Habitat use by breeding male Northern Goshawks in northern Arizona
I radio-tagged and followed 5 and 9 male Northern Goshawks (Accipiter gentilis atricapillus) during the breeding seasons of 1991 and 1992, respectively, to evaluate their use of different forest conditions in managed ponderosa pine (Pinus ponderosa) forests. Sufficient data for habitat analyses were...
