  • California Rare & Endagered Birds

    California Rare & Endagered Birds

    California brown pelican Pelecanus occidentalis californicus State Endangered 1971 Fully Protected Federal Endangered 1970 General Habitat: The California brown pelican uses a variety of natural and human-created sites, including offshore islands and rocks, sand spits, sand bars, jetties, and piers, for daytime loafing and nocturnal roosting. Preferred nesting sites provide protection from mammalian predators and sufficient elevation to prevent flooding of nests. The pelican builds a nest of sticks on the ground, typically on islands or offshore rocks. Their nesting range extends from West Anacapa Island and Santa Barbara Island in Channel Islands National Park to Islas Los Coronados, immediately south of and offshore from San Diego, and Isla San Martín in Baja California Norte, Mexico. Description: The brown pelican is one of two species of pelican in North America; the other is the white pelican. The California brown pelican is a large, grayish-brown bird with a long, pouched bill. The adult has a white head and dark body, but immature birds are dark with a white belly. The brown pelican weighs up to eight pounds and may have a wingspan of seven feet. Brown pelicans dive from flight to capture surface-schooling marine fishes. Status: The California brown pelican currently nests on West Anacapa Island and Santa Barbara Island in Channel Islands National Park. West Anacapa Island is the largest breeding population of California. In Mexico, the pelicans nest on Islas Los Coronados and Isla San Martín. Historically, the brown pelican colony on Islas Los Coronados was as large as, or larger than, that of recent years on Anacapa Island.

The West Basin supports sensitive vegetation habitats (e.g., pickleweed/cordgrass marsh and eelgrass beds), diverse fish, benthic invertebrate, and avian communities, including threatened and endangered bird species (Belding’s savannah sparrow, California least tern, light-footed clapper rail, Western snowy plover). Water quality potentially could be degraded, and biological resources potentially could be adversely impacted by these increased stormwater discharges into the basin. The analysis focused on the four primary effects of the increased runoff that would be expected to contribute to potential biological impacts within this unique setting: erosion from high velocity discharges; dilution and salinity depression; sedimentation in the West Basin; and increased pollutant load transported by runoff as a result of the project. No adverse impacts to water quality or biological resources would be expected to occur due to the discharge of stormwater runoff into the West Basin of Batiquitos Lagoon under any of the scenarios evaluated (2-, 5-, 10-, 50-, and 100-year storm events).
