The presence of raptor species may negatively affect the recovery of special status avian species populations in southern Californian salt marshes. This study investigates the environmental and biological factors influencing red-tailed hawk (Buteo jamaicensis), osprey (Pandeon halieatus) and American kestrel (Falco sparverius) perching preferences in order to better inform raptor management within the Los Cerritos Wetlands, Seal Beach National Wildlife Refuge and Bolsa Chica Ecological Reserves. Perching geography and frequency were mapped using GIS and analyzed in relation to adjacent habitats types and perch substrates. Results indicate that anthropogenic perches and certain habitat types, primarily roads and waterways, are vital components to raptor life in humanized salt marshes.
