ALT Image containing graphics of albatrosses and fishing vessels and summary of the paper: 1. Bycatch in fisheries is a major threat to seabirds. 2. Can biologging data alone predict if wandering albatrosses are foraging behind vessels? 3. Bird and vessel locations were matched using radar loggers and Global Fishing Watch data. 4. Water landings indicated by wet-dry immersion sensor. 5. Immersion data improved behaviour classification but biologging data were not enough to distinguish natural foraging behaviour from foraging behind vessels. 6. Take home message: Understanding fine-scale interactions between wandering albatrosses and fisheries requires independent data on vessel movements. Correspondence [email protected]
