N. Am., N. to Hudson's Bay and Great Slave Lake, W. to „, , , „ 



' ■' , . „ . . Fig. 168. — Black-and-yellow 



the Eocky Mts. of Colorado ; abundant, chiefly migratory m waibler, nat. size. (Ad nat. del. 



the U.S.; winters extralimital ; breeds from New England E.G.) 



northward. Builds a small neat nest in low conifers; eggs 4-5, O.Gl X 0.48, not peculiar. 



136. D. tigri'na. (Lat. %)■«««, striped like a tiger, tigris.) Cape May Warblek. Adult $, 

 in spring : Back yellowish-olive, spotted with black ; crown in high plumage perfectly black, 

 usually interrupted with olive. Eump, sides of the neck nearly meeting across the nape, sides 

 of head and entire under parts bright yellow ; ear-patch orange-irown ; a black transocular 

 stripe, cutting off a yellow supercihary stripe ; lower throat and whole breast and sides thickly 

 streaked with black ; yellow of throat sometimes tinged with orange-brown ; that of belly and 

 under tail-coverts pale or whitish. Wing-bars fused in a large white patch, faiiaed by middle 

 coverts and outer webs of most of the greater coverts. QuUls and tail-feathers WjK'kish, edged 

 on outer webs with olive; tail-spots on three outer feathers near their ends, oblique, large on 

 outer feather, diminishing on the next successively ; bill and feet blackish. The yellow patch 

 on the rump is conspicuous, and in high plumage that on the side of the neck is immaculate

 paler and less streaked, tail-spots small or obscure; less white on the wing. Young : An in- 

 significant-lpoking bird, resembhng an overgrown ruby-crowned kinglet, without its crest ;

 lowish. Length 5.00-5.25 ; wing 2.75 ; tail 2.25. Eastern N. Am. to Hudson's Bay, only 

 known W. to the Mississippi. Another exquisite, resembling the Magnolia in its yellow rump 

 and yellow black-striped under parts, but easily recognized at maturity by the orange-brown 

 ear-coverts ; possessing also the charm of rarity in most parts. It is also remarkable for the 

 curved and very acute bill, and some anatomical peculiarities of the tongue, which have caused 

 it to be made type of a genus Perissoglossa. Breeds in portions of New England and north- 

 ward ; nest low in trees ; eggs not peculiar.

 its upper arm running through eye, its lower arm connecting with a series of black streaks 

 along the whole sides of the neck and body ; tail-blotches very large, occupying most of the 

 inner web of the outer feathers. The sexes are almost exactly alike, and the young only differ 

 in not being so bright and in having the dorsal patch and head-markings obscure. Small : 

 Length 4.75; extent 7.00-7.40; wing 2.15-2.25; tail 2.00. Eastern U. S. to Massachu-
