Influence of prey use and habitat on Burrowing Owl (Athene cunicularia) reproduction, The
Food, competition, and predation dictate habitat use (Schmutz et al. 1991) and ultimately reproduction. Avian reproduction is frequently food-limited (Wellicome 2000), and predation is the primary cause of nest failure (Martin 1993). Selection of prey and habitat features which minimize these effects should therefore enhance reproduction. We examined this issue using the Burrowing Owl, a declining species of the Great Plains.
