History of Birds
Birds are like dinosaurs in many ways: they both lay eggs in nests, and they both walk mainly on their hind legs (Birds use their front legs as wings). Many dinosaurs were warm-blooded, like birds. Some dinosaurs even had feathers, like birds. Some dinosaurs had beaks, like birds, instead of teeth.
Birds ate the same things as small meat-eating dinosaurs - worms and small insects like flies, grasshoppers, bees and mosquitoes, and meat from dead reptiles and mammals and frogs. Sea birds also ate mollusks like clams and mussels.
