BREEDING BIRDS OF ESTEROS TOBARI AND SAN JOS, SOUTHERN SONORA

Abstract

Although the ornithofauna of Sonora has been studied since at least the 19th century (van Rossem 1945), it is still rather poorly known. This is particularly true for its southern coastal area. Van Rossem and Hachisuka (1937) provided an extensive list of water birds from Estero Tóbari, but found little evidence of local breeding for most species.
