Everything about The Ivory Gull totally explained
The
Ivory Gull Pagophila eburnea is a small
gull, the only species in its genus. It breeds in the high
arctic and has a circumpolar distribution through
Greenland, northernmost
North America, and
Eurasia.
It
migrates only short distances south in autumn, most of the population wintering in northern latitudes at the edge of the pack ice, although some birds reach more temperate areas.
This species is easy to identify. At 43 cm (17 in), it has a different, more
pigeon-like shape than the
Larus gulls, but the adult has completely white plumage, lacking the grey back of other gulls. The thick bill is blue with a yellow tip, and the legs are black. Its cry is a harsh
eeeer. Young birds have a dusky face and variable amounts of black flecking in the wings and tail. The juveniles take two years to attain full adult plumage.
Ivory Gull breeds on Arctic coasts and cliffs, laying one to three olive eggs in a ground nest lined with moss, lichens, or seaweed. It takes
fish and
crustaceans, but is also an opportunist scavenger, often found on
seal or
porpoise corpses. It has been known to follow polar bears and other predators to feed on the remains of their kills.
