The coast of the southern Vizcaino Desert, Baja California Sur, includes three lagoons: La Bocana, El Coyote, and San Ignacio (Figure 1). The avifauna of La Bocana and San Ignacio lagoons was first described by Huey (1927). Since then, the only ornithological research in the area has been by Reitherman and Storrer (1981), Danemann (1991), and Danemann and Guzmán (1992), who studied various aspects of the avifauna of San Ignacio Lagoon. No ornithological information from La Bocana or El Coyote has been published since Huey’s early account.
In September 1991 we surveyed El Coyote and La Bocana lagoons, usually referred as “esteros.” Here we summarize observations recorded during those surveys.
