Abstract
Geographic variation in plumage color of Chamaea fasciata (Wrentit) from northern California and southern Oregon is related to climate. A new subspecies, Chamaea fasciata margra, is described from a disjunct population of southern interior Oregon. Colonization of C. fasciata in interior Oregon was perhaps from birds crossing coniferous forests via isolated balds of Ceonothus. Recent increases of Wrentits in interior Oregon may be in response to habitat alterations (deforestation, fires) and concurrent global warming.
