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.

Scientists have discovered the secret of pigeons’ remarkable ability to navigate perfectly over journeys of several hundred miles. They do it by smell.
Research found that pigeons create ‘odour’ maps of their neighbourhoods and use these to orient themselves. This replaces the idea that they exploited subtle variations in the Earth’s magnetic field to navigate.
‘This is important because it is the first time that magnetic sensing and smell have been tested side by side,’ said Anna Gagliardo, of the University of Pisa, who led the research.
The discovery that birds have an olfactory positioning system is the latest surprising discovery about bird migration. Birds know exactly when to binge on berries or insects to fatten themselves for long flights, and some species recognise constellations, which helps them to fly at night. Birds also travel immense distances: the average Manx shearwater travels five million miles during its life.
Research into navigation has included an experiment in which robins were released with a patch over one eye – some on the right eye, some on the left. The left-eye-patched robins navigated well, but those with right-eye patches got hopelessly lost. ‘It is a very strange finding,’ said Graham Appleton, of the British Trust for Ornithology . ‘It is clear the cues robins use to navigate are only detectable in one eye. Why that should be the case, I have no idea.’
In the Pisa experiments, Gagliardo, working with Martin Wild of the University of Auckland , followed up experiments done in 2004, which showed that pigeons could detect magnetic fields. She argued that this did not mean they actually did.
So in 24 young homing pigeons she cut the nerves that carried olfactory signals to their brains. In another 24 pigeons she cut the trigeminal nerve, which is linked to the part of the brain involved in detecting magnetic fields.
The 48 birds were released 30 miles from their loft. All but one of those deprived of their ability to detect magnetic fields were home within 24 hours, indicating that it was not an ability that helped them to navigate. But those who had been deprived of their sense of smell fluttered all over the skies of northern Italy. Only four made it home.
Gagliardo and her team conclude that pigeons read the landscape as a patchwork of odours.
Every spring, hundreds of millions of birds head north in order to exploit new resources. Gulls head to the Arctic to make use of the 24 hours of daylight prevailing there, while swallows and other birds leave Africa to exploit the British summertime.
The navigation involved in these long journeys is still a cause of considerable debate among scientists. Among the main theories are suggestions that some birds remember visual maps of the terrain they fly over; that they follow the lines of Earth’s magnetic field; and that night-time flyers remember star maps of the sky.
However, the discovery of pigeons’ prowess at exploiting smells is considered important because their navigational abilities are some of the most acute in the natural world. Pigeons excel at getting home when released in unfamiliar locations. That they achieve such accuracy using smell is all the more surprising.

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.

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.

In the third floor hallway of the Pentagon, just outside the Army Chief of Staff’s office, there is a pigeon.
Walking the corridors, the lifelike pigeon stands out among the cases of military history that display Revolutionary-era bayonets, Civil War uniforms and replicas of helicopters used in Vietnam. Upon closer inspection, one might notice the pigeon is so life-like because it has been taxidermied. It’s also missing one leg.
That pigeon’s name is “President Wilson” — an unsung hero of World War I that made a daring flight to save U.S. troops exactly 100 years ago on Friday.
President Wilson was a military carrier pigeon, one of many in the U.S. Army Signal Corps that delivered messages between commanders and troops on the front lines. The pigeons were especially useful tools of communication during World War I when the telephone and telegraph were still unreliable new technologies.
According to U.S. military accounts recorded in the U.S. Army Center of Military History and the National Archives, Wilson was born in France and first assigned to the U.S. Army’s newly formed Tank Corps, delivering messages to Tank Battalions commanded by Col. George S. Patton in the Battle of Saint-Mihiel.
But soon afterward, Wilson was assigned to an infantry unit conducting operations near Grandpré during the Meuse-Argonne Offensive.
On the morning of Oct. 5, 1918, his unit came under attack, and Wilson was dispatched to send a message that the unit needed artillery support. During the 25-mile journey, German soldiers spotted him and began firing into his flight path. (It should be noted that some accounts of Wilson’s heroics place the event as occurring on Nov. 5, but multiple historians reached by ABC corroborated the Oct. 5 date.)
Wilson was hit several times, losing a leg and suffering a wound to his chest, but he managed to deliver the message in a record 25 minutes.
Surviving his wounds, Wilson was retired and sent to the U.S. Army Signal Corps Breeding and Training Center at Fort Monmouth, New Jersey, where he would live another eleven years.
After his death, Wilson was taxidermied and presented to the Smithsonian Institution before being transferred to the custody of the U.S. Army in 2008. Now, located in the prestigious halls of the U.S. military’s headquarters in Arlington, Virginia, Wilson serves as a reminder that these simple birds — often considered a nuisance by the general public — were once war heroes.
Carrier pigeons were used by both the Allied and Central Powers during World War I and could even provide updates to military commanders when launched in midair from planes.
“Launched mid-mission, the birds would fly back to their coops and update ground commanders on what the pilots had observed,” the National Archives wrote in a blog post in January. “Quick updates like this were essential for leaders to know what the battlefield looked like and what the enemy was doing in its own trenches.”
“Tanks carried the birds in order to relay the advance of individual units. Even after the introduction of the radio, pigeons were often the easiest way to help coordinate tank units without exposing the men to dangerous fire. Without a radio set, the soldiers would have had to leave the relative safety of their tanks to relay or receive orders,” the Archives said.
When the pigeons weren’t in use, they were stored in mobile units, often converted horse carriages or even double-decker buses.
The birds are thought to use low-frequency sound waves to map their environments and find their way from location to location.
Another famous World War I pigeon was known as Cher Ami — his moment of heroism came during the Meuse-Argonne Offensive in the fall of 1918.
The German Army surrounded elements of the 77th Division for five days, at one moment confusing the Americans as they accidentally shelled their own men in an attempt to fire at the enemy.
Messages were unable to get to U.S. commanders, so Cher Ami was released as the division’s last hope. Like Wilson, Cher Ami flew through a barrage of gunfire, also sustaining injuries to his leg and chest. But he successfully delivered the message, ending the friendly fire.
The French even awarded Cher Ami the Croix de Guerre with Palm, a military decoration, for his service.
Military carrier pigeons were again used in World War II. In that war, 32 pigeons were awarded the United Kingdom’s Dickin Medal for their heroic actions.
