According to a 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. 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. Then, they monitored 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 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. Though most of this list focuses on the rock pigeon, there are 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. Originally native to Eurasia and northern Africa, the species was most likely introduced to North America by French settlers in 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.
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, 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 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. 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. 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've already established that pigeons are excellent at differentiating between artists and words, but a 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.
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. Earlier this year, the Monterey Bay Aquarium found two male baby otters—just weeks old—on the coast of California with no adult sea otters in sight. At that point, the sea otter pups will start their gradual transition from the nursery to the Regenstein Sea Otter Habitat, where visitors will have a chance to see them. This year marks the 43rd annual Oktoberfest—one of the biggest Oktoberfest celebrations outside of Germany more than , people attend the three-day event.
15 Incredible Facts About Pigeons | Mental Floss
On the afternoon of Thursday, September 19, wiener dogs and their owners and handlers gathered in downtown Cincinnati for the "Running of the Wieners. The winner of each heat advanced to the final round, where the top three finishers were decided. Leo and Bucky , two other doxies, placed second and third, respectively. Importance of pigeons has been underestimated for years, but we will explain more about these beautiful birds and introduce you to their spiritual and symbolic meaning.

They can get used to every living condition on our planet and outlive tough environments. They feed of whatever they can find. Since they live near people, they mostly get their food from us.
