Expeditionary Force, said “There isn’t anything the United States can do too much for this bird.”
Cher Ami made it back to the United States in the care of its trainer, Capt John Carney.  On June 13th, 1919, Cher Ami died at Fort Monmouth, New Jersey. However, Cher Ami’s body was preserved and presented to the American Government with honor. It is difficult to say how many families owe their existence to the sheer courage and self-sacrifice of one brave bird. Today, Cher Ami is on display at the Smithsonian Museum of American History to preserve his memory. Since then, his story has lived on in the hearts and minds of Americans across the decades, and his bravery will never be forgotten.

Why Pigeons Are On Your Roof

Why Pigeons Are On Your Roof

Bird control technicians’ nightmare – what to do when we are asked to do the impossible? The straight answer is that there is really nothing we can do when pigeons land on your roof, but there is much more to know.

Many customers ask: “Why? Why my roof, what’s so special about my roof that they have to land there?” Believe it or not you are asking the right question: Why? Once you understand why, you will also understand why is it hard to provide a solution in this situation.

Almost always, the primary cause of such problem is the availability of food nearby, plenty of it on a regular basis. Probably someone is feeding the birds or there are lots of garbage in the area or open garbage bins/containers. They could also nest or roost in close proximity and simply they use your roof as a comfy perching spot having a nice vantage point over their feeding area.

What could we do? Install hundreds of feet of spikes on your roof? Put up scary owls? Maybe speakers on the roof peak? Unfortunately none of them are viable. It is simply not feasible to protect large, flat (horizontal or sloped) roof surfaces, such as the entire roof of a victorian house for example.

Feeding pigeons.

Lady feeding the pigeons in College Park – every day.

First, we need to find ways of eliminating food and water sources nearby. Then we must find their nesting/roosting areas – which will most likely be on another property, otherwise you would see them somewhere else on your house/building, (in which case it would be very easy to resolve the issue,– that provides sheltered structural configurations to establish a protected area where they can stay at night. Pigeons don’t see well at night and usually they go to their roosting spots before nightfall and stay there during the night.

If protecting these areas are not possible (because they are on someone else’s property) we can look at strategically installing Bird Spikes or exclusion Bird Netting or the combination of both, maybe Electric Tracks at critical areas to discourage them from landing on your roof.

You can see now that there aren’t any straightforward solutions in the case of house roof tops and that it is very time consuming to address the issue holistically. The best thing you can do is to call up a professional and get an opinion, you might have missed something that a pro will notice that could help resolve the issue.

Some other options for bird repellent would be the Ultrasonic Sound Repellent which makes noises that can only be heard by pigeons and scare them off with the sound or the laser beam which can be activated by movement or you can time when these lasers come on. These lasers are too strong for the pigeons vision to handle and they will fly elsewhere. You can purchase these here : https://www.pigeonpatrol.ca/product/laser/
