North America
(2003) report the mean nesting and basal areas for goshawks breeding in northern Wisconsin were 31 ha (range = 6-101 ha) and 25 m 2/ha (range = 17-36 m 2/ha), respectively. Additionally, 41% of nests were in trembling aspen (Populus tremuloids), 17% in other deciduous trees, and a small percentage in pine plantations. The Federal BBS information can be obtained at http://www.mbr-pwrc.usgs.gov/bbs/bbs.html by clicking on Trend Estimates and selecting the species in question. All estimates are for time period (1966-2005). Continue on 270 for 2.2 miles until you come to a sign marked Fire Point and FR 223. Turn right and follow this road for 14 miles out to the point. Along the way you might catch a glimpse of a Norther Goshawk. It is thought that the Kaibab Plateau once harbored the densest Northern Goshawk population in North America. At 25 miles, you will come to the Kaibab Lodge on your right, and, a few hundred yards farther, the entrance to De Motte Park campground, also on your right. The elevation here is about 8,800 feet. De Motte Park campground is a good place to find Three-toed Woodpeckers. It is a permanent resident in North America from Alaska east to Labrador and Newfoundland and south throughout much of the western U.S., along the northern tier of states from Minnesota to New York, in northern New Jersey and New England, and in the Appalachian Mountains of Maryland and West Virginia. Nests were constructed an average 10.9 meters above the ground and were usually located near water (232 m) or a clearing (85 m) (Kirkley 1996). Range-wide nest site characteristics are similar. Almost no information is available regarding Northern Goshawk foraging strategies in Montana. View of the Vermillion Cliffs from the Kaibab Plateau. The Kaibab Plateau is located in northern Arizona in the United States. The plateau, part of the larger Colorado Plateau, is bordered on the south by the Grand Canyon and reaches an elevation of 9200 feet (2817 m) above sea level. The highest point has an elevation of 9,200 feet. The plateau is bounded on the south by the Grand Canyon of the Colorado River, the elevation in this southern area of the plateau varies from 8,800 feet to slightly less than 6,000 feet. 2001), and large clear-cut areas also encourage competitive species to move in and displace goshawks from established nesting areas (Erdman et al 1998, La Sorte et al. 2004). Goshawks appear to select late-successional forest stands for nesting (e.g., Reynolds et al. 1982).

All estimates are for time period (1966-2005). De Motte Park campground, located four miles from the National Park entrance, is a good central location from which to fan out and begin birding and exploring this area. It is located on Highway 67, 26 miles south of the starting point at Jacob Lake, Arizona. At 25 miles, you will come to the Kaibab Lodge on your right, and, a few hundred yards farther, the entrance to De Motte Park campground, also on your right. The elevation here is about 8,800 feet. De Motte Park campground is a good place to find Three-toed Woodpeckers. The Northern Goshawk is a fairly large hawk with a long tail having a broad, dark sub-terminal band and three to four narrower dark bands, rounded wing tips, and a conspicuous pale eyebrow. Nests were constructed an average 10.9 meters above the ground and were usually located near water (232 m) or a clearing (85 m) (Kirkley 1996). Range-wide nest site characteristics are similar. Almost no information is available regarding Northern Goshawk foraging strategies in Montana. The cool forests of the plateau are home to the Kaibab squirrel, which is endemic to the area. There are other animals such as deer, turkey, and bobcat. The Kaibab deer are particularly important because of the changes in their population during the early 1900s. The highest point has an elevation of 9,200 feet. The plateau is bounded on the south by the Grand Canyon of the Colorado River, the elevation in this southern area of the plateau varies from 8,800 feet to slightly less than 6,000 feet. Timber harvest is the main threat to nesting birds because of their preference for large trees and forest stands with high canopy cover (Squires and Reynolds 1997), although loss of forest stands to fire and bark beetles could degrade goshawk habitat. Nests were constructed an average 10.9 meters above the ground and were usually located near water (232 m) or a clearing (85 m) (Kirkley 1996). Range-wide nest site characteristics are similar. Almost no information is available regarding Northern Goshawk foraging strategies in Montana.
