Abstract

Between 1993 and 1995, the construction of two housing units were built nearby "El Conchalito" beach, Ensenada de La Paz, Baja California Sur. Abundance and richness of shorebirds were censured from February, 1993 to Juanary, 1994 and from February, 1995 to January, 1996, and compared with test of proportions (?=0.05). The results showed that the reductions in abundance and richness were significant. Species abundances were compared using the monthly average percentual difference, using a proportions test. Those species wich presented significant reductions (Limosa fedoa, Catoptrophorus semipalmatus, Limnodromus spp. and Charadrius wilsona) were the most abundant in the beach, while those which had no significant differences were those that were scarce (Calidris mauri and Nemenius americanus). It is problable that population reduction are related with the disturbance caused by the building of a housing facility.
