COOL FACTS TOP
Some species of gulls nest in open locations where it can get hot during the day. To keep their eggs or young cool, parents sometimes stand over the nest creating shade on the nest. Other gulls may get their breast feathers wet and then use their wet feathers to cool the eggs.

COOL FACTS about Family Laridae TOP

Skuas and jaegers are more quiet than gulls. They often feed by stealing food from other birds, especially gulls and terns. During the breeding season, Parasitic Jaegers get almost all of their food by "kleptoparasitism" (stealing), eating stolen fish as well as young and eggs of other birds. Four of the seven species of skuas and jaegers have more than one color morph.
