They hunt day and night usually staying close to the ground, they fly, hover, walk, or run, seizing prey in their talons. When not hunting for food they sleep on dirt mounds at their burrow entrances.
They are mostly monogamous and breed close together in loose colonies. Females stay in or near the nest burrow until chicks fledge, while males tend to stand guard at a nearby burrow or perch. Males defend their territories against other males by vocalizing, displaying in a weaving crouch with feathers fluffed, or chasing and attacking with outstretched talons.
