Homing pigeons reveal true magnetism

Homing pigeons reveal true magnetism

Iron crystals in their beaks give birds a nose for north.

It’s official: homing pigeons really can sense Earth’s magnetic field. An investigation of their ability to detect different magnetic fields shows that their impressive navigation skills almost certainly relies on tiny magnetic particles in their beaks.

The discovery seems to settle the question of how pigeons (Columba livia) have such an impressive ‘nose for north’. Some experts had previously suggested that the birds rely on different odour cues in the atmosphere to work out where they are. But the latest findings suggest that they are using magnetic cues.

The idea that pigeons’ beaks contain tiny particles of an iron oxide called magnetite is not a new one, says Cordula Mora, who led the latest study at the University of Auckland, New Zealand. But the particles themselves are likely to be only a few micrometres across, and no one has ever seen them under the microscope.

Mora’s behavioural experiments therefore give the best indication yet that pigeons are aware of Earth’s magnetic field. She and her colleagues taught the pigeons to discriminate between magnetic fields by placing them in a wooden tunnel with a feeder platform at either end and coils of wire around the outside.

Tunnel test

The pigeons were trained to go to one end of the tunnel if the coils were switched on, generating a magnetic field, and to the other if they were switched off, leaving Earth’s natural field unperturbed. “I was pleasantly surprised. The pigeons were very fast learners,” says Mora, now at the University of North Carolina in Chapel Hill.

Their skills were impaired, however, when the researchers attached magnets to their upper beaks, and also when the upper beak was anaesthetized. This suggests that their ability is down to the presence of magnetically sensitive material in this area, the researchers report in this week’s Nature1.

The team then set about seeing how these magnetic signals might be transmitted to the birds’ brains. When they severed the ophthalmic branch of the trigeminal nerve, which leads from the upper beak to the brain, the birds were unable to distinguish between natural and perturbed magnetic fields. But when the olfactory nerve, which carries smell signals, was cut instead, the birds performed fine, dealing a seemingly fatal blow to the idea that they navigate by relying on odours.

Nose for navigation

The results sit well with previous studies of another impressive navigator, the rainbow trout. The species both seem to have a system in which signals from magnetite particles are carried from the nose to the brain by the trigeminal nerve, says Mora. This is not surprising, she says, as iron-containing materials are common in many animals’ bodies.

So why has nobody seen the particles? Other researchers are looking for them, Mora says. But the problem is that even though we know where to look, they are elusive because of their small size and the fact that many other biological materials, such as blood, contain iron.

The particles are small because there’s no reason why they should be any larger, Mora adds. “You don’t need a large receptor structure like you do for the eye, because the magnetic field permeates everything,” she says. “It’s like a needle in a haystack.”

Tweeting Pigeons Now Reporting Pollution Levels Across London

Tweeting Pigeons Now Reporting Pollution Levels Across London

Last September, as part of Twitter’s #PoweredByTweets exhibition at Somerset House in the UK, a proposal called ‘Pigeon Patrol’ was presented. The idea was this: armed with pollution monitors in tiny backpacks, pigeons would Tweet live pollution data from the skies of London.

It seems a little far-fetched – I mean, a pigeon can’t actually tweet, obviously – but the concept was one of the standouts of the competition. And now, ‘Pigeon Patrol’ is officially live, with a team of flying pollution monitors at work, tweeting back data from around the city.

 

“Over the course of three days, Plume Labs (@Plume_Labs) and DigitasLBi (@DigitasLBi_UK) will release ten pigeons wearing small pollution-monitoring backpacks. These lightweight pollution sensors, created by Plume, are stitched onto small fabric vests which fit comfortably on the pigeons and measure levels of nitrogen dioxide and ozone, the main gases behind harmful urban air pollution.”

The idea is one of the more interesting and innovative ways of using Twitter data, and it underlines the capacity of the platform as a real-time news and update service. Pigeon Patrol was one of several ideas to spark new conversations around how Twitter can be used for such purpose – others included Guys and St Thomas’ Hospital, which created a chemotherapy ward with Tweet-powered visualizations and WaterAid, which developed a water pump that Tweeted donors with live updates of where their money was going.

It’s in that capacity for real, immediate updates that Twitter holds such great value and potential. And it’s not just in terms of world events and breaking news – the more intimate and geographically targeted Twitter alerts and tracking can be the better. We’ve already seen examples of how tweets can be used to better predict earthquakes or map the path of destruction from hurricanes. Imagine if you could use tweets to get a better understanding of local traffic concerns as they happen, to track petrol prices or supermarket offers nearby? These are relatively basic, by comparison, but the underlying principle is that Twitter’s real-time stream is extremely valuable for such purpose – more so than the algorithm defined News Feed of Facebook.

The main requirement for such application, of course, is Twitter use – more people using the platform means more data, which, again, is why Twitter’s current growth issues flag a concern for the ongoing viability of the service. Right now, Twitter’s used by enough people to be an indicative measure of most large-scale events. But micro-trends – those smaller, localized alerts – would require higher concentrations of local users in order to be effective. There are examples of this type of process in action – in Spain, the town of Jun is effectively governed via tweet, for example – and as the next generation of digital natives grows up, Twitter use is likely to become more prominent. But the issue does underline, once again, why Twitter needs more people tweeting, and why ongoing growth is such a big focus for the platform.

For now, we’ll have to settle for pollution tracking pigeons, flying around London in teams of 10 and tweeting back updates.

Pigeon poops on lawmaker discussing pigeon poop problem

Pigeon poops on lawmaker discussing pigeon poop problem

CHICAGO – A pigeon apparently didn’t think much of a lawmaker’s ideas to address a messy situation at a Chicago Transit Authority stop known by some as “pigeon poop station.”

WBBM-TV reports that one of the birds did its business on the head of Democratic state Rep. Jaime Andrade as he was discussing the problem with a reporter outside of the Irving Park Blue Line station.

During the interview, Andrade rubbed the top of his head and said, “I think they just got me.” They did.

The sidewalks outside of the station are covered in bird waste and feathers.

Andrade has been trying to fix the problem. One of his ideas is to ask the CTA to install a hose line for power washing when it constructs new escalators at the stop.

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.

Victoria resident catches, cleans pigeon feet to help fight stringfoot

Victoria resident catches, cleans pigeon feet to help fight stringfoot

Hair, string tangled around birds’ feet can cut off circulation to toes and whole feet

Pigeons with injured feet or missing toes are a common sight in downtown Victoria, says one resident who’s taken matters into her own hands by catching them and cleaning their feet.

Pippin Griffin carries around a collapsible guinea pig cage, Epsom salts, a sterile first aid kit and hand sanitizer when she makes time — roughly once every three weeks — to help pigeons suffering from stringfoot.

Stringfoot is when birds get string, human hair or wire wrapped around their feet, cutting off circulation. It can cause a toe or entire foot to fall off.

Griffin first noticed birds with abrasions and open sores on their feet about four years ago when she started feeding them seeds regularly. Realizing she had a first aid kit in her bag, she knew she could help. Since then, Griffin estimates she’s helped more than 100 pigeons and has upped her system of care.

Now, depending on how much time she has, Griffin will fill the bottom of the cage with a little bit of water and Epsom salt to let the bird soak. Using food to entice the bird, she’ll catch it and slip a sock with the toes cut off over the bird to stop it from flapping its wings and stressing out. Griffin will then take the bird onto her lap, gently using small scissors to cut away the string, twine or hair and then using tweezers, she’ll remove any of the remaining debris.

“Sometimes I wear gloves for this, but for the most part I would just be sanitizing my hands often and not touching my face,” she says, adding that the gloves can get in the way sometimes and make it hard to grip.

Andrea Wallace from The BCSPCA Wild Animal Rehabilitation Centre (Wild ARC) says they don’t recommend touching or feeding any wild animals.

“We want to keep them wild,” she says, adding that if you see a bird with stringfoot to bring it to Wild ARC so they can treat it, although she would not say how the staff would help the animal. “That’s not how we would do it, and I won’t describe how we would do it because we don’t want anyone to do that,” she says.

For Griffin, it’s a sense of responsibility that keeps her going out.

“I just think it’s kind of sad, so many people think pigeons are gross and hate them,” says Griffin. “This is why they live near — they trust us and see [the city] as home.”

Griffin says the pigeons can even recognize her.

“It’s not like they say ‘hey it’s you’ or anything, but eventually they know what you’re up to after a while,” she says.

Eventually, she’d like to pursue a career in wildlife rehabilitation to put her experience to use.

Reporter can’t keep a straight face talking about pigeon arrested in India for spying

Breakfast reporter Wilson Longhurst tried his best to report the unusual story of a pigeon arrested in India on suspicion of spying, but he couldn’t quite hold it together today.

The Times of India reports the bird was captured around the time of the Eid festival by villagers along the border of Pakistan and India in Jammu and Kashmir.

They handed the bird, which had been painted pink and carried a numbered band around its leg, to police, on suspicion of spying.

Police were concerned that the numbers could be a “coded message”, officials told the Times of India, and an investigation was launched.

As Longhurst reported the story on Breakfast, he did his best to remain solemn, but lost it as he reported that the owner of the pigeon in neighbouring Pakistan has appealed for the bird’s release, saying the number on it’s leg is simply his phone number.

The villager told Pakistan’s Dawn newspaper that he owns more than a dozen pigeons, that they are a “symbol of peace” and that India should “refrain from victimising innocent birds”.

And it’s not the first time – Indian authorities caught a bird in 2015 that was found to have a message written on its wings in Urdu, and in 2016 a bird was found carrying a note allegedly threatening Indian Prime Minister Narendra Modi.
