Burrowing owls are a small, long-legged species of owl that spends the majority of its time on the ground. They are native to open grassland, prairie, and desert habitats and range from southern Canada (where they are considered an endangered species) to the drier habitats of South America. They have also been found nesting in man-made structures and in close proximity with people on golf courses, campuses, and suburbs. Burrowing owls differ from most owls in a variety of ways. They are primarily terrestrial and nest underground while the majority of owls are cavity nesters or use the nest of other birds, such as crows or hawks. Burrowing owls are fairly social and sometimes form loose colonies in the non-breeding season, while other owls are solitary when not breeding. Burrowing owls are also fairly active throughout the day (although most hunting takes place at dawn and dusk) while most, but not all, owls are nocturnal predators.
