Resumen:
We explored the at-sea behavior and marine
habitat use of the Southern Giant Petrel breeding in Patagonia,
Argentina by means of satellite telemetry. Adult
breeders showed a wide distribution over the Patagonian
Shelf, using 74% of its surface. The maximum distance
traveled from the colonies was 683 km, but on average
birds moved no more than 200 km further away from their
colony. Important marine areas were located in the shelf
break, middle shelf and coastal waters. Areas of activity by
sex overlap between 35 and 94%. Females foraged primarily
away from the coast and males mainly on coastal
areas. Both sexes were capable of flying up to 4,000 km
but most of the foraging trips were of less than 200 km.
Our results emphasize the importance of the Patagonian
Shelf as foraging habitat for pelagic seabirds and contribute
to international efforts to identify and protect a network of
marine sites.
