 a few times in various parts of the state. 



Nest In low bushes near the ground. Chapman says, "Little 

 seems to be known about the nesting habits of this Warbler."

 the foliage of trees, seeming to have a special fondness for aphides, 

 forty-two of which have been taken from the stomachs of three of 

 these birds." (Weed and Dearborn).
