Population Densities and Community Structure of Birds in Jackson Hole: A Reassessment after 25 Years

Abstract

The award covers research expenses for a comparison of bird community structure--species, diversities, densities and distribution, and interspecific interactions--in two habitat types in Jackson Hole/Grand Teton-National Park, 1966-68 data versus 1991-92 data. In 1991 two study sites were re-established in the park, in sites as nearly overlapping as possible sites worked previously in 1966-68. The sites are a) willow scrub habitat, ca. 100 m west of Moran Junction; b) grass-sagebrush/forb meadow, ca. 200 m SE of Moran Junction.
