Habitat Burrowing Owl Athene cunicularia By: Blanca Piñon-Lozano Burrowing owls are monogamous for the most part, though some male owls will have two mates. The male owl coos and does aeronautical stunts in a bid to get the females attention. Once she does, the courtship moves quickly. Sometimes the couple may build their own burrow that extends 4-8 feet underground, but most often they take up residence in the discarded burrow of a rodent or reptile. They’ll fix up the burrow with grass clippings and manure from other animals. The manure is used to conceal the odor of their presence in the burrow, but also to attract insects which serve as a meal for the mother incubating her eggs. The baby owls will hatch about 30 days after their mother lays her eggs. The clutch size averages about seven eggs, though it can be as large as 12. Burrowing owls sexually mature at 1 year of age. Phylogeny: Burrowing owls are deutorostomes, from the phylum chordata which are characterized by a notochord, hallow nerve cord, pharyngeal gill slits and a post anal tail. They originated in Quercy, France and spread throughout North America, Mexico, Brazil, and the Galapagos Islands. The burrowing owl is a small ground dwelling owl with long legs. This little owl has sandy brown feathers mixed with white. They have a round head, no ear tufts, white eyebrows and bright yellow eyes. They have a prominent white chin stripe. There is little color difference between males and females, except during breeding season, the females are darker, possibly due to extended nesting periods in the burrow.

Feeding Habits Burrowing Owls primarily feed on insects and small mammals, but they will also eat reptiles and amphibians. These owls are quite versatile in the ways they capture prey; They chase grasshoppers and beetles on the ground, use their talon to catch large insects in the air, they hover in mid air before swooping down on unsuspecting prey. They are primarily active at dusk and dawn, but will hunt all day if it has Taxonomy Interesting fact: The Burrowing owl breaks its prey’s neck with sharp blows from its large hooked beak. When alarmed, young birds will make a hissing call that sounds like a rattlesnake.
