They peck at the pavement; they coo overhead; they swoop in hundreds across town squares: Pigeons have become such a permanent fixture in our urban landscapes that cities would seem oddly vacant without them.
But while many people harbor resentment for these ubiquitous creatures — labeling them “rats with wings” — few of us stop to ponder how pigeons became so numerous in the first place, and what our own role in their urban colonization might be.
Today, in fact, there are more than 400 million pigeons worldwide, most of which live in cities. But that wasn’t always the case. The city pigeons we know today are actually descended from a wild creature known as the rock dove (Columba livia): As its name suggests, this bird prefers a rocky coastal cliff habitat to the conveniences of city life. [Why Are Chickens So Bad at Flying?]
But going as far back as 10,000 years ago, written and fossil records show that people living in ancient Mesopotamia (modern-day Iraq) and Egypt began coaxing these doves with food into human-inhabited areas, encouraging them to roost and breed on their land. “Back then, we brought rock doves into cities to eat as livestock,” Steve Portugal, a comparative ecophysiologist who studies bird flight and behavior, told Live Science. The plump, young birds especially — known as “squabs” — became a prized source of protein and fat. People then began domesticating and breeding the birds for food, creating subspecies that led to the diversity of urban pigeons known today.
Along the way, humans began to realize that pigeons were useful for much more than their meat. As the birds grew more popular in the Middle East, North Africa and Western Europe in the ensuing centuries, people began to tap into their innate talent for navigation — the same skill that makes homing pigeons famous today. Ancient records show that Mediterranean sailors used the birds to point floundering ships toward land. In cities, they became increasingly valuable as airborne messengers that could deliver important information across large distances.
From there, humanity’s appreciation for the animals only grew: Although pigeons were initially domesticated as a food source, “as other poultry became more popular, pigeons fell out of favor for eating and people began breeding them as a hobby,” said Elizabeth Carlen, a doctoral student at Fordham University in New York City who studies the evolution of urban pigeons.
By the 1600s, rock doves — non-native to the United States — had reached North America, transported by ships in the thousands. Rather than being a food source, it’s most likely that the birds were brought across from Europe to satiate the growing pigeon-breeding trend among hobbyists, said Michael Habib, a paleontologist in the Dinosaur Institute at the Los Angeles County Museum of Natural History, and the University of Southern California.
Inevitably, birds escaped captivity, and began to breed freely in American cities. “We created this novel [urban] habitat and then we basically engineered an animal that does very well in that novel habitat,” Habib told Live Science. “They were successful in cities because we engineered them to be comfortable living around humans.” [Do Birds Really Abandon Their Chicks If Humans Touch Them?]
Cities became the perfect backdrop for the pioneering pigeons’ success. “Pigeons are naturally cliff-dwellers and tall buildings do a pretty great job at mimicking cliffs,” Carlen told Live Science. “Ornate facing, window sills and air-conditioning units provide fantastic perches for pigeons, similar to the crevices found on the side of a cliff.”
Another trait that makes pigeons more adaptable is their appetite. While other bird species have to rely on supplies of berries, seeds and insects, pigeons can eat just about anything that humans toss in the trash. “Other species are specialists and pigeons are the ultimate generalists,” Portugal said. “And the food is endless: I don’t think too many pigeons go to bed hungry!”
The pigeon’s unusual breeding biology seals the deal: Both parents rear their chicks on a diet of special protein- and fat-rich milk produced in a throat pouch called the crop. So, instead of having to rely on insects, worms and seeds to keep their young alive — resources that would be scarcer in cities — pigeons can provide for their offspring no matter what, Portugal says: “As long as the adults can eat, they can feed their babies, too.”
All these traits give pigeons a competitive edge compared with other species that might attempt survival in cities. Combined with the pigeon’s prolific breeding habits (parents can produce up to 10 chicks a year), it’s easy to see why these birds have become so populous around the world.
Not everyone appreciates the urban phenomenon that these birds have become — hence the “rat with wings” moniker. That’s understandable to some extent: Pigeons can spread diseases, and the mounds of guano they splatter across buildings can be cumbersome and costly to clean.
Despite this, Portugal sees a benefit to their presence in our urban environments. “They’re actually one of the few bits of wildlife that people get to interact with in cities now,” he said. What’s more, “they’re super-adaptable and super-successful; they’re the ultimate survivors. Actually, we can learn a lot from them.”

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.

Some folks consider them an endearing part of urban life, others see them as an aggravation, but everyone recognizes this familiar wild neighbor. Pigeons may have been the first bird species to be domesticated, possibly as early as 6,500 years ago. The Egyptians used pigeons to carry the news of the coronation of Ramses III — more than 3,000 years before the United States was founded. Pigeons were well-equipped for this job, as they reach flight speeds of 15 to 60 miles per hour!
The rock dove, as the species also is known, is a European immigrant. Pigeons were introduced to North America by early European settlers. You’ll find pigeons in almost any city, town, or suburb on the continent. Their diet consists primarily of grains and seeds, along with insects and some greens — but pigeons aren’t terribly picky, and they’ll happily accept human food scraps and leftovers when available. From a pigeon’s point of view, city living can’t be beat. Food and water are readily available. Predators are few and far between. Plus, there’s plenty of free housing — pigeons like to live in large groups on window ledges, rooftops, bridges, and warehouses as these offer room for whole flocks to rest or take shelter in close proximity.
Family Life
Pigeons live in groups called “flocks.” Each flock has an equal number of male and female members. A courting male pursues his intended mate on the ground, circling her, with his neck feathers inflated and his tail spread, bowing and cooing all the while. Pigeons mate for life, but if one partner dies the survivor generally will attempt to find another mate.
Pigeons show a strong affinity for human-built structures. Nests, a haphazard combination of twigs, leaves, and a few feathers, are built on window ledges, behind signs, and under bridges. Parents take turns incubating the clutch of one or two white, unmarked eggs for between 16 and 19 days. After the eggs hatch, both parents feed the baby pigeons, or squabs, a crop secretion called “pigeon milk,” which is produced from the lining of the crop, a sac-like food storage chamber located under the bird’s esophagus. The milk is a highly nutritious and an efficient way of feeding young. Squabs fledge at four to six weeks of age but remain dependent on their parents for as long as the adults will tolerate them — generally another one or two weeks. Individuals may be capable of breeding at six months of age.
Pigeons leave their nesting and roosting sites during daylight hours to search for food, but they return at night, as well as periodically during the day when raising young.
Found an injured or orphaned pigeon?
Wildlife rehabilitation centers provide care for injured and orphaned wildlife until the animal can be released back to the wild. In most states, wildlife rehabilitation can be practiced only with a state and/or federal license.
Adult pigeons may suffer from broken bones, parasite infestations, and diseases, some of which may present a human health hazard. Without proper intervention, these birds may die from their injuries or be permanently disabled. Rehabilitators receive the special training needed to assess these problems and offer appropriate aid.
Baby pigeons may be covered with sparse, fuzzy down or spiky, emerging feathers, and their beaks can look rather deformed. Like all other infants, squabs have unique nutritional requirements. Baby bird food available at pet stores may claim to be appropriate for all birds, but this is simply not true. Furthermore, squabs must be fed through a tube inserted into their crop several times a day – a risky procedure even for experienced wildlife rehabilitators. Problems that result from an inappropriate diet, such as metabolic bone disease (also known as rickets), can debilitate an animal for life.
If you’ve found a pigeon in need of assistance, contact a wildlife rehabilitator.

POSSIBLE CONFLICTS & SOLUTIONS
At first glance, the arrangement we have with pigeons appears to be ideal; we provide room and board and in return the birds add a little warmth and color to our cold concrete canyons. So what’s the problem? In a word — droppings.
Not only is pigeon poop unsightly, it can damage buildings, monuments, and automobiles, and if allowed to accumulate, human health problems may arise. A little patience and understanding go a long way toward resolving these problems. Removing the animals in question may seem like an obvious answer. The truth, however, is that results with this approach are short-lived because removal simply creates a vacancy that other animals quickly fill. Humane conflict prevention and resolution is less expensive and more effective in the long run. People can live in harmony with wildlife – you just have to know your wild neighbors!
Roost inhibitors, distress call devices, predator-shaped kites and scarecrows, and netting are effective and humane ways to prevent and/or solve most conflicts with pigeons. Go to our humane exclusion resources page to find vendors that sell these devices.
PUBLIC HEALTH CONCERNS
Pigeons are known carriers of cryptococcus and salmonella. However, there is little evidence linking pigeons directly to infections in humans.
Information about humane prevention of pigeon conflicts was prepared by Kieran Lindsey, Natural Assets Consulting, and reviewed by Richard F. Johnston, Ph.D., Professor Emeritus, Natural History Museum, University of Kansas.

When it comes to birds, there may be more than just avian flu to be worried about. It has been suggested that there are over 60 other diseases that birds and their droppings can carry. The problem is especially worrisome in residential areas, as many of them are airborne and can be transferred to humans just by being around droppings.

Chicken farms can be fairly easily secured. With a combination of visual scare devices, sonic distress call emitters, ultrasonic disrupters and roost inhibitors other birds shouldn’t be a problem. If farmers just took this preventative action it could help contain the bird flu outbreak a good deal.
- Histoplasmosis is a respiratory disease that may be fatal. It results from a fungus growing in dried bird droppings.
- Candidiasis is a yeast or fungus infection spread by pigeons. The disease affects the skin, the mouth, the respiratory system, the intestines and the urogenital tract, especially the vagina. It is a growing problem for women, causing itching, pain and discharge.
- Cryptococcosis is caused by yeast found in the intestinal tract of pigeons and starlings. The illness often begins as a pulmonary disease and may later affect the central nervous system. Since attics, cupolas, ledges, schools, offices, warehouses, mills, barns, park buildings, signs, etc. are typical roosting and nesting sites, the fungus is apt to found in these areas.
- St. Louis Encephalitis, an inflammation of the nervous system, usually causes drowsiness, headache and fever. It may even result in paralysis, coma or death. St. Louis encephalitis occurs in all age groups, but is especially fatal to persons over age 60. The disease is spread by mosquitoes which have fed on infected house sparrow, pigeons and house finches carrying the Group B virus responsible for St. Louis encephalitis.
- Salmonellosis often occurs as “food poisoning” and can be traced to pigeons, starlings and sparrows. The disease bacteria are found in bird droppings; dust from droppings can be sucked through ventilators and air conditioners, contaminating food and cooking surfaces in restaurants, homes and food processing plants.
- E.coli. Cattle carry E. coli 0157:H7. When birds peck on cow manure, the E. coli go right through the birds and the bird droppings can land on or in a food or water supply.
Besides being direct carriers of disease, nuisance birds are frequently associated with over 50 kinds of ectoparasites, which can work their way throughout structures to infest and bite humans. About two-thirds of these pests may be detrimental to the general health and well-being of humans and domestic animals. The rest are considered nuisance or incidental pests.
A few examples of ectoparasites include:
- Bed bugs (Cimex lectularius) may consume up to five times their own weight in blood drawn from hosts which include humans and some domestic animals. In any extreme condition, victims may become weak and anemic. Pigeons, starlings and house sparrows are known to carry bed bugs.
- Chicken mites (Dermanyssus gallinae) are known carriers of encephalitis and may also cause fowl mite dermatitis and acariasis. While they subsist on blood drawn from a variety of birds, they may also attack humans. They have been found on pigeons, starlings and house sparrows.
- Yellow mealworms (Tenebrio molitor), perhaps the most common beetle parasites of people in the United States, live in pigeon nests. It is found in grain or grain products, often winding up in breakfast cereals, and may cause intestinal canthariasis and hymenolespiasis.
- West Nile Virus while West Nile is technically not transmitted to humans from birds, humans can get infected by the bite of a mosquito who has bitten an infected bird. The obvious lesson is that the fewer birds there are in any given area, the better. This translates into a smaller chance of an infected bird in that area, a smaller chance of a mosquito biting an infected bird and then biting a human.

Though they’re often described as “rats with wings” (a phrase popularized by the movie Stardust Memories), pigeons are actually pretty cool. From homing instincts to misleading rump feathers, here are 15 things you might not know about these avian adventurers.
1. THEY MIGHT BE THE FIRST DOMESTICATED BIRD.
The common city pigeon (Columba livia), also known as the rock pigeon, might be the first bird humankind ever domesticated. You can see them in art dating back as far as 4500 BCE in modern Iraq, and they’ve been a valuable source of food for thousands of years.
2. THEY WON OVER CHARLES DARWIN—AND NIKOLA TESLA.
Pigeon-breeding was a common hobby in Victorian England for everyone from well-off businessmen to average Joes, leading to some fantastically weird birds. Few hobbyists had more enthusiasm for the breeding process than Charles Darwin, who owned a diverse flock, joined London pigeon clubs, and hobnobbed with famous breeders. Darwin’s passion for the birds influenced his 1868 book The Variation of Animals and Plants Under Domestication, which has not one but two chapters about pigeons (dogs and cats share a single chapter).
Nikola Tesla was another great mind who enjoyed pigeons. He used to care for injured wild pigeons in his New York City hotel room. Hands down, Tesla’s favorite was a white female—about whom he once said, “I loved that pigeon, I loved her as a man loves a woman and she loved me. When she was ill, I knew and understood; she came to my room and I stayed beside her for days. I nursed her back to health. That pigeon was the joy of my life. If she needed me, nothing else mattered. As long as I had her, there was a purpose in my life.” Reportedly, he was inconsolable after she died.
3. THEY UNDERSTAND SPACE AND TIME.
In a 2017 Current Biology study, researchers showed captive pigeons a series of digital lines on a computer screen for either two or eight seconds. Some lines were short, measuring about 2.3 inches across; others were four times longer. The pigeons were trained to evaluate either the length of the line or how long it was displayed. They found that the more time a line was displayed, the longer in length the pigeon judged it to be. The reverse was true too: If the pigeons encountered a longer line, they thought it existed in time for a greater duration. Pigeons, the scientists concluded, understand the concepts of both time and space; the researchers noted “similar results have been found with humans and other primates.”
It’s thought that humans process those concepts with a brain region called the parietal cortex; pigeon brains lack that cortex, so they must have a different way of judging space and time.
4. THEY CAN FIND THEIR WAY BACK TO THE NEST FROM 1300 MILES AWAY.
The birds can do this even if they’ve been transported in isolation—with no visual, olfactory, or magnetic clues—while scientists rotate their cages so they don’t know what direction they’re traveling in. How they do this is a mystery, but people have been exploiting the pigeon’s navigational skills since at least 3000 BCE, when ancient peoples would set caged pigeons free and follow them to nearby land.
Their navigational skills also make pigeons great long-distance messengers. Sports fans in ancient Greece are said to have used trained pigeons to carry the results of the Ancient Olympics. Further east, Genghis Khan stayed in touch with his allies and enemies alike through a pigeon-based postal network.
5. THEY SAVED THOUSANDS OF HUMAN LIVES DURING WORLD WARS I AND II.
Pigeons’ homing talents continued to shape history during the 20th century. In both World Wars, rival nations had huge flocks of pigeon messengers. (America alone had 200,000 at its disposal in WWII.) By delivering critical updates, the avians saved thousands of human lives. One racing bird named Cher Ami completed a mission that led to the rescue of 194 stranded U.S. soldiers on October 4, 1918.
6. TWO PIGEONS ALMOST DISTRACTED FROM THE DISCOVERY OF EVIDENCE OF THE BIG BANG.
In 1964, scientists in Holmdel, New Jersey, heard hissing noises from their antenna that would later prove to be signals from the Big Bang. But when they first heard the sound, they thought it might be, among other things, the poop of two pigeons that were living in the antenna. “We took the pigeons, put them in a box, and mailed them as far away as we could in the company mail to a guy who fancied pigeons,” one of the scientists later recalled. “He looked at them and said these are junk pigeons and let them go and before long they were right back.” But the scientists were able to clean out the antenna and determine that they had not been the cause of the noise. The trap used to catch the birds (before they had to later be, uh, permanently removed) is on view at the Smithsonian Air & Space Museum.
7. YOU CAN TRAIN THEM TO BE ART SNOBS …
Japanese psychologist Shigeru Watanabe and two colleagues earned an Ig Nobel Prize in 1995 for training pigeons, in a lab setting, to recognize the paintings of Claude Monet and Pablo Picasso and to distinguish between the painters. The pigeons were even able to use their knowledge of impressionism and cubism to identify paintings of other artists in those movements. Later, Watanabe taught other pigeons to distinguish watercolor images from pastels. And in a 2009 experiment, captive pigeons he’d borrowed were shown almost two dozen paintings made by students at a Tokyo elementary school, and were taught which ones were considered “good” and which ones were considered “bad.” He then presented them with 10 new paintings and the avian critics managed to correctly guess which ones had earned bad grades from the school’s teacher and a panel of adults. Watanabe’s findings indicate that wild pigeons naturally categorize things on the basis of color, texture, and general appearance.
8. … AND TO DISTINGUISH WRITTEN WORDS.
In a 2016 study, scientists showed that pigeons can differentiate between strings of letters and actual words. Four of the birds built up a vocabulary of between 26 and 58 written English words, and though the birds couldn’t actually read them, they could identify visual patterns and therefore tell them apart. The birds could even identify words they hadn’t seen before.
9. FLUFFY PIGEON FEET MIGHT ACTUALLY BE PARTIAL WINGS.
A few pigeon breeds have fuzzy legs—which hobbyists call “muffs”—rather than scaly ones. According to a 2016 study, the DNA of these fluffy-footed pigeons leads their hind legs to take on some forelimb characteristics, making muffed pigeon legs look distinctly wing-like; they’re also big-boned. Not only do they have feathers, but the hindlimbs are somewhat big-boned, too. According to biologist Mike Shapiro, who led the study, “pigeons’ fancy feathered feet are partially wings.”
10. SOME PIGEONS DISTRACT FALCONS WITH WHITE RUMP FEATHERS.
In a life-or-death situation, a pigeon’s survival could depend upon its color pattern: Research has shown that wild falcons rarely go after pigeons that have a white patch of feathers just above the tail, and when the predators do target these birds, the attacks are rarely successful.
To figure out why this is, Ph.D. student Alberto Palleroni and a team tagged 5235 pigeons in the vicinity of Davis, California. Then, they monitored 1485 falcon-on-pigeon attacks over a seven-year span. The researchers found that although white-rumped pigeons comprised 20 to 25 percent of the area’s pigeon population, they represented less than 2 percent of all the observed pigeons that were killed by falcons; the vast majority of the victims had blue rumps. Palleroni and his team rounded up 756 white- and blue-rumped pigeons and swapped their rump feathers by clipping and pasting white feathers on blue rumps, and vice versa. The falcons had a much easier time spotting and catching the newly blue-rumped pigeons, while the pigeons that received the white feathers saw predation rates plummet.
Close observation revealed that the white patches distract birds of prey. In the wild, falcons dive-bomb other winged animals from above at high speeds. Some pigeons respond by rolling away in midair, and on a spiraling bird, white rump feathers can be eye-catching, which means that a patch of them may divert a hungry raptor’s focus long enough to make the carnivore miscalculate and zip right past its intended victim.
11. DODOS WERE RELATED TO TODAY’S PIGEONS.
Though most of this list focuses on the rock pigeon, there are 308 living species of pigeons and doves. Together, they make up an order of birds known as the columbiformes. The extinct dodo belonged to this group as well.
Flightless and (somewhat) docile, dodos once inhabited Mauritius, an island near Madagascar. The species had no natural predators, but when human sailors arrived with rats, dogs, cats, and pigs, it began to die out, and before the 17th century came to a close, the dodo had vanished altogether. DNA testing has confirmed that pigeons are closely related to the dodo, and the vibrant Nicobar pigeon (above) is its nearest genetic relative. A multi-colored bird with iridescent feathers, this near-threatened creature is found on small islands in the South Pacific and off Asia. Unlike the dodo, it can fly.
12. AT ONE POINT, MORE THAN ONE-QUARTER OF ALL THE BIRDS LIVING IN THE U.S. MAY HAVE BEEN PASSENGER PIGEONS.
Wild/feral rock pigeons reside in all 50 states, which makes it easy to forget that they’re invasive birds. Originally native to Eurasia and northern Africa, the species was (most likely) introduced to North America by French settlers in 1606. At the time, a different kind of columbiform—this one indigenous—was already thriving there: the passenger pigeon (Ectopistes migratorius). As many as 5 billion of them were living in America when England, Spain, and France first started colonizing, and they may have once represented anywhere from 25 to 40 percent of the total U.S. bird population. But by the early 20th century, they had become a rare sight, thanks to overhunting, habitat loss, and a possible genetic diversity issue. The last known passenger pigeon—a captive female named Martha—died on September 1, 1914.
13. THEY’RE REALLY GOOD AT MULTITASKING.
According to one study, they’re more efficient multitaskers than people are. Scientists at Ruhr-Universitat Bochum put together a test group of 15 humans and 12 pigeons and trained all of them to complete two simple jobs (like pressing a keyboard once a light bulb came on). They were also put in situations wherein they’d need to stop working on one job and switch over to another. In some trials, the participants had to make the change immediately. During these test runs, humans and pigeons switched between jobs at the same speed.
But in other trials, the test subjects were allowed to complete one assignment and then had to wait 300 milliseconds before moving on to the next job. Interestingly, in these runs, the pigeons were quicker to get started on that second task after the period ended. In the avian brain, nerve cells are more densely packed, which might enable our feathered friends to process information faster than we can under the right circumstances.
14. PIGEONS PRODUCE FAKE “MILK.”
Only mammals produce genuine milk, but pigeons and doves (along with some other species of birds) feed their young with something similar—a whitish liquid filled with nutrients, fats, antioxidants, and healthy proteins called “crop milk.” Both male and female pigeons create the milk in the crop, a section of the esophagus designed to store food temporarily. As is the case with mammal milk, the creation of crop milk is regulated by the hormone prolactin. Newly-hatched pigeons drink crop milk until they’re weaned off it after four weeks or so. (And if you’ve ever asked yourself, “Where are all the baby pigeons?” we have the answer for you right here.)
15. ONE STUDY SUGGESTS THAT, GIVEN THE RIGHT CONDITIONS, THEY’RE AS GOOD AT IDENTIFYING CANCER AS DOCTORS.
We’ve already established that pigeons are excellent at differentiating between artists and words, but a 2015 study revealed they can also distinguish between malignant and benign growths in the right conditions. Researchers at University of California Davis Medical Center put 16 pigeons in a room with magnified biopsies of potential breast cancers. If the pigeons correctly identified them as either benign or malignant, they got a treat, According to Scientific American.
“Once trained, the pigeons’ average diagnostic accuracy reached an impressive 85 percent. But when a “flock sourcing” approach was taken, in which the most common answer among all subjects was used, group accuracy climbed to a staggering 99 percent, or what would be expected from a pathologist. The pigeons were also able to apply their knowledge to novel images, showing the findings weren’t simply a result of rote memorization.”
Mammograms proved to be more of a challenge, however; the birds could memorize signs of cancer in the images they were trained on but could not identify the signs in new images.
No matter how impressive their results, “I don’t anticipate that pigeons, no matter how good they become at pathology or radiology, will be playing a role in actual patient care—certainly for the foreseeable future,” study co-author Richard M. Levenson told Scientific American. “There are just too many regulatory barriers—at least in the West.”

Earth’s magnetic field plays a vital role in everything from animal migration to protecting the Earth from the Sun’s harsh solar wind. Now, a recent study finally sheds light on how some birds visually see Earth’s magnetic field. Birds use Earth’s magnetic field as sort of a heads-up display to help them navigate the globe.
The Earth’s magnetic field is a result of the movement or convection of liquid iron in the outer core. As the liquid metal in the outer core moves, it generates electric currents, which lead to a magnetic field. The continual movement of liquid metal through this magnetic field creates stronger electrical currents and thus a stronger magnetic field. This positive feedback loop is called the geomagnetic dynamo.
While scientists have known for quite some time that birds can see Earth’s magnetic field, it was unclear exactly how birds are able to visualize the magnetic field. Two recent studies from researchers at Lund University in Sweden and Carl von Ossietzky University Oldenburg in Germany discovered that the ability is a result of a special protein in bird’s eyes. The two papers studied European robins and zebra finches and found evidence for an unusual eye protein called Cry4.
The Cry4 protein is part of a class of protein called a cryptochrome that is sensitive to blue light. Cryptochromes are found in both plants and animals and are responsible for circadian rhythms in various species. In the two bird species above, it appears that the presence of cryptochromes, specifically the Cry4 protein, is responsible for the ability of birds to visually detect Earth’s magnetic field.
The ability to see Earth’s magnetic field, known as magnetoreception, relies on the presence of specifically the blue wavelength of light. The complex process involves “radical” intermediate molecules which are sensitive to Earth’s magnetic field. The Earth’s magnetic field, as it relates to the direction the bird is facing, could alter the intermediate radical molecules differently, giving the bird a sense for where it is facing in relation to the Earth’s magnetic field.
The research team also found that the Cry4 protein was produced in much higher amounts in European robins during migration season. Perhaps this would give the robin a more precise picture of Earth’s magnetic field throughout its migration.
While the exact way birds visualize Earth’s magnetic field is part of further investigation, scientists believe the Cry4 protein acts as sort of a filter over the bird’s vision. This filter would allow birds to see a sort of compass of the Earth and direct their migratory flights accordingly.
Scientists at the University of Illinois at Urbana-Champaign believe birds see Earth’s magnetic field through a filter similar to the figure above. This would act to guide birds in the right direction through migration.
