Studies of breeding biology, movements and dispersal are being undertaken. Localised and nationwide counts are ongoing. Habitat restoration and protection in the MacKenzie Basin is undertaken as part of Project River Recovery, including predator research and a public awareness campaign5. Conservation Actions Proposed
Monitor key breeding populations. Initiate nest protection and trapping of introduced predators at key colonies. Initiate riverbed weed control if nesting habitat continues to be lost. Assess possible impact of further hydro-dam, gravel and water extraction proposals5.
The Black-billed Gull (Chroicocephalus bulleri), also known as Buller's Gull, is a species of gull in the Laridae family. It is found only in New Zealand.
As is the case with many gulls, it has traditionally been placed in the genus Larus, but is now considered to belong within the genus Chroicocephalus. The holotype is in the collection of the Museum of New Zealand Te Papa Tongarewa.
It is a lightly coloured gull with a small amount of black on its wingtips. It has a long, thin, black bill with a bright red interior, and reddish black feet and white eyes. The juvenile has a flesh coloured bill with a dark tip and dark brown eyes.
As juvenile red-billed gulls display similarly dark bills and feet they can be confused.
