Do you see a robin (知更鸟)? Robins are common birds that live in Asia, Europe and Africa. They are small, about 14 centimeters long, with the weight of about 20 grams. They have dark heads and red chests.

A good place to see robins is your own backyard. Robins don’t seem to mind being around people. You may also see robins on lawns (草坪) in parks. They like eating worms and bugs best.

Early in spring, robins build their nests in trees. Some robins can live up to 12 years. These birds may build 20 or even 30 nests in their lifetime! The nests are made of grass, sticks and mud. The mud puts everything together.

The mother robin lays one egg for three or four days. She sits on them to keep them warm. The eggs are blue. After the babies hatch (孵化), both the mother and the father feed them.

Most robins stay at one place through the four seasons. But some of them will fly to southern countries in winter.
