This species occurs locally throughout the State in migra- 

 tion, arriving about April twenty-fourth to the first of May 

 and departing about October tenth, though given by Mr. 

 Brown as occasional until the middle of November. It is 

 practically a summer resident in every county of the State, 

 though very rare in the southern sections as such, and extremely 

 local even in the regions where when found it may be called 

 even quite common. The species is the earliest to arrive of 

 our Vireos and nests earlier, often having eggs at about the 

 date the other species are arriving. 



The nests are pendant from the forked limbs of trees, 

 usually hemlock, spruce, fir and hackmatack being the trees 

 preferred to build in, though rarely hard wood trees are 

 selected. Such nests as I have seen were placed more fre- 

 quently in hemlock and fir trees in the forks of the lower 

 spreading branches at four to not over ten feet from the 

 ground. Birch, cedar and hemlock bark in fine strips were 

 used to build the nest proper which was covered exteriorly 

 with moss, birch bark, hornet's paper and lichens, held on by 

 spiders' silk, and lined internally with pine needles and grass 

 culms. 



Such nests as I have found about the middle of June con- 

 tained young, so it is evident that the full complement of eggs 

 must have been laid by the very last of May, and as three to 

 four is the number of young, the usual number of eggs must 

 be the same. The nests seemed very similar in size to those 

 of the Red-eyed Vireo, but there is a characteristic appearance, 

 perhaps owing to the material used and the sites selected, which
