Seabirds around fishing vessels

Red-billed gull

Larus novaehollandiae scopulinus

The red-billed gull is widely distributed along the New Zealand coast. The red-billed gulls in this region are considered a subspecies of Larus novaehollandiae which is distributed from New Caledonia to Australia. Because they are coastal, these gulls are rarely recorded during bird counts conducted from fishing vessels.
