These winter nights, against my window-pane Nature with busy pencil draws designs Of ferns and blossoms and fine spray of pines, Oak-leaf and acorn and fantastic vines, Which she will make when summer comes again— Quaint arabesques in argent, flat and cold, Like curious Chinese etchings.... By and by, Walking my leafy garden as of old, These frosty fantasies shall charm my eye In azure, damask, emerald, and gold. —Thomas Bailey Aldrich. THE HAWKS. Among the birds that are most useful to man may be classed the Hawks. They, with the vultures, the eagles and the owls, belong to the bird order Raptores, or birds of prey. Unlike the vultures the Hawks feed upon living prey while the former seek the dead or dying animal. The vultures are often called “Nature’s Scavengers,” and in many localities they have been so carefully protected that they will frequent the streets of towns, seeking food in the gutters. The family Falconidae, which includes the Hawks, the falcons, the vultures, the kites, and the eagles—all diurnal birds of prey—numbers about three hundred and fifty species, of which between forty and fifty are found in North America. The remainder are distributed throughout the world. The flight of the Hawks is more than beautiful, it is majestic. Even when perched high in the air on the top of a dead monarch of the forest, there is a silent dignity in their pose. It is from these perches that some of the species watch the surrounding country for their prey, swooping down upon it when observed and seizing it in their long, sharp and curved claws. Their food is almost invariably captured while on the wing. The bill, which is short, hooked and with sinuate cutting edges, is used for tearing the flesh of its victim into shreds.
