Humpback whales steal birds' dinner

Humpback whales have come up with a novel way for getting an easy snack - stealing birds' dinners. A BBC crew filmed seabirds carefully corralling unwieldy shoals of herring into tightly packed "bait balls" from which the fish are easy to pluck. But they discovered that passing whales would wait for the birds to complete their hard graft before devouring the ball of fish in a single gulp. The team said this was the first time they had seen this behaviour.
