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.
The GIANT WOODPECKERS (Campephilus), a group comprising the largest members of the family, inhabit America. These birds are characterised by their powerful body, large head, and long, thin neck. Their beak is long, straight, and strongly formed; their feet muscular, and the tarsi unfeathered. Of the toes, the outermost of the hinder pair exceeds the rest in length. The wings and tail are long, the third and fourth quills of the former being the longest. The plumage is black, marked with white. The feathers on the head form a crest, which in the male is of considerable size, and of a red colour.
THE EUROPEAN BLACK WOODPECKER (Dryocopus martius).
Two species of Giant Woodpeckers are worthy of special notice, named respectively the IMPERIAL and the IVORY-BILLED WOODPECKERS.
THE IMPERIAL WOODPECKER.
The IMPERIAL WOODPECKER (Campephilus imperialis) is almost entirely black. A stripe on the shoulders, the tip of the hinder quill, and the lower wing-covers are white, the latter spotted with black on the exterior edge; the crest of the male is scarlet, and that of the female black. This species is above twenty-five inches long; the wing measures twelve and the tail nine inches.
