Who knows? 10 wonderful facts about owls

Page 1, ***2: Page 1 Page 2 Introduction (Mark Kulander/AFP/Getty) Owls have been using the word *** iths (including late-night comedian Stephen colbert) to bypass the trademark word "Super Bowl". Owls are loved by many people. Now the Harry Potter series has become popular, perhaps too much, because it is a flying postman in the wizarding world. (The picture above shows the Eurasian Eagle.

Owls can swim (Steve Spitzer | YouTube) Big-horned owls can swim and crawl with their powerful wings.

Is for owl "If you chase something in the water and accidentally get wet, sometimes it will be easier to swim to the shore.". Julia Ponder, executive director of the Raptor Center of the University of Minnesota, told the reporter of Life Science earlier: "When a bird flies to the shore, it usually shakes its feathers dry. This is exactly what happened in Lake Michigan in 20 14. A birdman and photographer named Steve Spitzer saw two peregrine falcons chasing a big-horned owl into the water.

Not all owls are night owls, but not all owls are night owls.

Some owls are active during the day, which means they hunt during the day. They include Strix nebulosa (pictured), Surnia ulula and Glaucidium gnoma, and Marc Devkaitis, a public information expert at Cornell Bird Laboratory in Ithaca, new york.

Probably daytime hunters, because their favorite prey, such as songbirds or small mammals, is also daytime. In addition, owls and eagles are close relatives, and eagles are daytime birds. But it is not clear whether the ancestors of owls and eagles moved during the day like eagles or at night like most owls, de Watkiss said.

Owls have impressive necks (Susan Kokin/Miami Herald /MCT/ Getty). Owls have 14 cervical vertebrae, twice as many as humans. This unique anatomical structure helps an owl (such as the striped owl in the picture) turn its head 270 degrees.

Owls can accomplish this feat because they have holes in their vertebrae, which are about 10 times the size of the blood-carrying arteries of animals. According to the previous report in Life Science, because the owl has such a large swing space, when the owl turns its head, the artery easily passes through the vertebral foramen.

This ability is the key to the survival of owls: owls don't move their eyes easily, so they need to turn their necks and look around.

The largest owl is extinct (D.Finnin/AMNH reserves all rights). The largest owl ever recorded is the giant owl (Ornimegalonyx) extinct in Cuba, and the American Museum of Natural History made a model exhibition in Cuba.

Experts are not sure whether this 3.6-foot-tall (1. 1 m) owl can fly, but its powerful long legs show that it is a gold medal runner. If it can fly or glide, it will be one of the largest birds known in the world.

Researchers found (Ornimegalonyx) remains in caves in Cuba, usually surrounded by the remains of bird prey, including sloths and now extinct rodent Judiaz.

Owls bring peace to the Middle East, or at least they let scientists and farmers from both sides communicate and cooperate with each other.

These birds of prey catch mice and voles, prompting farmers in Israel, Jordan and Palestine to build owl nests.

KD "SPS" owls can eat 6,000 rodents a year, which means farmers don't need to use toxic pesticides as much as possible to protect their crops, "Live Science reported earlier. Cooperation is still expanding, and a pilot project between Israel and Cyprus has begun. Some owls have false eyes (Michael Durham/Minden Pictures/Newsletter). The northern dwarf owl has bright yellow eyes on its face ... and black feathers on the back of its head. It looks terrible. Observe the eyes.

These "eye spots" may "slow down or prevent predators from attacking them from behind," mcgowan told Life Science. Predators don't like to attack their prey while staring at them. Eye spots will slow them down. Therefore, no matter how close they are to this little owl, predators will stare at its eyes.

Owls are not waterproof, and they are rarely seen hunting in the rain.

They gave up the oil found in many feathers, which can protect other birds from the rain. "Silent feathers are more valuable for secret hunting," Leigh Salvis wrote in the Sasquatch Series (20 16).

Simply put, "Owls' hairy body feathers absorb a lot of water," mcgowan told Field Science.

Owls recycle nests. Owls were moors when they built their nests. Salwitz wrote: "Some Bubo virginianus even live in holes made by gold-plated owls and gold-plated woodpeckers in giant cacti. Instead of building their own nests, they use nests or tree holes left by other birds, such as the long-haired woodpecker or the northern flash. "

Similarly, except for a subspecies found in Florida, the cave owl (Athene cuniculaia) does not dig its own hole, Salvis wrote. She pointed out that in the western United States, these long-legged owls live in abandoned woodchucks or badger holes.

Owls have opposite toes (all photos Canada/Alami) Owls have cheekbone toes, which means they have two "opposite thumbs", almost the same.

The owl has two claws pointing forward and will come back at two o'clock. "Movable toes actually extend more sideways than forward or backward," mcgowan told Life Science. It forms a complete claw circle when catching prey.

Snow owl flies far away. Bubo scandiacus usually lives in the Arctic, but it often does. These magnificent birds fly south, which is a journey called "breakthrough".

It is one of the biggest breakthroughs in the last century, which happened in the winter of 20 13-20 14. According to the "Blizzard Plan" to track snow owls, the southernmost areas of snow owls are Florida and Bermuda. Salwitz wrote that an owl tracked by the project was named Baltimore, and it was the star of a video on YouTube.

Another snowy owl even flew nearly 3,000 miles (4,800 kilometers) to Hawaii and landed at Honolulu International Airport 20 1 1 on Thanksgiving Day. But federal officials were worried that the owl would collide with the plane, so they killed it.

"This is the first time in the history of Hawaii. They shot! " Denver Holt, director of the Sharo Owl Institute in Montana, told * * *.
