Steller's crow. Pennant, Arctic Zool. II, Sp. 139. — Lath. Syn. I, 387. 



Sp. Ch. — Crest about one-third longer than the bill. Fifth quill longest ; second about equal to the secondary quills. Tail 

 graduated ; lateral feathers about .70 of an inch shortest. Head and neck all round, and fore part of breast, dark brownish 

 black. Back and lesser wing coverts, blackish brown, the scapulars glossed with blue. Under parts, rump, tail coverts, and wing, 

 greenish blue ; exposed surfaces of lesser quills dark indigo blue ; tertials and ends of tail feathers rather obsoletely banded 

 with black. Feathers of the forehead streaked with greenish blue. Length, about 13 inches ; wing, 5.85 ; tail, 5.85 ; tarsus, 

 1.75, (1921). 



Hab. — Pacific coast of North America ; east to St. Mary's Mission, Rocky mountains. 



In many specimens there is an appearance of greyish on the chin, owing to the exposed bases 

 of the feathers. There is a faint gloss of bluish gray on the blackish or dark brown of 

 the back, but it is scarcely appreciable. The shafts of the quills and tail feathers are black. 

 The upper surfaces of the tail feathers are blue, not so dark as the secondaries and tertials ; the 

 inferior surfaces brownish black. Bill and feet black. The wings reach about to the end of the 

 upper tail coverts. 



There is some difference in specimens as to the shade of blue, which sometimes has much less 

 of green in it than as described. The black bands on the wings and tail also vary in extent and 

 intensity. The sexes do not differ appreciably in color. 



The specimens in the collection before me are all from the regions of the Pacific towards the 

 coast, except one procured at the Catholic Mission of St. Mary's, among the Flatheads. This, 

 however, is on the western .slope of the mountains. The bird figured by Richardson appears to
