BLACK-BILLED GULL (Chroicocephalus buller)
NAME: The English name ‘Gull’ would have its origins in Old Celtic ‘Gullan’ and other languages, including Latin ‘gula’ for throat. As per Choate this would be related to the gull’s ‘indiscriminate’ scavenging habits, its ‘willingness to swallow almost anything’ (think ‘gullible’).
Black-billed gulls were seen in Christchurch and Kaikoura on the South Island. They are only found in New Zealand and are now listed as ‘endangered’. In terms of size the black-billed gull is a small member of its family. It has a black bill and black legs.
