Site description Chorrera Bay contains extensive mudflats (4,300 ha), extending up to 4 km offshore, from Punta San Juanito north of Chame Bay to the Caimito River estuary 15 km west of Panama City. La Chorrera, Panama’s fourth largest city, is 4 km inland from the northern part of the bay, and there is a small port facility at Puerto Caimito on the Caimito River.

Key Biodiversity Chorrera Bay is an important site for migratory shorebirds, with a maximum one-day count of 9,365 small shorebirds in November 1997. Based on turnover during passage migration, it is estimated that 36,500 Western and Semipalmated Sandpipers may pass through the site.

Non-bird biodiversity: None known.
