Langnæbbet Dværgalk Brachyramphus perdix

Small, chunky seabird of the northwestern Pacific, usually seen at sea, sometimes near land. Breeding adult is chocolate brown with scaled brown-and-white underparts. Wintering adult is gray above and white below with thin white “spectacles” and patchy white splotches on the sides and back. Nonbreeding Spectacled Guillemot perhaps similar but is significantly larger, with much neater black-and-white plumage (and more extensive white on neck), more prominent forehead, and much longer bill.
