232 NORTH AMERICAN BIRDS. 



Vancouver. It was very common throughout the mountains, and he found it 

 in every portion of the country west of them, even where scarcely a bush 

 was to be seen. 



According to the careful observations of Mr. Eobert Kidgway, this AVar- 

 bler, during the summer months, in the Great Basin, chiefly inhabits the 

 pines of the high mountain ranges, as well as the cedar and pinon woods of 

 the desert mountains. In winter it descends to the lower portions, being 

 then found among the willows, or, in small roving companies, hopping among 

 the tree-tops in the river valleys. In manners it is said by him to resemble 

 the coro7iata, but in their notes they differ very widely. A nest, containing 

 three young, was found by Mr. Eidgway near the extremity of a horizontal 

 branch of a pine-tree, about ten feet from the ground. 



The eggs of the Audubon Warbler do not resemble those of any Douhoica 

 with which I am acquainted, but are most like those of the Hooded AYar- 

 bler. They measure .70 by .50 of an inch, have a ]-eddish or pinkish white 

 ground, and are sparingly marked with fine brown markings, tinted with a 

 crimson shading.

Sr. Char. Male, in spring. Bill dark bluish-black, rather lighter beneath. Tail dusky. 

 Top of head light grayish-blue. Front, lore, cheek, and a stripe under the eye, black, running 

 into a large triangular patch on the back between the wings, which is also black. Eyelids 

 and a stripe from the eye along the head white. Upper tail-coverts black, some of the 

 feathers tipped with grayish. Abdomen and lower tail-coverts white. Rump and under 

 parts, except as described, yellow. Lower throat, breast, and sides streaked with black ; 

 the streaks closer on the lower throat and fore breast. Lesser wing-coverts, and edges of 

 the wing and tail, bluish-gray, the former spotted with black. Quills and tail almost black ; 

 the latter with a square patch of white on the inner webs of all the tail-feathers (but the 

 two inner) beyond the middle of 'the tail. Two white bands across the wings (sometimes 

 coalesced into one) formed by the middle and secondary coverts. Part of the edge of 

 the inner webs of the quills white. Feathers margining the black patch on the back 

 behind and on the sides tinged with greenish. Length, 5 inches; wing, 2.50; tail, 2.25. 

 Autumnal males differ in absence of black of back, front, sides of head, and to a consider- 

 able degree beneath, and in much less white on the wings and head. 



Female in spring. Similar, but all the colors duller. Black of the back restricted to a 

 central triangular patch.

 mala and Panama; Bahamas ; Cuba (very rare).
