What Is a Bird?
Birds are warm-blooded creatures, like mammals, but they lay eggs, like most reptiles. All birds have feathers and wings, and most birds are able to fly. Birds are amazingly varied in their shapes, sizes, colors, and behavior patterns. There are more than 9,000 different species of birds in the world.
