Habitat Selection in Birds: The Roles of Vegetation Structure, Competitors, and Productivity

Although bird habitat preferences are closely related to vegetation structure, food availability is further affected by both competitor species and independent variation in insect abundance related to variable climate. In Arizona woodlands, changes between years in birds species numbers, identities, and densities modify the consumer community to match variable food resources.
