PERCHING BIRDS 



White 



667. Black-throated Green Warbler. 



Dendroica virens. 



Range. — Eastern United States, breeding from 

 southern New England, South Carolina in the Al- 

 leghanies, and Illinois north to Hudson Bay; win- 

 ters south of the United States. 



These common eastern birds are 

 similar to the last but the entire 

 upper parts are olive greenish. 

 They are nearly always found, and 

 always nest, in pines, either groves 

 or hillsides covered with young 

 pines. The nest are usually placed 

 out among the pine needles where they are very 

 difficult to locate, and resemble nests of the Chip- 

 ping Sparrow. I have found them at heights rang- 

 ing from six to forty or fifty feet from the ground. 

 The three or four eggs, which they lay in June, 

 are white, wreathed and speckled with brownish 

 and lilac. Size .60 x .50. 



668. Townsend's Warbler. Dendroica 



towns endi. 



Range. — Western United States, 

 from the Rockies to the Pacific and 

 from Alaska southward; winters in 

 Mexico. 



This is the common western rep 

 resentative of the last species, and 

 is similar but has black ear patches 

 and the crown is black. They nest 

 in coniferous woods throughout their United 

 States and Canadian range, the nests being placed 

 at any height from the ground and being con- 

 structed like those of the Black-throated Green. 

 Their eggs are not distinguishable from those of 

 the latter. Size .60 x .50.
