132 BIRDS OF NEW ENGLAND AND EASTERN NEW YORK 



The White-eyed and Solitary Vireos both have a strong 

 yellow tinge on the sides of the belly, but in the former 

 the line to and around thi eye is yellow, while in the lat- 

 ter it is white. The White-eye is small and is rare north of 

 Connecticut ; the Solitary is larger and breeds in northern 

 New England, passing through southern New England and 

 the Hudson Valley before the White-eye arrives.

 and the sub-Canadian areas, but is a common migrant 

 through the rest of New York and 

 New England, passing north in

 in May, and returning late in Sep-

 a migrant it frequents almost any

 into orchards and about houses. 

 It breeds in deep, cool woods, either evergreen or deciduous, 

 preferring possibly the former. It is much less common 

 • than the Red-eye, and its voice is louder and richer, so that 

 as one passes along a woodland road, the Solitary Vireos 

 inhabiting the region are easily noted, and are found to be 

 separated by far greater intervals than the Eed-eyes. The 

 song resembles that of the Eed-eye in form, but it has a 

 sweeter, more appealing tone. Certain passages are charac- 

 teristic ; one is a " double note," that is a phrase repeated
