| contents | Inventory and conservation of breeding waterbirds at ojo de liebre and guerrero negro lagoons, Baja California Sur México Aradit Castellanos Federico Salinas Alfredo Ortega Rubio Ciencias de la Tierra Ojo de Liebre Baja California Sur breeding waterbirds Surveys made in 1997/98 at the lagoons of Ojo de Liebre (Scammons Lagoon) and Guerrero Negro,Baja California Sur, Mexico, showed that changes have occurred since 1926 in the species compositionof the community of breeding waterbirds, in the arrangement of their nesting substrate and in theirpopulation size. Of 17 species breeding in the area in 1926, we found 12 nesting there during our survey.Additional data from other researchers allowed us to conclude that 16 species have nested in the area after1984. Only one species (Sterna elegans) has not been reported nesting; however, it is still considered tobe a local breeder. Three species (Egretta alba, Larus atricilla and Falco peregrinus) became newestablished breeders. Most of the species that breed on the islands within Scammons Lagoon have astable population or have increased in number. None of the egret species breeding in 1926 in marshesoutside the islands currently nest there. Four species (Sterna antillarum, Charadrius wilsonia,Charadrius alexandrinus and Rallus longirostris) breed on the islands or at other sites in the lagoons andvicinity. Despite development in the region, the natural wetlands and open-water coverage remain almostunchanged. Natural nesting substrates are mostly confined to the islands and are vulnerable to landpredators, wave erosion and direct human disturbance. These factors may have caused the shifting ofnesting spots from one island to another and to other suitable nesting sites on the lagoons, the urbanlandscape, the saltworks and man-made structures. Breeding waterbirds have been granted limitedprotection through reserves and single-species conservation programs.
