Summary:

Worldwide Species Action Plans

Northern Goshawk action planThe northern goshawk (Accipiter gentilis atricapillus, hereafter referred to as goshawk) has been proposed for listing several times under the Endangered Species Act and its status has been (and still is) the object of considerable litigation. It is currently not listed as a threatened species but is considered a sensitive species or a species of concern by most governmental agencies and non-governmental organizations within Region 2. Currently, there is no demographic evidence in North America (including Region 2) that the goshawk is declining. This lack of evidence can be interpreted in two ways: 1) the goshawk is not declining, or 2) it is declining but I dont have sufficient information to detect the declines. In Region 2, there is clearly insufficient data to determine population status. However, within Region 2, Partners in Flight suggest the goshawk may be declining in the Central Rocky Mountain Physiographic Region, which occurs in the extreme northwest section of the region. The basis for this conclusion is unknown but is likely based on the threat of habitat alteration to the goshawks preferred breeding season habitat. The primary threat to goshawk populations is alteration of its preferred habitat from timber management practices. Biologists and land managers have raised concerns over destruction and modification of goshawk nesting, post-fledging, foraging, and wintering habitat. Although the goshawk uses a wide range of forest communities during the breeding season, it prefers mature and old-growth forest for nesting and hunting. Its winter habitat preferences in North America are poorly understood but the limited data from North America and Europe suggest the bird can use the same habitats year-round as well as non-forested habitats at lower elevations. Although there is some evidence goshawks are resilient to forest fragmentation and can re-establish when cleared areas are reforested, the thresholds for population persistence have not been identified.
