Parental care by lone male Ferruginous Hawks (Buteo regalis), Rough-legged Hawks (Buteo lagopus), and Great Horned Owls (Bubo virginianus) was limited to providing food
In three long-term studies of Ferruginous Hawks (Buteo regalis), Rough-legged Hawks (Buteo lagopus), and Great Horned Owls (Bubo virginianus), we observed rare but regular occurrences of superabundant prey at nests where nestlings were hungry, emaciated, or dead. In these cases, a male appeared to b...
