The story of birds

Small, fast, free to fly in the sky, it's birds. This is a class of animals that are very diverse and rich in types and colors, each species has its own color, its own beauty.

Currently, there are about 10,000 species of birds survive, making them the most diverse class of animals. Bird layers inhabit ecosystems across the globe, from the Arctic to Antarctica. Birds vary in size, from as small as 5 cm (such as Mellisuga helenae - a hummingbird) to as large as 2.7 m (like ostriches).

Birds are animals that live in flocks, they communicate with each other through cries and songs, participate in herd activities such as cooperation in reproduction, hunting, moving and attacking against enemies.
