California Ridgway’s rail (Rallus longirostris obsoletus)  occur almost exclusively in tidal salt and brackish marshes with unrestricted daily tidal flows, adequate invertebrate prey food supply, well developed tidal channel networks, and suitable nesting and escape cover as refugia during extreme high tides. Results of an estuary-wide survey estimated a minimum average population between 2005 and 2008 of 1,425 California Ridgway’s rails (Liu et al. 2009), however, densities declined during that period at a per-year rate of 20 percent and current numbers are likely lower. Reference
