Although habitat requirements of true prairie Buteo species, Swainson's (Buteo swainsoni) and ferruginous hawks (B. regalis), are relatively well identified, little is known about habitat use by red-tailed hawks (B. jamaicensis) in this ecoregion. This study, evaluating productivity and habitat selection of red-tailed hawks breeding in aspen parkland, was conducted on Prairie Habitat Joint Venture (PHJV) assessment sites in central Saskatchewan in 1997 and 1998. Red-tailed hawk nesting densities and productivity were determined at three sites. Home ranges were mapped. Macrohabitat use and avilability data were generated from digitized aerial photographs of PHJV assessment sites using a Geographic Information System.Microhabitat variables were measured in 0.04 ha plots centered on nests and random locations.
