2 60 BLA CK- THR OA TED BL UE WARBLER. 



the Motacilla vermivora of Turton having the bill exactly of 

 this form. The habits of these birds partake a good deal of 

 those of the titmouse ; and in their language and action they 

 very much resemble them. All that can be said of this 

 species is, that it appears in Pennsylvania for a few days about 

 the last of April or beginning of May, darting actively among 

 the young leaves and opening buds, and is rather a scarce 

 species. 



The golden-winged warbler is five inches long, and seven 

 broad; the crown, golden yellow ; the first and second row of 

 wing coverts, of the same rich yellow ; the rest of the upper 

 parts, a deep ash or dark slate colour ; tail, slightly forked, 

 and, as well as the wings, edged with whitish ; a black band 

 passes through the eye, and is separated from the yellow of 

 the crown by a fine line of white ; chin and throat, black, 

 between which and that passing through the eye runs a strip 

 of white, as in the figure ; belly and vent, white ; bill, black, 

 gradually tapering to a sharp point; legs, dark ash; irides, 

 hazel. 



Pennant has described this species twice, first, as the golden- 

 winged warbler, and immediately after as the yellow-fronted 

 warbler. See the synonyms at the beginning of this article.
