Bechstein gives the following account of an attempt to tame the _Picus medius_, a closely-allied species. "I have," he says, "seen one of these Woodpeckers, which was reared by a lady and seemed much attached to her; it had learned to leave its cage and return, knocking hard at the window if shut out. It was very amusing to see it climbing nimbly over its mistress till it had reached her mouth. It then asked her, by light strokes of the wing, for the food she was accustomed to give it; this was generally a little meat. It disappeared one day, without any one knowing what had befallen it."
The THREE-TOED WOODPECKER (_Apternus tridactylus_), as the most striking of all the European members of this family is called, represents a group recognisable by their straight beak, which is broader than it is high, and equals the head in length. All the three toes are shorter than the tarsus; of these the outermost is the smallest, and the two others of equal length. In the wing the fourth quill is the longest. The centre feathers of the conical tail are furnished with very stiff shafts, and sharply pointed at their tip. The upper portions of the body are black, and the under side dirty white; the brow black, spotted white, and the crown of the head pale golden yellow. A white line, more or less marked with black, passes from the eyes to the middle of the back; the bridles and a second line that terminates at the throat are black; as are the markings on the sides of the belly. The quills and exterior tail-feathers are black, striped with white, and the centre tail-feathers entirely black. The eye is pearl-grey or silver-white, the beak light grey, tipped with black, and the foot dark grey. The female has the crown of the head spotted with white, instead of being yellow as in the male. The length of this species is nine and its breadth fourteen inches; the wing measures four inches and three-quarters, and the tail three inches and three-quarters.
It is at present undecided whether all such of these birds as inhabit Europe are to be regarded as identical; but if it be so the habitat of this species extends over a large portion of both the European and Asiatic continents. In the northern parts of Europe it is met with in the course of its wanderings as far north as sixty degrees north latitude, and is by no means rare; in Scandinavia, Finland, and Russia it is especially numerous, and in the country about the mouth of the Amoor is one of the commonest of birds. North America also possesses a deceptively similar or identical species. Everywhere it frequents well-wooded mountain regions, and closely resembles the Common Variegated Woodpecker in all the various particulars of its habits, movements, and means of subsistence. It is active and restless in its habits, and generally occupies the topmost branches of the trees. Its cry is loud and shrill, somewhat resembling that of some small quadruped when in great pain. Towards noon it is silent, and retires to rest in a quiet spot. Its rapid, gliding, and undulating flight is always accompanied by a succession of loud notes. The nest is usually from twenty to twenty-four inches deep, and is bored in the trunk of a sound tree. One brood of four to six pure white eggs is laid in the season.
