avifauna, Arizona, Utah, Glen Canyon National Recreation Area, Lake Powell, Glen Canyon Dam
The birds of Glen Canyon National Recreation Area, in southern Utah and northern Arizona, are documented, with information on abundance, distribution, ecology, residency status, and breeding status. In all, 316 species have been reported from the park since the first surveys in the region during the 1930s. Historical survey data from the pre-Glen Canyon Dam surveys are incorporated, as well as significant work done in the park since 1992. Breeding is documented for 87 species, including 82 native species and 5 exotic species. Many rare species are reported for the first time from this section of the state, and several recent range extensions are documented.
