Title: Habitat Selection by Selected Breeding Passerine Birds in Pine-Oak Forests of Northern Arizona

Subject: Oak (Quercus), Ponderosa pine (Pinus ponderosa), Birds

Abstract: Forest treatments proposed to restore pre-settlement conditions for northern Arizona ponderosa pine (Pinus ponderosa) forests will dramatically alter forest structure by reducing densities of smaller diameter trees. Baseline information on habitat selection is needed to understand responses of passerine birds to these treatments. During the 1997 and 1998 breeding seasons, I examined foraging-habitat selection by 5 permanent resident species ~ hairy woodpeckers (Picoides villosus) , mountain chickadees (Poecile gambeli), white-breasted nuth atches (SUra carolinensis), pygmy nuthatches (S. pygmaea), and darkeyed juncos (Junco hyemalis) - and 3 neotropical migrants, Virginia's warblers (Vennivora virginiaey, p1umbeus vireos (Vireo plumbeus), and western tanagers (Piranga ludoviciana} , I measured and analyzed habitat selection at 2 scales, the foraging tree (third-order selection sensu Johnson 1980) and within a 0.04-ha plot centered on each foraging location (Johnson's second-order selection).
