Abstract
The central aim of this project is 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 will provide data on year-to-year fluctuations in breeding bird species and densities, and eventually on any longer-term changes in the local avifauna, of both resident and migratory species; the data base will further understanding of population variability, local shifts in distribution and abundance, and potentially form a source for management and conservation decisions.
