THE THREE-TOED WOODPECKER.
PiCUS TRIDACTYLUS, LiNN.
PLATE CXXXII. Male and Female.
This curious species of Woodpecker is found in the northern parts of the State of Massachusetts, and in all portions of Maine that are covered by forests of tall trees, in which it constantly resides. I saw a few in the Great Pine Forest of Pennsylvania, and my friend, the Rev. John Bachman, observed four near the Falls of Niagara, about twelve years ago, and is of opinion that some may breed in the upper part of the State of New York.
It is a restlessly active bird, spending its time generally on the top- most branches of the tallest trees, without, however, confining itself to pines. Although it cannot be called shy, its habitual restlessness renders it difficult of approach. Its movements resemble those of the Red-cock- aded Woodpecker, but it is still more petulant than that bird. Like it, it will alight, climb along a branch, seek for insects there, and in a very few moments remove to another part of the same tree, or to another tree at more or less distance, thus spending the day in rambling over a large extent of ground. Its cries also somewhat resemble those of the species above mentioned, but are louder and more shrill, like those of some small quadruped suffering great pain. During the middle hours of the day it becomes silent, and often retires to some concealed place to rest a while. In the afternoon of warm days, it very frequently makes sorties after fly- ing insects, which it seems to secure in the air with as much ease as the Red-headed Woodpecker. Besides insects, it also feeds on berries and other small fruits.
Its flight is rapid, gliding, and deeply undulated, as it shifts from one place to another. Now and then it will fly from a detached tree of a field to a considerable distance before it alights, emitting at every glide a loud shrill note. When alighted, the rolling tappings of its bill against a dead and dried branch are as sonorous as those of the Redhead. I never saw one on the ground, but I have not unfrequently met with them searching the decayed wood of a prostrate tree.
The nest of this species is generally bored in the body of a sound tree, near its first large branches. I observed no particular choice as to the
