Red-legged Kittiwake: Day 185


This is a red-legged kittiwake (Rissa brevirostris), brevi meaning short, and rostris meaning nose, or in this case a bill. Aside from the bright red legs, a shorter bill is one way to tell these birds apart from a more ubiquitous species the black-legged kittiwake. Breeding only on a few select islands in the Bering Sea, roughly 80% of the world's population of red-legged kittiwakes nest here on the Pribilof's, mostly on St. George just south of St. Paul. Currently they are working on building precarious nest platforms constructed of mud and grass, perched atop slight rock ledges on the sides of steep vertical cliff faces.
