From ‘Albatross Cam’ New Insights into Foraging Behavior

By attaching small digital cameras to the backs of several albatrosses in the sub-Antarctic, Japanese and British scientists have discovered that the great seabirds sometimes feed in conjunction with pods of killer whales, apparently picking up scraps left by the predatory mammals. The researchers affixed the cameras to four black-browed albatrosses captured on Bird Island in South Georgia in January, then retrieved three of the four cameras when the seabirds returned to their breeding colonies. The scientists collected nearly 29,000 digital images, some of which showed albatrosses flying behind killer whales and landing in the sea near the orcas. Reporting in the journal PLoS ONE, the scientists said that the albatrosses appeared to be feeding on scraps of Patagonian toothfish or other prey devoured by the killer whales. Such interactions between albatrosses and killer whales have rarely been observed, and the researchers said that one way albatrosses may locate prey in a vast, featureless sea is by spotting orcas and feeding in their vicinity. The cameras, each weighing 82 grams, captured other images of fellow albatrosses in flight, as well as icebergs adrift in the Southern Ocean.
