Offal discards are probably one of the causes of albatrosses congregations in offshore waters of southern Peru

We perform two fishing trips in oceanic areas in southern Peru, between May and July 2021. During the fishing activities, when the fishermen discarded the sharks offal, a particular behavior of the pelagic birds was noticed, there were a lot of fighting and interactions for the offal, the first arriving were the White-chinned Petrels and the South Poar Skuas, then the Black-browed albatross approached but in a shy manner. However, when the shark liver was discarded, the approach of the birds was much more intense and fights were generated, later arrived the Buller albatrosses, generating strong. The shark liver discards also generated the presence of Chatham albatrosses and Northern Giant Petrels who generally beat their other opponents to get the food. This type of offal discards can contribute strongly to the presence of these albatrosses species in oceanic waters of southern Perú.
