Coastal lagoons, with their adjacent beaches, salt marshes, and mudflats, are important habitats for numerous birds, including terns and shorebirds. These habitats are used by both migratory and resident species, the former including not only those present during the winter, but also those that reproduce in the area. The future of these habitats is threatened by the ever-increasing impacts of residential and recreational development. In California, two of the bird species that have been most directly affected by the loss or reduction of these habitats are the Snowy Plover (Charadrius alexandrinus nivosus) and the California Least Tern (Sterna antillarum browni). In Baja California, coastal lagoons harbor important breeding populations of these species, but, even here, the colonies are being directly affected by the off-road vehicles and pets of tourists. As indicated by Atwood (1987), their habitat, besides these individual species, should be considered endangered. Accordingly, it is important to inventory the present extent and utilization of these habitats before additional plans to develop them are approved and carried out. We present here a survey of the breeding birds of two such coastal wetlands, Laguna Figueroa and La Pinta Pond, Baja California.
