heard but those who have say that it is similar to that of the 

 Red-eyed Vireo but uttered more slowly, deeper and in a 

 richer tone and frequently interrupted by harsh scolding notes. 

 In Maine the nesting date would seem to be about the 

 second week in June. A set of eggs in my possession from 

 Connecticut was taken near Wethersfield June 4, 1892. The 

 data states the nest was in the fork of a maple limb, pendant 

 in usual fashion, about fifteen feet from the ground by the side 

 of the main street of the village. This nest is three inches 

 deep externally by one and three quarters internally, the 

 diameter outside two and three-quarters and inside one and a 

 half inches. It is composed of willow cotton, soft plant down 

 and fiber, covered with hornet's nest paper and lichens exter- 

 nally, held together with numerous spider webs, and lined with 

 hair and fine grass. The eggs measure 0.85 x 0.61, 0.86 x 0.58, 

 0.82 x 0.56, 0.86 x 0.56, and are white in color, sparsely spotted 

 with small rounded spots of brown, umber and black, chiefly 

 about the larger end. Three or four eggs are the usual number 

 laid.
