Integrating immersion withGPSdata improves behavioural classification for wandering albatrosses and shows scavenging behind fishing vessels mirrors natural foraging

Abstract: Advances in biologging techniques and the availability of high‐resolution fisheries data have improved our ability to understand the interactions between seabirds and fisheries and to evaluate mortality risk due to bycatch. However, it remains unclear whether movement patterns and behaviour differ between birds foraging naturally or scavenging behind vessels and whether this could be diagnostic of fisheries interactions. We deployed novel loggers that record the GPS position of birds at sea and scan the surrou… Show more

“…In our study, dives only lasted 1.4 ± 0.6 s seconds and were infrequent and dispersed (just 1.2 ± 1.3 dives per GPS position, and only 22% of dives were recorded within the same or in adjacent GPS positions), suggesting that foraging may be obscured by resting and travelling if dive-specific auxiliary data is not available. Similar observations have been made in the attempt to distinguish mating behaviour in GPS-tracked deer [ 53 ] or in the differentiation of natural and non-natural foraging in seabirds [ 3 ]. In these cases, the addition of more complexe auxiliary sensors (such as cameras, TDRs, and accelerometers etc.)…”

“…may be needed to truly identify these particular behaviours. Auxiliary devices have been used in combination with GPS data to identify foraging behaviours in many seabirds and seals, which may otherwise be impossible [ 3 , 32 , 54 , 55 ].…”
