Recommended citation for factsheets for more than one species: BirdLife International (2023) IUCN Red List for birds. Increasing Extent of occurrence (breeding/resident):īirdLife International (2023) Species factsheet: Dryocopus martius. For these reasons the species is evaluated as Least Concern. We focused upon habitat use and home range size variation in an alpine population of the Black Woodpecker Dryocopus martius. The Black Woodpecker is a personal account written for all, whether professional or amateur, who are interested in woodpeckers and indeed all forest birds. The population size is extremely large, and hence does not approach the thresholds for Vulnerable under the population size criterion (10% in ten years or three generations, or with a specified population structure). Justification of Red List category This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence 30% decline over ten years or three generations). Wood chips are removed from the hole, by tossing them away with string sideway movements.Click here for more information about the Red List categories and criteria The nest-chamber is dug out into soft wood at the end of the deep tunnel. The Black Woodpecker may reuse old hole in tree or telephone pole. The entrance is oval and vertical (13 x 8 cm), and the cavity depth may reach up to 60 cm. They need almost two weeks to excavate the hole in tall tree, usually between 5 and 10 metres above the ground, sometimes higher. The laying occurs from mid-March to mid-May. The flight is usually slow, clumsy, with the head raised.īreeding season starts as soon as mid-January, due to long pair-formation and selection of the nest-site. The Black Woodpecker flight action is fluttery and irregular over long distances, but it is more undulating during shorter flights and before landing. Some altitudinal movements are reported in winter in mountainous regions. Northern populations are only partially migratory. The Black Woodpecker is resident in most parts of its wide range. The woodpecker removes the bark and takes a look at larger pieces. The Black Woodpecker chisels deep, elongated, rectangular holes into tree trunks, in order to reach invertebrates hidden in burrows in the wood. It performs clumsy hops when foraging on the ground. They climb straight on trunks and large branches, and rarely perches crosswise. They forage low on tree trunks and at base of trees on the ground. It often feeds solitary but both partners keep in loose vocal contact. Black-backed Woodpeckers have solid black upperparts, black tails with white outer tail feathers, light breasts, and dark barring on their sides and flanks. It also takes wood-boring beetles and bark beetles and their larvae, and other arthropods, and occasionally snails. The Black Woodpecker feeds mainly on ants and their brood. This species is visible from lowlands up to 2000 metres of elevation, but it occurs usually below 1200 metres, higher in Asia (1700-2000m) and China (2400m). Seven breeding species occur in Pennsylvania and one, the black-backed woodpecker (Picoides arcticus) of northern boreal forests, is an occasional visitor in winter. Outside breeding season, it can be seen in open areas, forest clear-cuts, and sometimes vicinity of cities. The Black Woodpecker frequents mature broadleaved or coniferous forests and large woodlands, and is also seen at forest edges. At nest, both adults perform loud, rhythmic tapping. The black-backed woodpecker ( Picoides arcticus ), also known as the Arctic three-toed woodpecker, is a medium-sized woodpecker (23 cm (9.1 in) long) inhabiting the forests of North America. Softer sounds can be heard “kyak” or “rirrirrir”.ĭrumming can be long and the male drums more frequently. The alarm call is “kiyak”.ĭuring the breeding season, we can hear long series of more melodious notes “kweekweekweekwek-wik wik”. The flight call is a series of loud, piercing notes “prree-prree-prree-prree…” but it may also give softer “krük-krük-krük”. Medium-sized, mostly black woodpecker with single white cheek stripe and barred flanks. The Black Woodpecker’s territorial call is more metallic and higher-pitched than that of Eurasian Green Woodpecker “klee-klee-klee-klee…” or drawn-out “klee-eh” when perched. Two young birds with black feather peeking from nest. This one is blacker and has more glossy plumage. Black woodpecker, dryocopus martius, mother feeding chicks on tree in forest. martius (here described and displayed) is found in N Palearctic in Europe, from Spain, France and Scandinavia, S to Balkans and N Turkey, and E across Asian taiga, to Kamchatka, Sakhalin and Japan, NE China and Korea, and also Caucasus and N Iran.ĭ.m. The eyes are often bluish-grey and the bill is paler with grey tip.ĭ.m. The red head patch is duller or paler with dark feather bases. The juvenile is duller than adults, more sooty-black with paler grey throat. The female is similar with less glossy plumage and reduced red head patch only present on the hindcrown.
