TarāpukaBlack-billed Gull

Conservation status
In serious trouble

The black-billed gull is the most endangered gull in the world. Although it is usually thought of as a seagull, this gull is found on major rivers (especially braided rivers), lakes, and farmland in the breeding season and generally prefers estuaries and coastal areas outside of the breeding season. You are less likely to see them in urban areas than other gulls as they are not big on scavenging for leftovers.
