BIRDS
Birds fly by flapping their wings.
Birds species lay their eggs in shelters called nests.
They provide a safe, warm place to keep themselves warm.
When an egg is laid, it contains just the yolk and the white part.
Birds of prey have a sharp, hooked beak.
A bird's feather contains the barps, the vane and the rachis.
The whistling swan has over 25,000 feathers.
