THE BLUE-GRAY GNAT-CATCHER. 



Occasionally, In Northern Ohio, the nervous flitting 

 of the Blue-gray Gnat-catcher (Polwptila tceruUa) would 

 attract me. This is about the northern boundary of its 

 habitat, but it extends westward to the Pacific, and is strictly 

 migratory. Only 4.50 long, and much of this lineal dimen- 

 sion consisting of the tail, it is but 6.00 in extent The 

 color is bluish-gray above and bluish-white below; head 

 bluest, with black front and eye-brows in the male; wings 

 brownish-black, with secondaries near the body edged with 

 white; the tail, which is longer than the body and a little 

 rounded, black; the exterior feathers white nearly to the

 slender and black. Warbler, Titmouse and Flycatcher in

 diminutive body, however, and long rounded tail giving 

 it a rather Tom-tit appearance; its plain drab-like colors 

 also remind one of the Titmice. Its common note, lsee,tsee,

 tree, anywhere from ten to fifty feet from the ground, it is 

 closely felted together of the softest materials of the forest 

 bud-scales, dried blossoms, and the delicate cottony sub- 

 stance which envelops the unfolding fronds of ferns, with
