Description
The red-legged kittiwake is a very localised subarctic Pacific species. Apart from the distinguishing feature implicit in its name, it is very similar to its better-known relative, the black-legged kittiwake; other differences include the shorter bill, larger eyes, a larger, rounder head, and darker gray wings, and in the juveniles, which barely differ from the adults, lacking the black tail band and "W" across the wings of juvenile black-legged kittiwakes. Juveniles take three years to reach maturity. Adults are long, with an wingspan and a weight of.Like the Pacific race of black-legged kittiwakes, the red-legged kittiwake has a well-developed hind toe. As occasional individual black-legged kittiwakes have reddish legs, any reports of red-legged away from the subarctic Pacific must record all of the other differences, not just the leg color, for acceptance by bird recording authorities.
