Rodney B. Siegel (Executive Director) Tel: (415) 663 2051

Rodney joined IBP as a research scientist in 1998, after completing his Ph.D. in Ecology at UC Davis. Since then he has directed IBP's Sierra Nevada Bird Observatory and its Avian Inventory Program, often collaborating with government agencies to design and conduct bird surveys and produce scientifically informed conservation and management recommendations.

Rodney's current research interests include the effects of fire and fire management on forest birds, the ecology and conservation of birds dependent on montane meadows in the Sierra Nevada, the ecology and conservation of owls, and the effects of climate change on birds of western montane forests.

Rodney has published scientific papers in numerous peer-reviewed journals, and serves on the Executive Steering Committee of California Partners in Flight. In September 2008 Rodney became Executive Director of IBP.
