The spectacled guillemot or sooty guillemot (Cepphus carbo) is a seabird in the auk family.

Description

This species is about 38 cm (15 in) with red legs, black bill, and a blackish iris.

The breeding adult spectacled guillemot is distinctive, mostly plumaged dull sooty-black except for conspicuous white "spectacles" on the face

In adult non-breeding plumage, the underparts are white, uniformly tipped very pale grey-brown. Transitional birds are like breeding adults, except the underparts are scaled with white.

Sexes are alike, but juveniles are separable from adults. There are no subspecies.

Range

The spectacled guillemot's range is restricted to the northwestern Pacific Ocean: throughout the Sea of Okhotsk and the Kuril Islands in Russia and on the northern island of Hokkaidō in Japan. Its range overlaps with that of the closely related pigeon guillemot, though it extends further north.[2]

gollark: > you could get the best damn doctor in the world, highest grades and shit, but you hire him and he doesnt treat minorities, what are you gonna do? He is the best qualified, after allThat would make them... not a good doctor?

gollark: > Well, it ends up being biased, just like life.Don't deliberately include *more*.

gollark: So come up with better scoring criteria, don't just bias the whole system.

gollark: Also, essays are the enemy of mankind and must be destroyed.
