Abstract: Information is presented which updates current seabird breeding colony locations in the Lesser Antilles. No evidence of breeding was found for Black-capped Petrels (Pterodroma hasitata) in Dominica. Audubon’s Shearwater (Puffinus lherminieri) was found nesting on the St. Martin islet of Tintamarre. Incubating Redbilled Tropicbirds (Phaethon aethereus) were recorded in Anguilla and St. Martin. White-tailed Tropicbird (Phaethon lepturus) nesting was confirmed in St. Martin. An important and possibly recently established Caribbean Brown Pelican (Pelecanus occidentalis occidentalis) breeding colony in St. Martin is described. Our investigations have resulted in significant findings regarding Caribbean seabird conservation. More surveys, however, are necessary in the region to identify seabird breeding locations and evaluate the sustainability of known populations.

Resumen: Informe corriente sobre colonias de crianza de aves marinas en las Antillas Menores-Se presenta información que actualiza las ubicaciones de las colonias de crianza. No se encontro ninguna evidencia de crianza de Pterodroma hasitata en Dominica. Se encontro que Puffinus lherminieri tiene nidos en un cayo de St. Martin. La incubacion de Phaethon aethereus fue documentada en Anguilla y St.Martin. Se confirmo que Phaetheon lepturus tiene nidos en St. Martin. Descripción de una colonía de tamano significante de Pelecanus occidentalis. Estas investigaciones dieron resultados significantes sobre la conservación de las aves marinas del Caribe. Sin embargo, mas estudios de la region son nesesarios para identificar los sitios de los criaderos de las aves marinas y para evaluar el mantenimiento de las poblaciones conocidas.
