There is evidence to suggest that crows may be among the most intelligent animals on Earth.
They can count to five. Use tools, such as sticks, to pick out insects from rotten tree stumps.
What type of brain is typical for birds
The telencephalon of birds, like the brain of mammals, is of the inverted type and consists of two large hemispheres (hemispheria cerebri), separated by a deep longitudinal fissure.
In birds, the surface of the hemispheres is usually smooth and does not have the convolutions characteristic of the brain of most mammals.
Which bird is the fastest in the world
The peregrine falcon is the fastest bird on the planet: in flight it reaches speeds of over 300 km/h.
At one time, this feathered predator was on the verge of complete extinction.
In addition, the woodcock, the slowest bird in the world, flies at a speed of 8 km/h.
What birds can do
A male kea named Bruce, who lost the upper half of his beak as a teenager and now lives in captivity, has learned to clean his feathers using small pebbles.
The parrot places such a pebble in the mandible, presses the feather between it and the tongue, and then cleans and straightens the surface of the feather.
Previously we talked about the emotionality of animals.
