Abstract: We present the results of surveys on seabirds from the Tamoios Ecological Station, a marine protected area on the coast of the state of Rio de Janeiro, south-east Brazil. Four line transects counts were carried out aboard small boats in 28 April 2009 (autumn), 22 September (winter) and 15 December 2010 (spring) and 2 February 2011 (summer). The following seabirds were recorded in the region: Brown Booby Sula leucogaster, Magnificent Frigatebird Fregata magnificens, Neotropic Cormorant Phalacrocorax brasilianus, Kelp Gull Larus dominicanus, South American Tern Sterna hirundinacea, unidentified terns (Sternidae), and Cabot's Tern Thalasseus acuflavidus. Magnificent Frigatebirds and the unidentified terns (Sternidae) were the most abundant birds, while Magnificent Frigatebird and Brown Bobby were the most frequent, occurring respectively in 82,25% and 62,5% of all counts. The higher abundance of birds was recorded during the winter counts. Active nests and chicks of Kelp Gulls Larus dominicanus were observed on a rocky islet (Rochedo de São Pedro) in the study areas during the winter counts. Breeding of Magnificent Frigatebirds was in the winter-spring counts on another rocky islet (Laje Branca). No direct evidence of breeding of terns were recorded in the study area, but the observation of birds with breeding plumage in the winter and spring counts suggests breeding may occur within Tamoios Ecological Station.
