Survey design for broad-scale, territory-based occupancy monitoring of a raptor: Ferruginous hawk (Buteo regalis) as a case study

Publications Posted on: October 02, 2019
Given the uncertain population status of low-density, widely-occurring raptors, monitoring changes in abundance and distribution is critical to conserving populations. Nest-based monitoring is a common, useful approach, but the difficulty and expense of monitoring raptor nests and importance of reliable trend data to conservation requires that limited resources are allocated efficiently.

Re-occupancy of breeding territories by ferruginous hawks in Wyoming: Relationships to environmental and anthropogenic factors

Publications Posted on: June 15, 2016
Grassland and shrubland birds are declining globally due in part to anthropogenic habitat modification.

Research on ferruginous hawks in Wyoming

Media Gallery Posted on: October 09, 2015
Over the past decade and a half, raptors nesting in prairie ecosystems have been subject to sharp increases in nearby energy development activity. From 2000 to 2006, the number of oil wells in Wyoming increased by 73 percent, and the number of natural gas wells by 318 percent. The management of avian species that depend on sage-steppe ecosystems is an important emerging issue across the western United States, in part due to this increased energy development.

Response of nesting ferruginous hawks to energy development

Science Spotlights Posted on: May 20, 2015
Over the past decade and a half, raptors nesting in prairie ecosystems have been subject to sharp increases in nearby energy development activity. This research documents how nesting ferruginous hawks forage in oil and gas energy fields based on GPS telemetry. The purpose is to help managers and companies reflect conservation needs of this species in the management and arrangement of energy-development infrastructure.   

Ferruginous Hawk (Buteo regalis)

Publications Posted on: September 16, 2010
The Ferruginous Hawk (Buteo regalis) is New Mexico's largest buteo. Sibley (2000) gives an average length of 58.4 cm (23 in) for the species, a wingspan of 1.4m (4.6 ft), and a weightof1.59 kg (3.5 lb). Respectively, these measurements are 21%, 14%, and 46% greater than similar measurements for the Red-tailed Hawk (Buteo jamaicensis).
