Species account number 714 in the Birds of North America Life Histories for the 21st Century
In 1992 the American Ornithologists' Union in partnership with the Academy of Natural Sciences of Philadelphia undertook the publication of species accounts for each of the more than 700 species which breed in the United States and Canada. These illustrated reviews provide comprehensive summaries of the current knowledge of the species, with range maps and an extensive list of references. The series is finally complete, in 716 parts.
