This is the second edition of the annotated checklist of birds of Glen Canyon National Recreation Area (GLCA), in southern Utah and northern Arizona. The checklist documents every species of bird known to occur within the area with information on abundance, distribution, ecology, dates of occurrence, residency, breeding status and noteworthy records. In all, 341 species have been reported from the National Recreation Area since the first surveys in the region during the 1930's. The checklist reflects all observations and records from the 1930's through 1 July 2021.The published sources of these records may not be referenced in text and are compiled in the literature cited section. Noteworthy and rare observations are credited to the observer when possible. Of the 341 species there are a few observations of species that are considered exotic escapees including Black Swan, Budgerigar and Scaly-breasted Munia. Historical data from pre-Glen Canyon Dam surveys are incorporated, as well as significant monitoring done in the national recreation area since 1992. Breeding is documented for 95 species and an additional 17 probable/possible breeders, including 89 native species and six non-native/exotic species. Many rare species are reported for the first time from Utah, and from Coconino County within Arizona, and several recent range extensions are documented. The species accounts follow the taxonomic order formatted by the American Ornithologists' Union Checklist of North and Middle American Birds, 7th edition (1998), including changes through the 61st supplement (Chesser et al. 2020).
