The black woodpecker is a fairly widely distributed woodland species and can successfully breed in most areas where extensive woodland is left. After 18 to 35 days, the young black woodpeckers will leave the nest, staying with the adults for another week. The nestlings may fight their way to the entrance of the nest in order to be fed first. The breeding pair take it in turns to incubate the eggs, also sharing duties of feeding and brooding the chicks once they have hatched. The nest hole is usually dug in a live poplar or pine tree. When the nest is ready, the female lays a single clutch of two to eight eggs, the average being four to six. It not only provides habitats for other species, but also controls populations of wood-boring insects, helping to protect the trees. The black woodpecker's excavations provide homes for many other species of bird and mammal, and is therefore considered to be a "keystone" species in many of its habitats throughout its range. Once a hole has been made, the black woodpecker chips downwards through the trunk of the tree, creating a nesting chamber, the only lining being the woodchips created throughout the process. The woodpecker will more than likely choose for its nest a tree with a fungal disease, such as heart rot, although some will utilise a living, healthy tree. In order to position itself correctly, it has short, stumpy legs, as well as long, sharp claws and very stiff tail feathers. Due to the size of its bill and large size and great physical power of this bird, it can access prey fairly deep within a tree. Like all woodpeckers, this species has a specially adapted neck containing very strong muscles, which allow it to endlessly hack away at tree bark. The selection of foods is relatively predictable, narrow and consistent in this species. The woodpecker feeds by using its bill to hammer on dead trees to dig out carpenter ants and wood-boring beetle grubs. Approximately 80 sightings of the species in the UK have been reported, but some of these are disputed, though the proximity of the British Isles to the species' range in Western Europe means that the species may cross over on a regular basis. The black woodpecker is noticeably absent from the British Isles. This species has been observed at elevations between 100 and 2,400 m (330 and 7,870 ft). It is more likely to occur in marginal woods near human habitations during the non-breeding season. It is very widespread throughout mountainous and lowland forests. The black woodpecker is mainly found in forested regions, with a preference for extensive, mature woodland, including coniferous, tropical, subtropical and boreal forests. The species is generally more uncommon and more discontinuous in distribution in the Asian part of its range. The southern limits of this woodpecker's range are in Spain and Italy, and it has also been recorded as a vagrant in Portugal. It is also native to parts of Asia, including Korea, Japan and China, and to the Middle East, including Iran and Kazakhstan. The range of the black woodpecker spreads east from Spain across the whole of Europe, excluding Great Britain, Ireland, and northern Scandinavia. Unlike other woodpecker species, the black woodpecker does not have a dipping, bounding flight, but instead flies with slow, unsteady-seeming wing beats with its head raised. The other is a screech-like shrill while in flight. One is a short single high-pitched note, a loud, whistling kree-kree-kree, done only twice in a row. Their voice is remarkable in that it has two different calls. The piercing yellow eyes and manic, high-pitched calls of the black woodpecker have made it the villain of fairy tales throughout its range. ![]() The juvenile black woodpecker is similar but is less glossy, with a duller red crown and a paler grey throat and bill. In males, the entire crown is red, but in females only the top hindcrown is red, with the rest of the body all black. The plumage of this crow-sized woodpecker is entirely black apart from a red crown. The closely related pileated and white-bellied woodpeckers also broadly overlap in size with the black woodpecker, but both are somewhat smaller in average and maximal size and mass. It is easily the largest woodpecker in its range and is second in size only to the great slaty woodpecker amongst the woodpecker species certain to exist (with the likely extinction of the largest and second largest woodpeckers), although its average mass is similar to that of the Magellanic woodpecker of South America. ![]() ![]() Among standard measurements, the wing chord is 22.7 to 26 cm (8.9 to 10.2 in), the tail is 15.9 to 17.3 cm (6.3 to 6.8 in), the very long bill is 5 to 6.7 cm (2.0 to 2.6 in) and the tarsus is 3.6 to 4 cm (1.4 to 1.6 in). Body weight is approximately 250 to 400 g (8.8 to 14.1 oz) on average. The black woodpecker measures 45 to 55 cm (18 to 22 in) long with a 64 to 84 cm (25 to 33 in) wingspan.
