Seasonal distribution of aquatic birds in Estero De San Jose Del Cabo, B.C.S., Mexico

Abstract

In order to determine the seasonal distribution and the importance of each of the species of aquatic and semiaquatic birds in the Estero de San José del Cabo, B.C.S. (Mexico), monthly censuses were performed from September 1986 to September 1987. A total of 12,490 birds, belonging to 50 species, were recorded. The presence and abundance of birds, compared to those reported by other authors, are significantly reduced, probably due to the deterioration of this habitat. In this bird community, the American coot (Fulica americana) was, by far, the most abundant species (9,176 individuals). This lagoon is an important stop for migratory birds, mainly anatids.
