also a Smithsonian tag reading 



"This is probably a new species. It is most like 

 traillii in coloration but has outer v;ebs of 

 exterior rectrices v^iite, as in obscurus . 



This is the eastern race of traillii .ftot sexed - 

 evidently a male. So grease stained and dirty 

 that most of the color characters are lost - how- 

 ever the wing bars are whitish, not buffy, and the 

 bill is small. The outer web ia by no means pure 

 white, I can nearly or quite match it with several 

 eastern specimens of traillii*
