Washington, DC: Bureau of Land Management, 1977. — 12 p.The Accipiters, or bird hawks, are long-tailed hunters with short rounded wings that enable them to fly fast and have high maneuverability. They feed mainly on small birds taken on the wing and on small mammals. Included in the Accipiter group are the goshawks, Cooper's hawks, and sharp-shinned hawks. They are less commonly observed than other hawks because of their somewhat secretive habits and the fact that they are normally found in shrubby or woodland areas or, in the case of the goshawk, in coniferous forests. Short glimpses may be had as the bird flashes through the trees or swoops on prey in the margins of woodlots. There is evidence in recent years that all accipiters may be decreasing in numbers in several parts of their range. Because of this, it has become increasingly important that land managers attempt to learn more about their habitat requirements and to provide for their needs, whenever possible, in proposed or on-going land management activities.
