624. RED-EYED VIREO. Vireosylva olivacea 



Range. United States, east of the Rockies, 

 breeding north to Labrador, Manitoba and Brit- 

 ish Columbia. 



This is the most common of the Vireos in 

 the greater part of its range and is a most per- 

 pistent songster, frequenting groves, open 

 woods or roadsides. Their eyes are brown, 

 scarcely if any more red than those of any 

 other species and I have yet 

 to see one with red eyes out- \ 



side of mounted museum spe- 

 cimens. They swing their 

 nests from the forks of trees 

 at any . elevation from the 

 ground but usually below ten 

 feet, and I have found them White 



where the bottom rested on the ground; they 

 are made of strips of bark, fibre, etc., and often 

 have pieces of string or paper woven into the 

 sides; they are one of the most beautiful of 



bird homes and are woven so strongly that old 



nests hang to the branches for several seasons. 

 Red-eyed Vireo Their three or four eggs, often accompanied by 



one of the Cowbirds, are laid in May or June; they are white, sparingly specked 



with blackish brown. Size .85 x .55. 



625. YELLOW-GREEN VIREO. Vireosylva flavoviridis. 

 Range. Southern Texas and southward to South America. 



Similar, to the Red-eye but greener above and more yellowish on the sides. 

 The nesting habits are the same and the eggs indistinguishable from those of 

 that species. 



626. PHILADELPHIA VIREO. Vireosylva philadelphica 



Range. Eastern United States breeding from northern New England and 

 Manitoba northward. 



This species is much smaller than the Red-eye (length 5 in.) 

 and is yellowish below, and without black edges to the gray 

 ; crown. Their eggs do not dif- 



'^^^^^ fer from those of the Red- 

 eyed Vireo except in size, 

 averaging .70 x .50. 

 White 

 627- WARBLING VIREO. Vireosylva gilva 



gilva. 



Range. North America east to the Plains, 

 breeding north to Labrador. 



This Vireo is nearly as abundant as the Red- 

 eye but is not generally as well known, prob- 

 ably because it is usually higher in the trees 

 and more concealed from view. Their nests 

 are like those of the Red-eye, but smaller and 

 usually placed higher in the trees. The birds 

 are even more persistent singers, than are the 

 latter but the song is more musical and de- 

 livered in a more even man- 

 ner, as they creep about 

 among the foliage, peering 

 t - * under every leaf for lurking 



insects. The eggs are pure 

 write, spotted with brown or 

 White reddish brown. Size .72 x .52.
