Abstract:Brushpiles are commonly recommended to provide cover for wildlife, yet little quantitative information exists concerning wildlife use of brushpiles or designs that promote wildlife use. We studied bird use of brushpiles in California from 1986 to 1988. Although 29 species used brushpiles, golden-crowned sparrows (Zonotrichia atricapilla), rufous-sided towhees {Pipilo erythrophthalmus), white-crowned sparrows (Zonotrichia leucophrys), California quail (Callipepla californica), brown towhees (Pipilo fuscus), and Bewick's wrens (Thryomanes bewickii were most frequently encountered. High-use brushpiles had greater area and height, were located closer to blackberry (Rubus sp.) brambles, and consisted of fewer logs and more branches and limbs than low-use brushpiles. A logistic regression model correctly classified 79% of the brushpiles as high or low use for songbirds. A logistic regression model for quail alone correctly classified 69% of the brushpiles. Most (73%) high-use quail brushpiles also were high-use songbird brushpiles.
