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.
