Bio
John Takekawa established the USGS San Francisco Bay Estuary Field Station in 1995 under the Western Ecological Research Center, co-located with the San Pablo Bay National Wildlife Refuge. His research focuses on the wintering and migratory ecology of waterbirds through radio telemetry, and ecological processes in San Francisco Bay. His studies have focused on projects in the San Francisco Bay estuary, California wetlands, and Pacific Rim countries including Russia, Japan, and Mexico.
