olive-green, and tipped with whitish ; the greater coverts are dusky, the 

 outer ones immaculate, the inner ones have white tips, which form a 

 hand on the wings. The inferior wing coverts, and all the under surface 

 of the wings, are more or less whitish-gray ; the primaries are dusky, 

 with a narrow greenish-yellow outer margin, wider at base, and atten- 

 uated to the tip, where it is obsolete. The secondaries are dusky ; on 

 the outer web they are whitish near the base, then black, then with a 

 greenish-yellow margin extending nearly to the tip ; the margin of the 

 inner web is white ; the secondaries nearest to the body are, moreover, 

 whitish on the terminal margin. The tail is emarginated ; the feathers 

 are dusky olive-green on the margin of the outer web ; the inner mar- 

 gins, with the exception of the two middle ones, are whitish. 



Until their first moult, the young of both sexes are much like the 

 adult female, except in being destitute of the yellow spot on the crest, 

 which is greenish-olive. In this state, however, they are not seen here, 

 as they breed farther to the north, and moult before their arrival in the 

 autumn.

Although this species has long been known to naturalists as an in- 

 habitant of South America, and its name introduced into all their 

 works, yet they have given us no other information concerning it than 

 that it is black, with a yellow head and neck. It was added to the 

 Fauna of the United States by the expedition of Major Long to the 

 Kocky Mountains. 



The female has been hitherto entirely unknown, and all the figures 

 yet given of the male being extremely imperfect, from the circumstance 

 of their having been drawn from wretchedly stufied specimens, we may 

 safely state, that this sex also is, for the first time, represented with a 

 due degree of accuracy in our plate. The figures published by Edwards
