248 THE WARBLING VIREO. 



woody fibers, some dried grass and shreds of bark, inter- 

 mixed with bits of wasp-nest, vegetable down, and the 

 white, fine-spun substance of certain cocoons. It is lined 

 with fine shreds of the grape-vine. Another nest, suspended 

 in the ordinary way, is similarly made up, but very shallow, 

 not more than IJ^ inch in depth outside. 



Though the summer habitat of Vireo gilvus is given as far 

 west as the High Central Plains, I do not think it extends 

 very far north of Lake Ontario. I did not meet with it on 

 Georgian Bay nor in Nova Scotia. Mr. Chamberlain does 

 not report it from New Brunswick, and Mr. Everett Smith 

 regards it as rare in Eastern Maine. It is probably a bird 

 of the Alleghanian Fauna. 



The Brotherly-love^ or Philadelphia Vireo, probably a 

 closely-allied species to the Warbling, is also found occa- 

 sionally in this locality. It is quite a little shorter than the 

 latter, perhaps half an inch, and the colors are brighter — 

 the olivaceous having more of green, and the white having 

 more' of yellow — the breast, for instance, being in some 

 cases quite yellow. When first studying birds, the eye 

 being not yet trained to the exact observance of form and 

 color, I noticed the difference at once on procuring the 

 Philadelphia. Like other Vireos, its nest and eggs are 

 probably in close conformity to the general type. It is not 

 uncommon in New England, nor in New Brunswick, while 

 it is said to be abundant every spring, and quite common 

 on the Red River of the north. 



Mr. Wm. Brewster found this species common about 

 Umbagog Lake in the breeding season. He says: " Con- 

 trary to what might be expected from the apparently close 

 relationship of the two birds, the song of this species does 

 not in the least resemble that of Vireo i^ih-ns. It is, on the 

 other hand, so nearly identical with that of V. olivaceus that
