Burrowing Owls
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. They nest and roost in burrows, such as those excavated by prairie dogs. Unlike most owls, burrowing owls are often active during the day, although they tend to avoid the mid-day heat. Most hunting is still done at dusk or at night, when their owl apomorphies are most advantageous.
Burrowing owls are able to live for at least 9 years in the wild and over 10 years in captivity. 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 domesticated cats and dogs.
Description
Burrowing owls have bright yellow eyes. The beak can be yellow or greenish depending on the subspecies. The legs are incompletely feathered and 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.
