FAMILY Vlnoaldx. 



The structure of his song is not unlike that of the 

 Yellow-throated Vireo, as the following notation will 

 show: Imt th n- is a c* riuin elementary character to the 

 song of each of the birds which written music can not 

 easily express i. e., the buzz of one and emphasis of 

 the other: 



This group of three ^^ prv' 

 slurred tones Ss characteristic. 



One need not suppose for an instant, that the notes as I 

 have recorded them represent tones accurately struck 

 by the bird; they do not. But they do represent the 

 approximate swing of his slurred tones placed as cor- 

 rectly as possible upon the musical staff. 



One may think that the music looks like that of the 

 Robin; but I am quite sure that my explanations and 

 musical signs will constitute an evidence sufficient to 

 show that such an impression produced upon the eye 

 could not be other than an entirely superficial one. 



White-eyed The White-eyed Vireo is an extremely 



Vlrec uncommon bird in New England. In 



nollloracensis Campton, N. H., his voice is never heard, 

 L. 5.25 inches and in the vicinity of Boston it is very 

 May isth. rare. In northern New Jersey, however, 

 the bird is an almost common summer resident, and his 

 notes enliven the thick shrubbery and undergrowth 

 wherever there is a pond or stream with a marshy 

 border. He is also common in the vicinity of Washing- 

 ton. His colors are, gray olive-green on the back; 

 brown-olive on wings and tail; two distinct yellowish 

 cream wing-bars on each wing; the region in front of 

 and around the eye yellow; throat and under parts dull 

 white; breast and sides tinged with greenish yellow
