Rh claws and tail. If they intend to settle on a branch, which they as frequently do, they do not previously rise; but in either case, no sooner has the bird alighted, if it be not pursued or have suspicions of any object about it, than it immediately nods its head, and utters its well-known note, "Flicker." It easily moves sidewise on a small branch, keeping itself as erect as other birds usually do; but with equal ease does it climb by leaps along the trunk of trees or their branches, descend, and move sidewise or spirally, keeping at all times its head upwards, and its tail pressed against the bark as a support.

On the ground, where it frequently alights, it hops with great ease. This, however, it does merely to pick up a beetle, a caterpillar, a grain of corn dropt by a squirrel from the ear in the fields, or to enable it to examine the dead roots of trees, or the side of a prostrate log, from which it procures ants and other small insects. It is also fond of various fruits and berries. Apples, grapes, persimons and dogwood berries seem quite agreeable to it, and it does not neglect the young corn of the farmer's field. Even poke-berries or huckleberries answer its purpose at times, and during winter it is a frequenter of the corn-cribs.

In this species, as in a few others, there is a singular arrangement in the colouring of the feathers of the upper part of the head, which I conceive it necessary for me to state, that it may enable persons better qualified than myself to decide as to the reasons of such arrangement. The young of this species frequently have the whole upper part of the head tinged with red, which at the approach of winter disappears, when merely a circular line of that colour is to be observed on the hind part, becoming of a rich silky vermilion tint. The Hairy, Downy and Red-cockaded Woodpeckers are subject to the same extraordinary changes, which, as far as I know, never reappear at any future period of their lives. I was at first of opinion that this change appeared only on the head of the male birds, but on dissection I found it equally affecting both sexes. I am induced to believe, that, in consequence of this, many young Woodpeckers of different species have been described and figured as forming distinct species themselves. I have shot dozens of young Woodpeckers in this peculiar state of plumage, which, on being shewn to other persons, were thought by them to be of different species from what the birds actually were. This occurrence is the more worthy of notice, as it is exhibited on all the species of this genus on the heads of which, when in full plumage, a very narrow line exists.
