Abstract
Hunting methods used by 2 adult male ferruginous hawks [Buteo regalis] in southern Idaho [USA] were studied during the nesting seasons of 1974 and 1975. The birds hunted from a perch, from the ground, from low-altitude (active) flight and from high-altitude (soaring) flight. The hawks captured prey on 16.6% of their strikes, but their success ratios varied significantly with hunting method. Each bird struck about 7 times per hour of hunting time and caught about 1 prey item per hour. The hawks'' use of hunting methods seemed to be related to the number of captures they made per unit of energy expended.This publication has 20 references indexed in Scilit:
