Sp. CHAR. "Male: Upper parts, exclusive of wing and tail, clear yellow 

 olive greeu; the feathers of the back with hidden streaks of black. Forehead

During the breeding season these sylvan birds inhabit the 

 coniferous forests, from my observation preferring the hilly up- 

 lands; and, in migration, are more common in the groves and 

 trees skirting the streams than in the heavily wooded bottom 

 lands. They live almost wholly in the upper branches of the 

 trees, and seldom alight upon the ground, except in search of 

 material for a nest, or at the water's edge to bathe. They feed 

 largely upon leaf worms, spiders, beetles and flies, and in their 

 search for the same are in actions much like the Vireos, hopping 

 about among the boughs and capturing occasionally in the air 

 never in the creeping manner of some of the family. 



In the early part of June, 1880, I found them nesting at 

 Digby, Nova Scotia, in the thick growths of hemlock, spruce 

 and pine. I discovered two nests that the birds were building. 

 They were at least thirty feet from the ground. The males 

 were singing in every direction. Their song is quite loud; a 

 pleasing, reed-like chant, the higher notes too shrill to be 

 musical. Their ordinary call note is a common "Chip," or 

 "Tsip." 



Their nests have occasionally been found near the ground, 

 but such finds are exceptional; as a rule, they range from about 

 fifteen to fifty feet from the ground. They are usually built on
