This report contains recent decisions of the California Bird Records Committee (CBRC). It officially adds the following species to the state list of California: Greater Shearwater (Puffinus gravis), Cook’s Petrel (Pterodroma cookii), Stejneger’s Petrel (Pterodroma longirostris), Band-rumped (Harcourt’s) Storm-Petrel (Oceanodroma castro), Red-tailed Tropicbird (Phaethon rubricauda), Mongolian Plover (Charadrius mongolus), Sandwich Tern (Sterna sandvicensis), Crested Auklet (Aethia cristatella), Yellow-bellied Flycatcher (Empidonax flaviventris), Sedge (Short-billed Marsh) Wren (Cistothorus platensis), Dusky Warbler (Phylloscopus fuscatus), and White-winged Crossbill (Loxia leucoptera). These bring the state list to 539 species.
Jones et al. (West. Birds 12:57–82, 1981) updated the state list; this Records Committee report was prepared earlier and differs from their list in a few instances.
