can dive to much greater depths and for much longer than previously thought — three times the maxima previously recorded for this species , and more than twice the maxima reliably recorded previously for any albatross. are the iconic aerial wanderers of the oceans, supremely adapted for long-distance dynamic soaring flight,” said University of Oxford’s Professor Tim Guilford and his colleagues.
“Modern biologging studies have largely confirmed this view, casting doubt on earlier observations using capillary tube maximum depth gauges, which may exaggerate depths, and emphasizing albatrosses’ reliance on near-surface feeding.” Using miniature electronic depth loggers, the researchers documented the journeys of the black-browed albatross population in the Falklands commuting to the South American coast and diving at unexpected depths to pursue prey.
“That black-browed albatrosses are physically capable of such deep dives will now need to be considered when thinking about the effectiveness of mitigation strategies that rely on the species being restricted to the surface.”
