ZOOLOGY. 
The summer yellow bird is abundant in this Territory, having the same habits and song as 
in the eastern States. I noticed their arrival in large numbers at the Straits of De Fuca as 
early as April 8. Its nest is built in a bush but a few feet from the ground, formed of fibres 
of roots, bark, &c., and the eggs, about five in number, are white, sprinkled with spots near 
the larger end.—C. 
This bird is abundant among the scrub oaks, thickets, and bushes on the Nisqually plains. 
The late moult commences early in August. May 3, 1856, Fort Steilacoom, Washington 
Territory. Specimen 359. Bill, grayish blue; legs, pale.—S.

Sp. Ch. —Forehead, line over and around the eye, and under parts generally bright yellow. Upper part, olive green; a 
square patch on the crown lustrous black. Sides of body and cheek tinged with olive. No white on wings or tail. Female 
similar; the black of the crown obscured by olive green. 
Length, 4.75 to 6; extent, 5.25 to 8-75?; wing, 2.25; tail, 2.30. 
Hab. —United States from Atlantic to Pacific; south to Guatemala. 
This bird is very abundant in the neighborhood of Fort Steilacoom, frequenting thickets and 
small scrub oak groves. In habits it much resembles the Helminthophaga celata, flitting about 
among the dense foliage of bushes and low trees in a busy, restless manner, like the ‘ ‘ little 
joker,” “now you see him, now you dont.” Its cry is a short chit-chat call.—S. 
I have seen two or three times on the coast a yellow warbler with a black crown, which was 
probably Wilson’s flycatcher, found by Nuttall in Oregon. I only noticed them in spring and 
fall.—C.
