 dusky line over eye; back, tail and wings, gray olive 

 green, the wings with darker edges; breast, belly and

The nest is the same as that of the Blue-headed Vireo. 

 The eggs are three or four in number, white, with black 

 and brown spots, principally near the large end, and 

 four-fifths by three-fifths of an inch in size. 



The birds breed from eastern North America to Hud- 

 son's Bay and spend the winter in eastern Mexico. 



Their song is a pleasant warble from a tree top, occas- 

 ionally marred by a few scolding notes. Wilson Flagg 

 compares the song to brig-a-dier, brig-a-dier, brig-a-dier, 

 brig ate.

 with grayish tinge; wings, olive green with grayish tinge, 

 yellowish white tips forming double wing bar; feet, dark 

 lead. 



The nest is similar in construction to that of the Blue- 

 headed Vireo, but is built near the ground, generally in a 

 bush, and contains a good deal of green moss in its make- 

 up. The eggs are either three or four in number, white, 

 with black and brown specks more plentiful near the large 

 end, and three-fourths by one-half an inch in size. 



The birds breed throughout the eastern United States 

 and spend the winter in eastern Mexico and southward. 

 They are to be found during the summer all over New
