Abstract:

Franklin documented the existence of a breeding population of great gray owls (Strix nebulosa) in southeastern Idaho and northwestern Wyoming and documented aspects of the owl's breeding biology between 1980 and 1983. A total of 36 nesting territories and 31 potential breeding territories were identified. Northern pocket gophers (Thomomys talpoides) and voles (Microtus spp.) constituted 57.9 and 34.1 percent of the diet, respectively. Franklin suggests that abundance and availability of prey determined use of nest sites, nesting habitats, and the types of prey taken by great gray owls.
