When one ascends to the nest, which, by the way, is not always an easy matter, as our Beech-trees are not only very smooth, but frequently without any boughs to a considerable distance from the ground, as well as of rather large size, the female bird, if she happens to be sitting, flies off silently and alights on a neighbouring tree, to wait the result. But, should the male, who supplies her with food, and assists in incubation, be there, or make his appearance, he immediately sets up a hue and cry, and plunges towards the assailant with such violence as to astonish him. When, on several occasions, I have had the tree on which the nest was placed cut down, I have observed the same pair, a few days after, build another nest on a tree not far distant from the spot in which the first one had been.
The mutual attachment of the male and the female continues during life. They usually hunt in pairs during the whole year; and although they build a new nest every spring, they are fond of resorting to the same parts of the woods for that purpose. I knew the pair represented in the Plate for three years, and saw their nest each spring placed within a few hundred yards of the spot in which that of the preceding year was.
The young remain in the nest until fully fledged, and are fed by the parents for several weeks after they have taken to wing, but leave them and begin to shift for themselves in about a month, when they disperse and hunt separately until the approach of the succeeding spring, at which time they pair. The young birds acquire the rusty reddish colour of the feathers on the breast and shoulders before they leave the nest. It deepens gradually at the approach of autumn, and by the first spring they completely resemble the old birds. Only one brood is raised each season. Scarcely any difference of size exists between the sexes, the female being merely a little stouter.
This Hawk seldom attacks any kind of poultry, and yet frequently pounces on Partridges, Doves, or Wild Pigeons, as well as Red- winged Starlings, and now and then very young rabbits. On one or two occasions, I have seen them make their appearance at the report of my gun, and try to rob me of some Blue-winged Teals shot in small ponds. I have never seen them chase any other small birds than those mentioned, or quadrupeds of smaller size than the Cotton Rat; nor am I aware of their eating frogs, which are the common food of the Winter Falcon, an account of which you will find, kind reader, in another part of this the first volume of my Biography of the Birds found in the United States of America.
