330 VIRBOS. 



bly common S. R., May 3 to Sept. 18. Cambridge, eommon S. R., May 10 to 

 Sept. 2.5. 



Nest, pensile, of grasses and plant fibers, firmly and smoothly interwoven, 

 lined with fine grasses, suspended from a forked branch eight to forty feet 

 up. Eggs, three to four, white, with a few species or spots of black, umber, 

 or rufous-brown, chiefiy about the larger end, '^G x '55. 



Unlike its cousin, the Preacher, the Warbling Vireo is not gen- 

 erally distributed, but shows a decided preference for rows of shade 

 trees, particularly rows of elms. It passes the greater part of its time 

 in the upper branches, and is more often heard than seen. 



Although resembling the Red-eye in general appearance, its song 

 is so different that singing birds need never be mistaken for that spe- 

 cies. Instead of the Red-eye's broken, rambling recitative, the song 

 of the Warbling Vireo is a firm, rich, continuous warble with a singu- 

 lar alto undertone.

The Yellow-throated Vireo is a dweller in tree tops, and whether 

 in woodland, orchard, or lawn, he seldom comes below the upper story 

 of his home. But even at a distance his bright yellow breast is a con- 

 spicuous mark, at once distinguishing him from other members of his 

 family. 



If the Red-eyed Vireo is a soprano, the Yellow-throat is a con- 

 tralto. He sings much the same tune, but his notes are deeper and 

 richer, while they are uttered more deliberately and with greater ex- 

 pression than those of his somewhat too voluble cousin. " See me ; 

 I'm here; where are you'?" he calls, and at intervals repeats his ques- 

 tion in varying forms. Sometimes he astonishes us by an intricate 

 liquid trill which suggests the wonderful song of the Ruby Kinglet, 

 but which unfortunately is sometimes marred by the scolding notes 

 that precede or follow it.
