A habitat-based approach to determining the effects of drought on aridland bird communities

Samuel Roberts, David Thoma, Dusty Perkins, Elizabeth Tymkiw, Zachary Ladin & Gregory Shriver
Aridland breeding bird communities of the United States are among the most vulnerable to drought, with many species showing significant population declines associated with decreasing precipitation and increasing temperature. Individual breeding bird species have varied responses to drought which suggests complex responses to changes in water availability. Here, we evaluated the influence of water deficit, an integrative metric of drought stress, on breeding bird communities within three distinct aridland habitat types: riparian, pinyon-juniper, and sagebrush...
