This report summarizes waterbird and water quality monitoring efforts by the San Francisco Bay Bird
Observatory between September 2024 and May 2025 at 82 ponds within the South Bay Salt Pond
The San Francisco Bay Bird Observatory (SFBBO) is a nonprofit organization dedicated to the conservation of birds and their habitats through science and outreach.
Gull populations can severely limit the productivity of waterbirds. Relocating gull colonies may reduce their effects on nearby breeding waterbirds, but there are few examples of this management strategy.
The California Gull (Larus californicus) population in the South San Francisco Bay has increased from fewer to 200 breeding Gulls in 1982, to a peak of 52,172 in 2012. Specific to this study there were 46,030 breeding Gulls in 2010 and 37,716 breeding Gulls in 2011.
