Picamaderos Negro

Identificación

The black woodpecker measures 45 to 55 cm (18 to 22 in) long with a 64 to 84 cm (25 to 33 in) wingspan. Body weight is approximately 250 to 400 g (8.8 to 14.1 oz) on average. 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). 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. 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. The plumage of this crow-sized woodpecker is entirely black apart from a red crown. 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 juvenile black woodpecker is similar but is less glossy, with a duller red crown and a paler grey throat and bill . The piercing yellow eyes and manic, high-pitched calls of the black woodpecker have made it the villain of fairy tales throughout its range. Their voice is remarkable in that it has two different calls. One is a short single high-pitched note, a loud, whistling kree-kree-kree, done only twice in a row. The other is a screech-like shrill while in flight. 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.

Taxonomía

The black woodpecker was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the binomial name Picus martius. Linnaeus gave the locality as Europe, but this is now taken to be Sweden. The black woodpecker is now placed in the genus Dryocopus that was introduced by the German naturalist Friedrich Boie in 1826.<p>Two subspecies are recognised:

Distribución y hábitat

The range of the black woodpecker spreads east from Spain across the whole of Europe, excluding Great Britain, Ireland, and northern Scandinavia. It is also native to parts of Asia, including Korea, Japan and China, and to the Middle East, including Iran and Kazakhstan. The southern limits of this woodpecker's range are in Spain and Italy, and it has also been recorded as a vagrant in Portugal. The species is generally more uncommon and more discontinuous in distribution in the Asian part of its range.<p>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).<p>The black woodpecker is noticeably absent from the British Isles. 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.
