A Signy Island study from April 1961 to April 1962 described adults as white with pink skin below the eye. There, the birds fed on shore algae and limpets and also foraged near penguin colonies.
Adults observed on Signy Island had pure white plumage and a pink bare patch below the eye. The paper also describes a bare rim around the eye.
At Signy Island, birds took algae and limpets from the intertidal and splash zones. During penguin breeding they also foraged in colonies, obtaining food regurgitated for penguin chicks.
