(Adapted from author's abstract). The breeding bird community in Denali National Park, Alaska, was studied over a three year period (1993-1995). Birds were surveyed from nine off-road routes in spruce forests from 1993-1995 and from four on-road routes in 1994 and 1995. Thirty-nine species were detected during off-road routes, whereas 80 species were detected from on-road routes. The most abundant species were sparrows ( White-crowned sparrow, American tree sparrow, and Savannah sparrow) and warblers (Wilson's warbler and Orange-crowned warbler). The avian community in Denali National Park was similar to other areas in the region, although there were some distinctive differences. The majority of detected individuals (69%) presumably migrate to the tropics: residents accounted for only 9% of individuals detected. Shrublands had the greatest relative abundance of any habitats surveyed, whereas species richness was greatest in tall shrub and spruce forest habitats. These findings generally concur with previous research in the region. Both habitats should be important components in any program that attempts to monitor avian populations in interior Alaska.
