392 KINGLETS AND GNATCATCHERS. 



known species are found in the New World ; (3) the Polioptilmm, or 

 Gnatcatchers, an American group containing about fifteen species, 

 three of which are found in the United States. 



The Kinglets and Gnatcatchers are active little birds, and con- 

 stantly flit from limb to limb in their search for food. They are pos- 

 sessed of decided character, build remarkably beautiful nests, and some 

 species are noteworthy songsters.

This Kinglet resembles in habits its Ruby-crowned cousin, with 

 which during the migrations it is frequently associated. Its notes, 

 however, are quite unlike those of that species, its usual call-note being 

 a fine, high ti-ti, audible only to practiced ears. In his extended ac- 

 count of the nesting habits of this species, as observed by him in 

 Worcester County, Mass. (Auk, I. c), Mr. Brewster writes that its song 

 " begins with a succession of five or six fine, shrill, high-pitched, some-
