We report recoveries of banded Roseate (Sterna dougallii) and Common (S. hirundo) Terns netted at Mangue Seco, Bahia, Brazil (11? 27'S, 37? 21'W). Mangue Seco is the first reported South American location where large numbers of Roseate Terns concentrate December-March, and where members of both the North American and Caribbean populations occur together during these months. A Roseate Tern recovered at Mangue Seco sets an age record of 25.6 years for the species. Recoveries at Mangue Seco of Common Terns banded in the Azores (37? -38?N, 25? -29?W) suggest there is a regular transatlantic movement by Common Terns between the two locations.
