The BLACK WOODPECKERS (_Dryocopus_) comprise the largest and most powerful of the race, and are at once recognisable by the crest that adorns their head, and the prevalence of black in the coloration of their plumage. America must be regarded as the central home of these birds, as there several kinds inhabit every latitude; whilst, in the Eastern Hemisphere, but one species is met with in Europe, and few are found even in India. THE EUROPEAN BLACK WOODPECKER. The EUROPEAN BLACK WOODPECKER (_Dryocopus martius_) has the plumage of a uniform black, with the exception of the top of the head, which is of a bright crimson; in the female the bright feathers are limited to a small patch at the back of the head. The eye of both sexes is pale yellow, the beak pearl-grey, tipped with blueish grey, and the foot lead-colour. The young closely resemble the adult birds. This species is from seventeen to eighteen inches long, and twenty-eight to twenty-nine broad. The wing, in which the fifth quill is the longest, covers two-thirds of the tail, which measures from six inches to six inches and a half; the tarsus is almost entirely covered with feathers, and exceeds the centre toe and claw in length. The strong beak is broader than it is high, and straight at its culmen. Although all the wooded tracts of Europe, from sixty-eight degrees north latitude as far as Greece and Spain, are inhabited by the Black Woodpecker, it is seldom met with in England, and is but rarely seen in Holland. It also frequents Asia, as far as the northern side of the Himalayas. Everywhere fir and pine forests are its favourite resorts, even when these extend over mountain ranges; indeed, it rarely visits tracts covered with any other description of trees, except during its wanderings from one place to another. Like all other European Woodpeckers, this species does not migrate, and but rarely travels to any great distance from its native haunts. [Illustration: THE WOODPECKER TREE-CHOPPER (_Dendroplex picus_).] The Black Woodpecker is shy and retiring in its habits, and, if approached, studiously conceals itself from observation by creeping round the tree or branch on which it happens to be at work. Its food is obtained by perforating the bark or searching the fissures of trees, a process which it performs with great dexterity, the tail being habitually employed as a means of support whilst climbing. The night is passed in holes in the trunk of some old tree; and in a cavity of this description the glossy white eggs are also deposited. We learn from Temminck that the Black Woodpecker lays three eggs; and that when other food is scarce it will eat seeds or berries. Its voice somewhat resembles a harsh, loud laugh. * * * * *
