Abstract
Burrows are an integral part of the natural history of the Western Burrowing Owl (Athene cunicularia hypugaea), however, mammal burrows are uncommon in southern Texas where the Burrowing Owl overwinters. Seventy-two artificial burrows of 2.4 m length were monitored regularly for Burrowing Owl and other vertebrate use over two non-breeding seasons (October through March, 2001 to 2003). Six types of burrows, differing in diameter (15, 20, or 25 cm) and number of openings (two or three), were monitored. Small-diameter (15 cm) burrows accounted for 79% of all Burrowing Owl use. Burrowing Owl use of artificial burrows was not related to number of openings (p = 0.1), but diameter of openings was significant (p = 0.05). Vertebrates used all six types of artificial burrows.
