Have you ever seen a robin(知更鸟)? Robins have dark heads and red chests.
A good place to see robins is in your own backyard. Robins don't mind being around people. You may also see robins on lawns(草坪) or in parks. They are looking for worms and bugs to eat.
Early in spring, robins build their nests(巢). They build them in trees. Robins hide the nests in trees so that they will be safe.
The nests are made of grass, sticks, and mud. The mud makes everything together. The mother robin lays(产蛋) one egg a day for three or four days. She sits on them to keep them warm. The eggs are blue. After the babies come out, both the mother and father feed the babies. The young birds have spots on their chests.
