ZOOLOGY. 
Nuttall,) horn color , darker at the tip. Lining membrane of the mouth, yellow orange; feet and 
legs, hlach; iris, hazel. Tail extends about 1J inches beyond the folded wings.” This skin 
was unfortunately lost in my missing collection of July and August, 1856. 
This bird is not abundant on Puget Sound, and it is but seldom that a specimen can be 
obtained. But this is partly owing to the preference it has for shady thickets and dense 
foliage, where it is with difficulty shot.—S.

The little pewee of Nuttall is one of the few birds that frequent the dark and gloomy spruce 
forests, which it seems to prefer to more open places. It is most abundant near the coast, but 
I have seen a few at Puget Sound, where they arrived about the 25th of April. It is difficult 
to get a sight of this small musician as it flits through the upper branches of the tall spruces, 
uttering constantly its monotonous but lively ditty. Its colors make it almost invisible in the 
shade. 
It is also a common species about Puget Sound in summer. I could not discover its nest. 
I observed that one of them kept constantly on the border of a small pond, and drove the 
kingbird away from the place. It has a peculiar short and lisping song of three notes in 
summer, very different from other species. In fall the young birds make a very different loud 
call as they wander about the woods. 
I did not find the nest of this bird. By the first of September they have all retired southward. 
Note.— The difference in color of lower mandible observed in this and some other western 
birds may be of value as a specific distinction in connexion with other points stated by Prof. 
Baird.—C. 
Quite abundant in the vicinity of Fort Steilacoom, where it arrives early in May. It seems 
to prefer the vicinity of bushes and low trees at the edges of dense forests. In 1856 I obtained 
at Fort Steilacoom the following: No. 396. May 19. 6£, 9.—No. 421. June 3. 6, 8f.— 
No. 443. June 18. 6^, 8|. 
I found this bird rather less pugnacious than others of the group, and in habits generally 
more resembling the Yireo family. Its notes are short but sweet, and just after sundown on 
warm summer evenings particularly low, plaintive, and soothing.—S.
