Abstract

This report covers year 2 of a three year project, 1995-1997 inclusive, to instigate a permanent program of monitoring landbird species composition and densities in a variety of representative habitats within Grand Teton National Park (GTNP). Habitats range from grassland and sagebrush on the valley floor of Jackson Hole (around 1900 m) through a range of scrub, woodland, and tall foothill forest vegetation types to montane sites of subalpine fir and tundra (ca. 3000 m). The monitoring program is intended to provide data on year-to-year fluctuations in breeding bird species and densities, and document longer-term changes (if any) in the local avifauna of resident and migratory species. The data base will document variability in size of breeding populations among years, local shifts in distribution and abundance over habitat types, and potentially form an information source on which management and conservation decisions might be based.
