nostrils in front, and passing under and beyond the termination of 

 them at the sides, but seldom reaching the corner of the mouth, 

 except in very old individuals, in which this mark extends under 

 and behind the nostrils, crosses the base of the bill next the fore- 

 head, leaving only the central part of the bill (between the nostrils) 

 and the nail black ; which latter part is sometimes, though rarely, 

 white ; legs and feet, reddish orange ; wings, when closed, reaching 

 2 inches beyond the tail. The young of this species are darker,

 young of any of the other species.
