Glaucous Gull

 

polar gull (Lurs hyperboreus), a bird of the gull family, of the order of plovers. Plumage is white; spine and wings, light gray; bill, yellow; and feet, yellowish pink. Length, 64-80 cm; weight 1.4-2.1 kg.

The glaucous gull is distributed all around the pole. It nests on the rocky shores of continents and islands. It lays one clutch of two or three eggs a year. Both parents brood for 27 to 28 days. During the nonnesting seasons the gull migrates out to sea. It feeds on sea wastes, fish, carrion, and so forth. The glaucous gull causes large losses to bird nesting grounds by destroying nests.
