Woodpecker

Woodpeckers are real tree- dwellers, where they dig for insects and grubs. The loud drumming made by the beak is a male's warning to other males, and also an invitation to a female. A hole is bored in a tree for a nest. Common in Europe are the Lesser Spotted (no larger than a sparrow) the Great Spotted and the Green Woodpeckers. The largest European species is the Black Woodpecker, as big as a crow. Largest of all is the Ivory – billed Woodpecker of Mexico, fifty centimeters long. Some gaudily coloured birds related to woodpeckers are the toucans of South America, which have enormous beaks and look top-heavy. In fact the beak is quite light, and a toucan can hold and play with a grape or an egg without damaging it.
