The Burrowing Owl (Athene cunicularia) is a small, long-legged owl found throughout open landscapes of North and South America. Burrowing owls can be found in grasslands, rangelands, agricultural areas, deserts, or any other dry, open area with low vegetation (Lewis 2005). They may live in burrows such as those abandoned by prairie dogs. Unlike most owls, burrowing owls are often active during the day. However, most hunting is done at dusk or at night.

Burrowing owls are able to live for at least 9 years in the wild and over 10 years in captivity.[citation needed] They are often killed by vehicles when crossing roads, and have many natural enemies, including badgers, coyotes, and snakes. They are also killed by both feral and domestic cats and dogs.

Burrowing owls have bright yellow eyes. The bill can be yellow or greenish depending on the subspecies. The legs are incompletely feathered, and the toes are grayish in color. They lack ear tufts and have a flattened facial disc. The owls have prominent white eyebrows and a white "chin" patch which they expand and display during certain behaviors.

Adult owls have brown upperparts with white spotting. The breast and belly are white with variable brown spotting or barring. Juvenile owls are similar in appearance, but they lack most of the white spotting above and brown barring below. Also, the young owls have a buff bar across the upper wing and their breast may be buffy rather than white.

Males and females are similar in size and appearance. However, adult males sometimes appear lighter in color because they spend more time outside the burrow during daylight, and their feathers become sun-bleached. The average adult is slightly larger than an American Robin, at 25 cm (10 inches) length, 53 cm (21 inches) wingspan, and 170g (6 oz) weight (Lewis 2005).

Vocalizations - The typical "who who" call of a burrowing owl is associated with territory defense and breeding, often given by adult males to attract a female to a promising burrow. They also make other sounds, which are described as chucks, chattering, and screams. These sounds are usually accompanied by an up and down bobbing of the head. When alarmed, young birds will give a hissing call that sounds like a rattlesnake (Haug et al. 1993).

Before European colonization, burrowing owls probably inhabited every suitable area of the New World, but they have experienced some restrictions in distribution since. They range from the southern portions of the western Canadian provinces through southern Mexico and western Central America. They are also found in Florida and many Caribbean islands. In South America, they are patchy in the northwest and through the Andes, but widely distributed from southern Brazil to Patagonia and Tierra del Fuego.

Burrowing owls are year-round residents in most of their range. Birds that breed in Canada and northern USA usually migrate south to Mexico and southern USA during winter months.
