Utah Birds: Geographic Distribution and Systematics

This is a brand new copy, original stock from the printer. Occasional Publication Number 5, Utah Museum of Natural History. Correlated with its diverse physiography and climate as well as its geographic position, Utah is a meeting ground for three avifaunas. This paper constitutes a terminal report on the geographic distribution and systematic aspects of the birds of Utah. The greater portion of this paper is devoted to systematic reviews of geographically-variable species that have multiple races in the state or to discussions of other species that present systematic problems.
