Semi-Pensile, Pensile or Hanging Mesta 



627. Warbling VIreo : Viroo gllvus (Vieill.) 



AduU— Upper parts olive green or grayish green; under parts 

 white, slightly tinged with yellow ; line over the eye indis- 

 tinct grayish white. Length — 5.80. 



Breeding Range — Throughout the Eastern States. 



The nest is similar to that of the red-eyed vireo ; the eggs 

 white, spotted and sometimes blotched with reddish brown. 

 Size— .75 X .52. 



This bird is difficult to distinguish from the red-eyed vireo; 

 it is somewhat smaller, the line over the ey& less distinct and the 

 song totally different, being more prolonged and melodious. 



The breeding season begins towards the end of May. 



628. Yellow-throated Vireo: Vireo flavifrons Vieill. 



Adult — Upper parts yellowish olive ; rump gray ; ring around 

 the eye yellow; breast light lemon yellow; belly grayish 

 white; distinct white bars on wings. Length — 5.95. 



Breeding Range — Throughout the Eastern States. 



The nest resembles a good example of the red-eyed vireo's, 

 fi-om five to forty feet from the ground. 



Eggs white with a tinge of pink ; rather more thickly spotted 

 than those of the red-eyed vireo. Size — .83 x .61. 



The bright yellow breast serves to distinguish this bird from 

 other members of the vireo family ; the breeding habits are not 

 very different from those of the red-eyed vireo, except that 

 nesting begins rather later. 



629. Blue-lieaded, or Solitary Vireo: Vireo solitarius 



(Wils.) 



Adult — Upper parts greenish; head blue gray, with conspicuous 

 white ring round the eye, and white between eye and bill ; 

 under parts whitish, tinged on the sides with greenish 

 yellow; wings have two white bars. Length — 5.61. 



Breeding Range — Chiefly in the northern part of the United States, 

 and in the higher parts of the Alleghanies further south; 

 rarely in northern New Jersey.
