This species, which is found throughout the British Isles, though less common than the Green Woodpecker, "is," says Gosse, "much more strictly an arboreal bird than that species. It climbs with great ease and dexterity, traversing the trunks and limbs of trees in all directions--perpendicularly or horizontally--and digging with great diligence and effect into the bark and wood for insects. In Kensington Gardens, London, where this bird is quite common, it usually keeps about the highest branches of lofty trees, and the loud tappings of its carpentry may frequently be heard; though a fair sight of its person is difficult to obtain, as it dodges from side to side of the trunk or branch on which it happens to be with much cunning and adroitness whenever an observer approaches. It does not, however, confine itself entirely to the tall trees, for it occasionally alights on pollards, as well as on the rails and posts of fences, where, in the accumulated moss and lichen, or in the various holes and crevices, it finds a harvest of spiders, ants, caterpillars, and other insects; while in the season it varies its bill of fare by stealing cherries, plums, and other fruit." Colonel Montague gives the following instance of the devotion of the female of this species for her young:--"It was with difficulty that the bird was made to quit her eggs; for, notwithstanding a chisel and mallet were used to enlarge the hole, she did not attempt to fly out until the hand was introduced, when she quitted the tree at another opening." The eggs, from five to seven in number, are pure glossy white. THE HARLEQUIN WOODPECKER. The HARLEQUIN WOODPECKER (_Piculus minor_), as the least of all European Woodpeckers is called, differs from its congeners in the comparative shortness of its slightly conical beak, rounded tail, and the very peculiar coloration of its plumage. In the male the brow is yellowish grey, the crown of the head bright red, the upper part of the back entirely black, and the lower portion white, streaked with black; the whole of the wings are striped black and white, and relieved by a black line that passes along the sides of the neck, which it thus divides from the grey belly, which is longitudinally streaked with black at its sides. The centre tail-feathers are black, and those at the exterior of a whitish hue, striped with black. The female is without the red patch on the head; the young resemble the mother, but are somewhat duller in their hues. In all the eye is yellowish brown or fiery red, the beak lead-grey, with black tip and culmen, and the foot dark grey. This species is six inches long, and from eleven to eleven inches and a half broad; the wing measures two inches and three-quarters, and the tail two inches and a quarter.
