Food habits of Mexican Spotted Owls in Arizona

Abstract

The Spotted Owl (Strix occidentalis) is most common in mature and old-growth coniferous forests throughout much of its range (Forsman et al. 1984, Laymon 1988, Ganey and Balda 1989a, Thomas et al. 1990). Proximate factors underlying habitat selection in Spotted Owls are understood poorly. Abundance and availability of food, however, may be a key factor influencing habitat selection in birds in general (Hilden 1965) and in owls in particular (Southern and Lowe 1968).
