Birds in courtship may repeatedly fly up, hover, and descend. On ground near nest burrow, male feeds female; members of pair nibble at each other's bills and preen each other's feathers. Nest site is in burrow in ground, in area surrounded by bare soil or short grass. Florida birds usually dig their own burrows, but those in west usually use old burrow left by prairie-dogs, ground squirrels, kangaroo rats, armadillos, or other animals. Burrows excavated by the owls may be up to 6-10' long, with nest in chamber at end. May line burrow entrance and nest chamber with cow manure, but no real nest built. Eggs: Typically 7-10 in west, 4-6 in Florida; can range from 3 to 12. Eggs white, becoming nest-stained. Incubation by female only, 28-30 days; male brings food for female during incubation. Young: Female remains with young most of time at first; male brings food, and female feeds it to young. After 1-2 weeks, female begins hunting also. Young may leave nest at about 6 weeks or sometimes earlier, but not capable of strong flight at first. 1 brood per year, sometimes 2 in Florida.
