          Abstract

          We report sightings of the Olrog's Gull (Larus atlanticus) obtained during observations of the interaction between commercial high-seas trawl fisheries and seabirds off Argentina. In late spring 2009, up to eight individuals (both adult and sub-adult birds) were noted feeding on fishery discard of an ice-trawler operating in waters relative close to the El Rincón estuary, southeast Buenos Aires Province. This is the first record of Olrog's Gull exploiting discards from high-seas fisheries 120 nautical miles off the coastline during the breeding season.

          La gaviota cangrejera (Larus atlanticus) asociada a arrastreros de altura durante la temporada reproductiva. En este trabajo se dan a conocer avistajes de la Gaviota Cangrejera (Larus atlanticus) obtenidos durante el desarrollo de un proyecto de evaluación de la interacción entre pesquerías de arrastre de altura y aves marinas en aguas argentinas. A fines de la primavera de 2009, ocho individuos (incluyendo aves adultas y subadultas) fueron registrados alimentándose del descarte pesquero de un buque arrastrero fresquero en aguas cercanas al área del frente costero de El Rincón, en el sudeste de la provincia de Buenos Aires. Este es el primer registro de la Gaviota Cangrejera haciendo uso del descarte proveniente de pesquerías de altura a una distancia de 120 millas náuticas de la línea de costa durante la etapa reproductiva.
