ABSTRACT Harris's Hawks (Parabuteo unicinctus) are cooperative breeders, and groups of more than a pair have been reported from Arizona (49% to 83%) and New Mexico (51%). However, two studies (Griffin 1976, Brannon 1980) suggested that they bree[...]

ABSTRACT Sexual dimorphism in birds may express itself as differences in body size, plumage, color and/or behavior. Many species are monomorphic in color, which makes sex determination difficult in the field. In order to develop a tool to distin[...]
