Abstract

Diets of coyotes (Canis latrans) on the Rob and Bessie Welder Wildlife Refuge (WWR) in south Texas were determined from analyses of scats collected during 1961-62, 1973-74, 1975-76, and 1978-79. Diets varied among years due to successional changes in vegetation and changes in prey abundance. Coyote diets also varied seasonally, reflecting changing abundances of a wide variety of food items, differential vulnerability of prey, effects of plant phenology, and weather conditions.
