Presentation Title: Stream-side survival of Rocky Mountain songbirds: Effects of vegetation structure on bird species diversity

The diversity of avian species and their coexistence in riparian habitat has become increasingly significant in the face of rapidly decreasing vegetation along hydric areas, primarily due to urbanization, overgrazing, and climate change. The complex and rare riparian habitat system is primarily supported by willow vegetation in the high-altitude areas of the Rocky Mountains, which provide a multitude of niche types for many species of songbird. The objective of this study was to evaluate songbird community response to differences in vegetative structure. Bird abundance and vegetative composition in riparian habitat was sampled along the East River in Colorado. Overall species richness and diversity was found to increase with higher vegetative complexity, while species abundance was significantly lower at sites with more complex vegetation. The results of this study indicate the importance of understanding the structural requirements of stream-side songbird habitat to effectively manage and improve this threatened ecosystem.
