BIRDS OF KANSAS. 525 



about the 20th of May; the bulk leave early in September; a 

 few occasionally linger into October. 



B. 253. R. 140. C. 176. G. 66, 266. U. 628. 



HABITAT. Eastern United States, occasionally crossing the 

 line into the British possessions; south in winter through east- 

 ern Mexico, to Costa Rica. I found them quite common in 

 Guatemala. Breed throughout their United States range. 



SP. CHAR. "Head and neck above and on sides, with interscapular region, 

 bright olive green. Lower back, rump, tail and wing coverts ashy. Wings 

 brown, with two white bands across the coverts, the outer edges of inner sec- 

 ondaries* and inner edges of all the quills, with inside of wing, white. Outer 

 primaries edged with gray, the inner with olive. Tail feathers brown, entirely 

 encircled by a narrow edge of white. Under parts to middle of body, a line 

 from nostrils over eye, eyelids, and patch beneath the eye ( bordered behind by 

 the olive of neck), bright gamboge yellow; rest of under parts white, the flanks 

 faintly glossed with ashy. Lores dusky. No spurious primary evident; second 

 quill longest; first shorter than third. 



"Autumnal birds, perhaps more especially the young, are more glossed with 

 olivaceous, which invades the ashy portions and tinges the white." 



Stretch of 

 Length. wing. Wing. Tail. Tarsus. Bill. 



Male 5.75 9.60 3.10 2.20 .75 .50 



Female... 5.60 9.40 3.00 2.10 .75 .48 



Iris brown; bill end dusky, rest bluish; legs, feet and claws 

 lead color. 



These handsome birds frequent the woods, and seem to prefer 

 the timbered lands along the streams; at least, this is the case 

 in their western range. In the Eastern States they are said to 

 be quite a familiar bird, and to inhabit alike the orchards and 

 shade trees; and, as they are not wild or timid, will no doubt 

 soon become accustomed to the presence of man, and readily 

 make their homes about our prairie dwellings, as soon as the 

 trees and shrubbery form inviting haunts; at any rate, they are 

 much more common here than in former years. 



In flight they are less steady and not so swift as the Red-eyed. 

 Their food habits are the same, but they look more for the 

 supply among the foliage in the treetops. Their song is not 

 so constant, and is delivered in a slower and more plaintive 

 strain, but in a very clear and musical manner. Among the 

 Yireos they rank next to the Warbling in song.
