On March 6, 1806 Captain Clark described four kinds birds as gulls; technically, 3 are gulls, but his "White Gull" is actually the fulmar. The others were Bonaparte’s gull (named for the naturalist Charles Bonaparte, a nephew of the French emperor), the glaucous-winged gull, and the western gull.
Capt. Clark, March 6, 1806--a White Gull about the size of the second with a remarkable beak; adjoining the head and on the base of the upper chap there is an elivated orning of the same substance with the beak which forms the nostriels at A; it is somewhat in this form the feet are webed and the legs and feet of a yellow color. the form of the wings body &c are much that of the 2d species this bird was seen on Haleys bay. ... (ed. – Capt. Clark is describing 3 different types of gulls and the fulmar) The large Grey Gull is found on the Columbian waters as high as the enterance of the KoosKooske and in common with the other species on the coast; the others appear confined to the tidewater, and the 4th species (ed. the fulmar) not so common as either of the others.
