4/17/20 (P:\TER2001\BA\Special‐Status Species Biological Resources Habitat Assessment 4‐17‐20 .docx) 4 Species Status (Federal/State) Habitat Potential for Occurrencea California brown pelican Pelecanus occidentalis californicus Delisted/ Delisted, SFP Open marine waters with abundant small schooling fish populations, nests on islands lacking terrestrial predators, roosts on isolated islands, rocks, breakwaters, and docks. Could forage in open water habitat within the project site; does not breed in Alameda County, but post breeding adults and young birds disperse north from the Channel Islands in southern California (the closest breeding area) and are most abundant in the County from July through late October. However, within the project area, there may be small numbers of non‐breeding individuals present all year. Species observed at the Oakland International Airport and Oyster Bay (eBird 2020). Western snowy plover Charadrius alexandrines nivosus FT/SSC Sandy beaches, salt pond levees and shores of large alkali lakes. Need sandy, gravelly or friable soils for nesting. No suitable breeding habitat present along the tidal slough. Not likely to nest in the basin due to limited suitable habitat and long period in which the basin is inundated with water. Could briefly fly through or forage at the project site. Closest breeding occurrence is a 1979 record approximately 0.3 mile from the site at Bay Farm Island (CDFW 2020). Species observed at the Oyster Bay Regional Shoreline in January 1984 (eBird 2020). Species has been recorded at the Oakland International Airport (Bloom, pers. comm.). California least tern Sterna antillarum browni FE/SE, SFP Coastal waters, sandy beaches, alkali flats, and hard‐pan surfaces (salt ponds). No suitable breeding habitat present. Could briefly fly through or forage over the open water in the slough. Closest CNDDB occurrence is approximately 2.5 miles from the site at the Oakland Airport. Species observed at the Oakland International Airport, Oyster Bay, and Oyster Bay Regional Shoreline (eBird 2020). White‐tailed kite Elanus leucurus –/SFP Nests in shrubs and trees in open areas and forages in adjacent grasslands and agricultural land. Suitable nesting habitat present in the trees on and adjacent to the site. Species observed at project site during LSA’s field survey. No CNDDB occurrences within 5 miles of the project site. Northern harrier Circus hudsonius –/SSC Nests on the ground among tall vegetation in grasslands, grain fields, sagebrush flats, and emergent wetlands along rivers or lakes. No suitable nesting habitat present. Could forage over or adjacent to the project site. Species observed at the Davis Street dump, Oakland International Airport, and Oyster Bay Regional Shoreline (eBird 2020). American peregrine falcon Falco peregrinus anatum Delisted/ Delisted/ SFP Forages in open country, mountains and sea coasts. Nests on high cliffs, bridges, and buildings. No suitable nesting habitat present; could briefly fly over or forage at the site. Species observed at the Oyster Bay Regional Shoreline (eBird 2020). California black rail Laterallus jamaicensis coturniculus –/ST, SFP Salt marshes bordering larger bays, also found in brackish and freshwater marshes. No suitable habitat present. Closest CNDDB occurrence is a 1995 record at Arrowhead Marsh, approximately 1.9 miles from the project site.
