The black woodpecker (Dryocopus martius) is a large woodpecker that lives in mature forest across the northern Palearctic. It is the sole representative of its genus in that region. Its range is expanding in Eurasia. It does not migrate. This species is closely related to, and fills the same ecological niche in Europe as, the pileated woodpecker of North America. The species is generally more uncommon and more discontinuous in distribution in the Asian part of its range. The black woodpecker is mainly found in forested regions, with a preference for extensive, mature woodland, including coniferous, tropical, subtropical and boreal forests. It is very widespread throughout mountainous and lowland forests. It is more likely to occur in marginal woods near human habitations during the non-breeding season. This species has been observed at elevations between 100 and 2,400 m (330 and 7,870 ft). The woodpecker feeds by using its bill to hammer on dead trees to dig out carpenter ants and wood-boring beetle grubs. The selection of foods is relatively predictible, narrow and consistent in this species. Like all woodpeckers, this species has a specially adapted neck containing very strong muscles, which allow it to endlessly hack away at tree bark.
