THE BLUE-WINGED YELLOW WARBLER. 417 



River of the north. Some 4.50 long, it is olivaceous above, 

 becoming a delicate ash on the head and neck, the lores being 

 shaded with dusky, and the ring around the eye, and the 

 line over it, being whitish; the under parts are white, some- 

 times slightly tinged with yellow. In the female and young, 

 the ash of the head and neck is more or less olivaceous. It 

 breeds far to the north, its nest having been found at Michi- 

 picoton on Lake Superior. In all stages of plumage it may 

 probably be distinguished from the two former by its wing, 

 w r hich is some 2.75, and therefore from .25 -.50 longer. 



THE BLUE-WINGED YELLOW WARBLER. 



On the 18th of May, in Northeastern Ohio, I took a 

 bird of this genus, the Blue-winged Yellow Warbler 

 (Hclminthophaga pinus) . That seems to be about the north- 

 ernmost limit of this rather southern species. I detected 

 it from its feeble and drowsy song, sounding like the sylla- 

 bles, su'ee-e-c-e-e-zree-e-e-e-e, in a decidedly insect tone, and 

 the latter part in the falling inflection. It is quite suggestive 

 of the song of the Yellow-winged Sparrow. About 5 

 inches long; yellowish-olive or light-green above; forehead 

 and entire lower parts bright yellow; bill and strip through 

 the eyes, black; wings and tail a light slaty-blue, the former 

 with two bars of white, the latter with white blotches in the 

 outer feathers. All the colors are particularly delicate and 

 beautiful. Female and young similar. Though but an 

 humble musician, this bird is very beautiful to the eye. In 

 keeping with the rest of its genus, its nest is on the ground. 

 " The eggs, of the usual shape, and measuring about .63 X 

 .48, are white, sparsely sprinkled, chiefly at the great end, 

 with blackish dots, and few others of lighter dirty-brownish."
