My current interests focus on abundance and productivity of forest birds in different habitat types, monitoring avian populations, habitat relationships and nest site selection, and dynamics of snag abundance and snag turnover over elevation. In current studies, I examine annual variability in nest success in diverse Sierra Nevada habitats, identify source and sink habitats, and examine elevational shifts in abundance, especially as they relate to weather conditions. This study is part of the King's River Ecosystem Management Research Program (western Sierra Nevada), designed to test two landscape-level, adaptive management alternatives: uneven-aged small group selection and a three-tiered landscape approach. Ongoing, continuing research includes implementation of landbird monitoring techniques, long-term trends of landbirds, and the effects of the invasion of exotic bird species on native cavity-nesting birds.
