Habitat use at multiple scales by nesting gray vireos in New Mexico

Abstract

Pinon-Juniper (Pinus edulis-Juniperus spp.) woodlands cover approximately 40 million hectares of the western United States (Romme et al. 2009) and provide habitat for a diverse suite of avian species. Several U.S. Fish and Wildlife Service (FWS) Birds of Conservation Concern (BCC) depend on Pinon-Juniper habitats for breeding, including the Gray Vireo (Vireo vicinior). Gray Vireos breed within a limited range only in the hot, arid southwestern USA (Barlow et al. 1999). In New Mexico, they occupy the Pinon-Juniper habitats of foothills, canyons, mesas, and rolling hills. Their populations are disjunct, however, with most occupied sites containing few, often less than 10, territories (DeLong and Williams 2006). The New Mexico Department of Game and Fish (NMDGF) currently lists the Gray Vireo as a threatened species (NMDGF 2016).
