PERCHING BIRDS 



667. Black-throated Grekn Warbler. 



Uendroica virens. 



Range. — Eastern United States, breeding from 

 soutiiern New England, Soutii 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 arc nearly always found, and 

 always nest, in pines, eitlier groves 

 or hillsides covered with young 

 White 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, wliich they lay in June, 

 are white, wreathed and speckled with brownisii 

 and lilac. Size .60 x .50. 



668. Townsend's ^A^ARBLER. Deiidroicd 



townsendi. 



Range. — Western United States, 

 from the Rockies to the Pacific and 

 from Alaska southward; winters in 

 Mexico. 



Tills is tlie 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 througliout their United 

 States and Canadian range, the nests being placed 

 at any height from the ground and being con- 

 structed lilie tliose of tlie Black-tliroated Green. 

 Their eggs are not distinguishable from those of 

 the latter. Size .60 x .50.
