Frequents open places, heaths, plains, and marshes, and is not found in the woodlands. Its flight is graceful, not high above the ground, and it will hover every now and again when quartering. It feeds on small mammals and birds, insects, reptiles, etc, and like its allies it feeds largely on the eggs of ground-nesting birds. Its nest is a depression in the ground, frequently in a damp locality, and consists merely of a few sticks and heather-bents with a little dry grass. The eggs, 4 to 5 in number, are generally deposited late in May, and are bluish white, usually unmarked, and measure about 1.81 by 1.39. I have, however, seen eggs slightly, and others somewhat boldly, marked with dark red.
