About a gull

Ivory gull is a bird that is breeding in vicinity of the high north pack-ice zone. It takes small fish and crustaceans, like other small gull like species, but it is also commonly seen feeding on seal corpses killed by a polar bear. These corpses are probably a significant part of the diet of this weird animal.

As a small species it probably can't compete most decent breeding sites with other seabirds such as kittiwakes. Thus small ivory gull colonies are found from inaccessible places such as nunataks (mountain tops in middle of glaciers, photo below) around the archipelago. Studying these gulls insists cool helicopter flights between mountain tops. Sometimes field assistants get lucky and are asked to join to have fun with the big guys and the flying machine...
