Larus glaucescens
The Glaucous-winged Gull, Larus glaucescens, is a large, white-headed gull residing from the western coast of Alaska to the coast of Washington. It also breeds on the northwest coast of Alaska. During non-breeding seasons they can be found along the coast of California. It is a close relative of the Western Gull and frequently hybridizes with it, resulting in identification problems—particularly in the Puget Sound area. Glaucous-winged Gulls are thought to live about 15 years. One individual, notable because he had only one leg, lived at least 30.[citation needed] The Glaucous-winged Gull is rarely found far from saltwater. It is a large bird and around the same size as a Herring Gull. It measures 50–60 cm (20–24 in) in length and 120–143 cm (47–56 in), with a body mass of 730–1,400 g (1.6–3.1 lb).[2][3] with a white head, neck, breast, and belly, a white tail, and pearly-gray wings and back. The term glaucous describes its colouration. The ends of its wings are white-tipped. Its legs are pink and the beak is yellow with a red subterminal spot. The forehead is somewhat flat. During the winter, the head and nape appears dusky, and the subterminal spot becomes dark. Young birds are brown or gray with black beaks, and take four years to reach full plumage. The Glaucous-winged Gull nests in the summer, and each pair produces two or three chicks which fledge at six weeks. It feeds along the coast, scavenging for dead or weak animals, fish, mussels and scraps. Its cry is a low-pitched "kak-kak-kak" or "wow", or a more high-pitched wailing.

Feeding on dead starfish seems to be a common behavior among Glaucous-winged Gulls. This is the third time I have been able to photograph this behavior, although I have only seen one bird successfully swallow the starfish. The starfish is Ochre Star (Pisaster ochraceus)

Does it really eat starfish?
good series!
Good suggestion Ava. I added this to the food habits mission.
Wonderful spot and photos!
This could definitely go in the Hunter and Animal Eating Behavior mission. What a series!
Amazing series :)
What a series! I think he would be better off to break off one leg at a time!
