Abstract: Objectives Compare bird community structure (species diversity, density and distribution) within two habitat sites in Grand Teton National Park. Determine if any changes have occurred since this study was performed in 1966-68. Findings and Status Though the basic structures of both habitat types have not changed in 25 years, some differences in species composition have been identified. In grass-sage habitat an overall reduction in emberizidae species was identified. However, starlings and chipping sparrows were identified in 1991 but not 25 years ago.

| ABSTRACT | Objectives
Compare bird community structure (species diversity, density and distribution) within two habitat sites in Grand Teton National Park. Determine if any changes have occurred since this study was performed in 1966-68.
Findings and Status
Though the basic structures of both habitat types have not changed in 25 years, some differences in species composition have been identified. In grass-sage habitat an overall reduction in emberizidae species was identified. However, starlings and chipping sparrows were identified in 1991 but not 25 years ago. |
