Kingdom: Animalia
Phylum: Chordata
Subphylum: Vertebrata
Class: Aves
Order: Strigiformes
Family: Strigidae
Genus: Athene
Species: Athene cunicularia

Geographic Range

Athene cunicularia is found in North and South America. They live in the desert regions and grasslands of western North America, and also in the drier areas of Central and South America. Burrowing Owls spend their winters in Texas where they commonly breed. During the summer the owls also can be found in northern areas of the Great Plains and northern California (Snyder 2000; Interactive Broadcasting Company 1999).

Biogeographic Regions:
nearctic (native ); neotropical (native ).

Habitat

Athene cunicularia lives in burrows of open, dry grasslands, and deserts. They can also be found in airports and golf courses (Davis 2000).

Terrestrial Biomes:
desert or dune ; savanna or grassland .

Physical Description

Athene cunicularia is one of the smallest owl species. The owl, which resides primarily on the ground, has long lanky legs, a short tail, and it does not have any ear tufts. The average adult owl is between 8.5-11 inches tall and weighs about 4-6 oz. Unlike other owl species, the female burrowing owl is smaller than the male. The burrowing owl's body is generally brown with speckles of white. The owl's breast is a lighter color brown while its face is encircled in white, with tinges of sandy brown feathers. The owl has wings about the same size as its body, featherless legs, and round yellow eyes ("Interactive" 1999; Davis 2000).

Some key physical features:
endothermic ; bilateral symmetry .

Reproduction

Time to hatching
28 days (average)
[External Source: AnAge]


Burrowing owls will nest underground, either by digging its own burrow or more frequently by taking over a burrow dug by other mammals such as prairie dogs and pocket gophers. The owl lines its den with grass and roots and in April the female owl will lay about 7-9 round white eggs. After about four weeks of incubation, the eggs will hatch and the mother and father will share the responsibility of caring for the young. The young owlets will remain in their nest for about 40 days before leaving and venturing out on their own. While owlets are still in their nest, they have the capability of mimicking a rattlesnake to scare away predators (Davis 2000).

Key reproductive features:
iteroparous ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; oviparous .

Behavior

Athene cunicularia is different from other owl species in many different aspects. The owl spends most of its time on the ground and it will live together in colonies with other burrowing owls. They may hover above the ground in search for prey. The burrowing owl is diurnal, and not nocturnal like most other species of owls. The owl is also unique in that its entire head revolves in order for it to see its surroundings because its eyes are not capable of moving in the eye sockets (Britannica 2000; Snyder 2000).

Key behaviors:
flies; motile .

Food Habits

The diet of the burrowing owl consists of insects, small frogs, lizards, and rodents. The owl will eat beetles, crickets, moths, kangaroo rats, and snails. It eats different prey depending on availability in the habitat and the time of year. The owl is a keen hunter always on the look out for prey, during the day or night, and always keeping a supply of food in its burrow (Snyder 2000; "Interactive" 1999).

Economic Importance for Humans: Positive

Because of the human destruction of the burrowing owl's habitat, the owl has been decreasing in number and therefore is not abundant enough to be used for any human advantage (Snyder 2000)

Conservation Status

IUCN Red List: [link]:
Least Concern.

US Migratory Bird Act: [link]:
Protected.

US Federal List: [link]:
No special status.

CITES: [link]:
Appendix II.

State of Michigan List: [link]:
No special status.

Burrowing owl populations are declining. An insecticide used in farming was recently banned in Canada because of the harmful effects the chemical has on burrowing owls. A reintroduction program started in 1985 is trying to establish a population of these owls in Minnesota, Iowa, and South Dakota (Snyder 2000).
