RELATIVE ABUNDANCE, MIGRATION STRATEGY, AND HABITAT USE OF BIRDS BREEDING IN DENALI-NATIONAL-PARK, ALASKA

The breeding bird community in Denali National Park, Alaska, was studi ed 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-roa d routes in 1994 and 1995. Thirty-nine species were detected during of f-road routes, whereas 80 species were detected from on-road routes. T he most abundant species were sparrows (White-crowned Sparrow [Zonotri chia leucophrys], American Tree Sparrow [Spizella arborea], and Savann ah Sparrow [Passerculus sandwichensis]) and warblers (Wilson's Warbler [Wilsonia pusilla] and Orange-crowned Warbler [Vermivora celata]). Th e avian community in Denali National Park was similar to other areas i n the region, although there were some distinctive differences. The ma jority of detected individuals (69%) presumably migrate to the tropics ; residents accounted for only 9% of the individuals detected. Shrubla nds had the greatest relative abundance of any habitats surveyed, wher eas species richness was greatest in tall shrub and spruce forest habi tats. These findings generally concur with previous research in the re gion. Both habitats should be important components in any program that attempts to monitor avian populations in interior Alaska.
