RUNNER-UP, ANIMAL BEHAVIOUR
SOUTHERN ROYAL ALBATROSS
A southern royal albatross (Diomedea epomophora), with its wings unfurled, practises ‘sky calling’, while two others clap bills. This behaviour is part of a complex courtship rehearsal performed by groups of up to a dozen young pre-breeding birds who advertise for partners using a complex repertoire of signals known as gaming.
