Skuas often collaborate to tear up large prey, as ornithologist Edgar Stead observed:
‘A trio which used to feed on the cleared ground in front of our hut on Solomon Island [near Stewart Island], partitioned their prey in the most polite manner imaginable. Number one would take the bird, say a dove petrel, in its bill, getting a good firm grip, then hold it towards number two, who would pull off and swallow its head. Number three would then pull off a wing, and then perhaps number two would hold it while number one had a mouthful.’
