This annotated checklist of the 36 shorebird species that have been recorded at Ensenada de La Paz, Baja California Sur, Mexico, is based on our field observations carried out over a 12-year period as well as records in the literature. We present new records for species at various geographical scales: Mexico (Terek Sandpiper), Mexican Pacific (Curlew Sandpiper), Baja California Sur (Ruff, Semipalmated Sandpiper and Stilt Sandpiper) and Bahía de La Paz (Solitary Sandpiper and Pectoral Sandpiper). At Ensenada de La Paz, shorebird concentration areas are the mudflats in the southern part of the estuary and two artificial freshwater ponds close to these mudflats. The most important species in terms of both abundance and frequency of occurence are Western Sandpiper, Marbled Godwit and Whimbrel. Breeding in the study area is confirmed for six species: Snowy Plover, Wilson’s Plover, Killdeer, American Oystercatcher, Black-necked Stilt and American Avocet. The study area constitutes one of the most diverse sites for shorebirds in Mexico.
