Movements and diving behaviour of white-chinned petrels: Diurnal variation and implications for bycatch mitigation ...
Abstract Many seabirds dive to forage, and the ability to use this hunting technique varies according to such factors as morphology, physiology, prey availability, and ambient light levels. Proficient divers are more able to seize sinking baits deployed by longline fishing vessels and may return the...
