Mangue Seco is the first reported South American location where large numbers of Roseate Terns concentrate December-March, and where member s of both the North American and Caribbean populations occur together durin g 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 ba nded in the Azores (37 degrees-38 degrees N, 25 degrees-29 degrees W) sugge st there is a regular transatlantic movement by Common Terns between the tw o locations.
