Red-shouldered Hawk

Red-shouldered Hawks Nesting

red-shouldered 008Male red-shouldered hawks put on an impressive courtship display for females. The male enacts a “sky dance” in which he soars while calling, then makes a series of steep dives toward the female, climbing back up in wide spirals after each descent, before finally rapidly diving to perch upon the female’s back. After copulation, the female lays her eggs in a nest which she has most likely used for several years. It is usually located below the canopy but more than halfway up a tree, generally in a crotch of the main trunk. Both male and female hawks build or refurbish the nest, adding fresh evergreen sprigs to it throughout the nesting period (eastern hemlock in pictured nest). Females do most of the incubating and brooding of the young, with the male providing food. The nestlings pictured are roughly two weeks old; in three or four weeks they will begin to climb out on branches away from the nest, in preparation for fledging.

Red-shouldered Hawks Building and Refurbishing Nests

4-5-13 red-shouldered hawk nest IMG_8573With winter temperatures still upon us, it can be challenging to find signs of spring in the hills of Vermont.  However, subtle signs do exist if you know where to look!  Notice the fresh greenery in this nest – it confirms that recent refurbishing has taken place by returning red-shouldered hawks.  Roughly two feet in diameter, a red-shouldered hawk’s stick nest is lined with moss, lichen, bark and conifer sprigs.  Other  items that have been used as building material for these raptors include ears of corn, corncobs, corn husks, tissue paper, nests of songbirds, straw, mullein, leaves, twine, various deciduous tree leaves, entire plants, dried tent caterpillar webs and plastic grocery bags. The pictured nest will serve as a nursery for two to five red-shouldered hawk chicks in about a month’s time, and as the nesting season progresses, sprays of conifers such as the hemlock sprigs you see here will continue to be added.
