Перевод текста do you know that birds are found in almost every part of the globe. such as ostriches and penguins, cannot fly. instead, the ostrich can run very fast and the penguin uses its wings as flippers for swimming. all birds lay eggs with hard, waterproof shells. birds are the only animals that have feathers. a very small bird, such as a hummingbird, may have about 900 feathers, while a large bird likea swan may have over 25 000. birds have excellent eyesight, often better than human sight. they have an extra eyelid to protect their eyes from dust and rain while flying. most birds have a poor sense of smell, but excellent hearing. some birds spend summer in one part of the world and winter in another to take advantage of seasonal food suplies. swallows, for example, rear their families in northern europe and north america in summer , when insects are plentiful, but fly south in autumn as the insects disappear. such journeys are called migration. заранее !
