ABSTRACT
We analyzed Barn Owl (Tyto alba) castings collected during August 1974 to May 1977 from birds inhabiting an urbanized Sonoran desert community. Prey species composition and age (adult versus juvenile) varied seasonally. The cotton rat (Sigmodon arizonae) was the most frequent prey, comprising 38.8% of the overall diet.
