very beautiful amazing birds #1

Birds belong to the group of vertebrates and are a species that mostly have wings that allow them to fly, although there are some non-flying birds as well.
In general, birds fly, jump, walk or swim with incredible speed and lightness. What happens in the breeding season is also incredible. For centuries, the courtship of this species has fascinated man.

The size of birds varies from one species to another, they can measure from 6.4 cm in the case of a small hummingbird, to about 2.74 meters in an ostrich, the largest bird in the world.
Birds have horny beaks and no teeth. They are warm-blooded, can walk, jump and stand only on the hind limbs.
Their forelimbs are reshaped with wings, allowing them, in most birds, to fly.
Flying is the main means of movement for most birds, and they also use it to breed, feed themselves, and escape their predators.
However, about 60 species of birds do not fly, and are often found on isolated islands, possibly due to the scarcity of resources and the absence of predators on land.
Communication between birds is versatile and can include sensory signals, calls, and songs. Some make a large variety of sounds and calls.
The diet of birds includes a large amount of food such as nectar, fruits, plants, seeds, carrion and various small animals including other birds. However, the diet varies by species.
Birds live in all land areas and in all oceans of the world. They are found even in the Antarctic region.
Birds generally migrate to take advantage of seasonal temperature differences around the world. Migrations vary greatly by gender.
There are more than 9,000 different species or species of birds on this planet.
