Site description The Frailes del Sure are two small precipitous rocky islets seven km off the south coast of the Azuero Peninsula near Venado Beach. The larger is about 200 m long. The islets have little vegetation. Sea conditions and the steep cliffs make landing difficult.

Key Biodiversity This is the only known nesting site in Panama for Sooty Tern (3000 pairs), Bridled Tern (50 pairs) and Brown Noddy (50 pairs). The site is estimated to contain more than 1% of the global population of Bridled Tern. The terns may not breed here on an annual basis, since although many were present in February 1956 and some in March 1962, none were seen in February 1957 (Wetmore 1965, Olson 1997). Peregrine Falcon also occurs.

Non-bird biodiversity: None known.
