black woodpecker

The black woodpecker (Dryocopus martius) is a species of bird found in the coniferous and beech woodlands of temperate Eurasia. It is one of the larger woodpecker species, measuring about 46 cm (18 inches) in length. Woodpeckers, in general, are known for their ability to probe for insects in tree bark and for excavating nest holes in deadwood. They are found nearly worldwide, with the exception of Australia and New Guinea, and are most abundant in South America and Southeast Asia. Most woodpeckers are not migratory and spend their lives in trees, though some species feed on fruits, berries, or sap. The ability of woodpeckers to excavate their own nest holes is considered a significant factor in their success, allowing them to exploit niches unavailable to other birds.12
