Burrowing owls are found throughout the western United States in open grasslands, although their population has declined due to the loss of open spaces. Visitors to Sierra Vista Open Space Preserve may be able spot these 8-inch tall birds, which have brown-tan splotched feathers and bright yellow eyes. The owls eat a variety of insects and small reptiles including grasshoppers, beetles, crickets, and lizards. Females spend one month incubating about eight eggs each year. During that time, their male partners bring them food.
