Some New Splitsby Betty Burridge The American Ornithologists' Union has recognized several new species of birds that are pertinent to Sonoma County birders: * The Plain Titmouse has been split into two species: the Oak Titmouse, which occurs west of the Sierra Nevada, and the Juniper Titmouse, which is found in Great Basin habitats east of the Sierra Nevada. * Solitary Vireo has been split into three species: Cassin's Vireo, which is "our" western bird; the Blue-headed Vireo in the east; and the Plumbeous Vireo, which is found in the southern Great Basin and Sonoran and Chihuahuan deserts. * The Marbled Murrelet has been divided into Marbled Murrelet and Long-billed Murrelet, which is reported from Humboldt County and several lakes in interior North America. For those who are mystified by these seemingly endless name changes, we'll have an article on "Lumping and Splitting" in an upcoming issue of the Leaves. |
