Mark Herzog

Biography

Dr. Herzog is a Wildlife Biologist at the Dixon Field Station.  His expertise and interests are in quantitative analysis of ecological data with specific emphasis in avian systems and the estimation of demographic parameters. Dr. Herzog also develops statistical tools and programs used in the analysis of demography and life history.

Before joining USGS, Mark was the co-Director of the Informatics Division at PRBO Conservation Science (now Point Blue), where he led the development of quantitative techniques for the analysis of avian data and helped create the highly successful California Avian Data Center.
