Slender-billed Guillemot

Slender-billed Guillemot [now Marbled Murrelet]
Uria townsendii, Audubon [now Brachyramphus marmoratus]
Octavo edition, plate 475

“I have received not less than four specimens of this small Guillemot from Mr. Townsend, who procured them on the north-west coast of America, not very far from the mouth of the Columbia river. The changes of colour in birds of this genus are well known to be considerable; and I have represented two individuals, supposing one to be an adult, and the other a young bird in its first plumage.”
