Thousands of species of birds live all over the world all varying in size, color and markings, some flightless while other have the ability of flight. The smallest bird on record is the bee hummingbird measuring at a very small 2 inches and ranging all the way up to the very large ostrich measuring at 9 feet. Birds are descendants of extinct dinosaurs with feathers, which make them the only dinosaurs still existing.
All species of birds have wings but the development of some wings don’t allow those birds to fly, such as penguins. Some birds such as parrots are among the most intelligent animals, even where some birds are even to speak in phrases to humans.
