PRAIRIE WARBLER. 



673. Dendroica discolor. 4% inches. 



Above greenish with chestnut spots on the back; 

 i6elow yellow with black markings; female paler. 



These are very locally distributed birds and will often 

 be found breeding abundantly in a small patch of brush- 

 covered pasture, while many others apparently just as 

 well suited for their purposes will be shunned by them. 

 They are very active, flitting rapidly from one bush to 

 another, the male occasionally mounting to a bush top 

 to hurriedly deliver his song, then diving out of sight 

 below the foliage. 



Song-. — An energetic, rather harsh "zee-zee-zee-ee" on 

 an ascending scale. 



Nest. — A neat cup of grasses and vegetable fibres, 

 lined with black rootlets or horsehair; located in low 

 shrubs or bushes from one to two feet above ground; 

 eggs whitish with blackish-brown specks about the large 

 end (.65X.48). 



Range. — Eastern U. S., breeding from the Gulf to 

 Massachusetts and southern Michigan; winters in the 

 West Indies.
