To date no general account of the birds of Sinaloa has been published. The subtropics, warm desert, and montane habitats converge in Sinaloa, making the state an area of high bird diversity. Of Sinaloa’s habitats, the coast has been studied the most. This coast includes a series of wetlands known to be important to birds. For example, Bahía Santa María–La Reforma and Ensenada Pabellones, two of the best studied areas, are key stopover and wintering sites for shorebirds (Englis et al. 1994) and waterfowl (Kramer and Migoya 1989). They also sustain important populations of breeding and resident birds (Carmona and Danemann 1994, Howell and Webb 1995, González-Bernal et al. 2003). Yet ornithological research in Sinaloa has been limited, and knowledge of the state’s birds is far from complete. Here we report some noteworthy records that we have made since 1998, mostly in the two bays mentioned above, but also elsewhere along the coast and at a few inland sites.
