DENDROICA AUDUBONI AUDUBONI (Townsend). 

 AUDUBOlf'S WAEBIEK. 



Similar to D. coronata, but throat yellow (in adults') instead of white, 

 and with more white on inner webs of reotrices; adult male with auric- 

 ular region bluish gray instead of black, with a large and conspicuous 



' In some young females in their first autumn or winter there is absolutely no trace 

 of yellow on the throat. Such specimens can be distinguished from immature 

 females of D. coronata only by the decidedly greater amount of white on the inner 

 webs of the outermost rectrices, D. auduboni having four to five thus marked, while 

 in D. coronata there are only two to three. As a rule, immature specimens of D. 

 auduboni are very slightly grayer brown, and less distinctly streaked, above, but the 

 difference is by no means constant.
