Birds

Information about the Birds:

Birds – the Class of Aves – are animals who are feathered, winged, bipedal, warm-blooded and lay eggs. Based upon the fossil evidence, many scientists believe that birds are today’s descendants of the dinosaurs. There are about 10,000 species of birds known to science alive on the planet today.

The smallest is the bee hummingbird at a mere 2 inches (5 cm) and the largest is the ostrich which grows to 9 feet (2.74 m). Birds have no teeth, a four chambered heart and a very lightweight but durable skeleton, generally with hollow bones. All living species of birds have wings in some form, and only the extinct Moa did not.

They are bright animals, with parrots and corvids (crows, jays, ravens, magpies) being especially smart and excellent at problem solving. Many birds migrate hundred or thousands of miles each year, usually for warmer climates to breed. Birds are one of the few animals that are found on all seven continents on the planet.
