Sagebrush has grown into one of the West's preeminent raptor biology outfits. We use spatiotemporal modeling to locate likely nesting locations based on species-specific attributes: canopy cover, surface water, topographical relief, and other variables are analyzed to focus survey intensity.  We have located red-shouldered hawk in the swamps of northern Wisconsin and Mexican-spotted owl in the desert of New Mexico.

To date, we have surveyed more than 70,000 acres for a variety of special-status raptors including burrowing owl, broad-winged hawk, Cooper's hawk, ferruginous hawk, prairie falcon, Mexican spotted owl, northern goshawk, red-shouldered hawk, osprey, bald and golden eagles, sharp-shinned hawk, among others. 

Our avian biologists volunteer their time surveying for and monitoring raptor nests along the Green River. Forty two nests, representing more than a dozen species, have been located or monitored since the spring of 2016.
