Golden-cheeked Warbler 



DENDROICA CHRYSOPARIA Scl. and Salv. Plate XIV 



Distinguishing Characters. — The Golden-cheeked Warbler is to be con- 

 fused only with the Black-throated Green Warbler. Adults of both sexes 

 are sufficiently unlike not to require detailed comparison. Young females may 

 be distinguished by the fact that in chrysoparia the belly is white while in 

 virens it is tinged with yellow. Length (skin), 4.60; wing, 2.50; tail, 2.10; 

 bill, .40. 



Adult ^, Spring. — Median frontal stripe yellow, rest of upperparts shining 

 jet black without olive markings; tail blackish two outer feathers largely white 

 on inner web apically, and on outer web, basally, third feather with white 

 on inner web only, less in extent; wings edged with grayish the median coverts 

 broadly, the greater coverts more narrowly tipped- with white; cheeks and 

 line over eye yellow; a blackish line through eye from bill to nape; throat 

 and upper breast black; sides heavily streaked with; black, rest of underparts 

 white. 



Adult c7. Fall. — Not seen, doubtless not materially different from adult J in 

 Spring. 



Young c?. Fall. — Resembles adult 2 in Spring but is more heavily streaked 

 above, the yellow of the sides of the head is brighter and more extended, the 

 throat and upper breast are black tipped with yellow or whitish. 



Young <?, Spring. — Similar to young d in Fall but tips on black of throat 

 and sides smaller or absent; upperparts with narrower greenish edgings.
