Birds belong to the group of vertebrates and are species that have wings that mostly allow them to fly, although there are also flightless birds.
In general, birds fly, jump, walk or swim with incredible speed and agility. Equally improbable is what happens during the breeding season. For centuries, the courtship of these species has amazed humans.
The size of the birds varies from one species to another: from 6.4 cm in the small hummingbird to about 2.74 meters in the ostrich, the largest bird in the world.
Birds have a horny beak and no teeth. They are warm-blooded, can walk, jump, and stand only on their hind legs.
Their forelimbs are shaped like wings, which allows them to fly in most birds.
Flight is the primary means of transportation for most birds, and they also use it to breed, feed, and escape from predators.
However, about 60 species of birds are flightless, they are often found on isolated islands, probably due to a lack of resources and a lack of terrestrial predators.
Communication between birds is versatile and can include sensory cues, calls, and songs. Some make a 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 depending on the species.
Birds inhabit all areas of land and all the world's oceans. They even drive them in Antarctica.
Birds usually migrate to take advantage of seasonal temperature changes around the world. Migrations vary greatly by gender.
There are more than 9,000 different species and species of birds on the planet.
