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 

 wood 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 fly- 

 ing 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 (,60x.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.
