WILSON'S WARBLER * 339 



only the memory of the delightful little songster 

 himself. 



Wilson's Warbler: Wilsonia pusilla. 

 (See Fig. 182, p. 346.) 



Adult male, cap black, upper parts bright olive-green ; under 

 parts bright yellow ; no marks on wings or tail. Female and 

 young, similar, but generally without cap. Length, 5 inches.

 winters in Mexico and Central America.

 192) ; the Black-throated Blue by the colors that
