624. Red-eyed Vireo. Vireosylva oiivacea 

 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- 

 sistent 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 philadelph/ca 



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 



Warbling Vireo. 



gili 



Vireosylva 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 aboul 

 , t among the foliage, peering 



»-• under every leaf for lurking 



insects. The eggs are pure 

 write, spotted with brown or 

 White reddish brown. Size .72 x .52.
