WILSON WARBLER. 



685. Wilsonia pusilla. 5 inches. 



Male, with black crown patch; female, with the crown 

 greenish like the back. 



These little fly-catching Warblers are abundant in 

 the United States during migrations, being found in 

 woods or swamps, and very often in apple trees when 

 they are in bloom. They fly about among the outer 

 branches snatching insects from the foliage or blos- 

 soms, and often dashing out to catch one that is flying 

 by. Their natural pertness is intensified by their very 

 attractive plumage which harmonizes perfectly with 

 green leaves. 



Song. A simple and rather weak trill. 



Nest. Of leaves and bark, imbedded in the ground 

 under bushes on the edges of swamps or woods; eggs 

 white, specked with reddish brown ( .60 x .48 ). 



Range. Eastern N. A., breeding from the northern 

 edge of the U. S. northward; winters in Central America 

 Two sub-species are found west of the Rockies.
