Partridge. 



First Plumage : — In the specimen before me, a male, taken October 

 29, in Texas, the adult plumage is just coming out, but does not yet 

 conceal the first growth of feathers. The bird, I should judge from the 

 size of skin, the feet, and the bill, to be nearly full grown. Top of head 

 light brown, darker in centre, with only the slightest tinge of the drab or 

 light blue common to adults in fresh plumage. The crest is conspicuous 

 and peculiar, forming two prongs or forks, and is composed of four 

 brownish white feathers about three-quarters of an inch long. These 

 crest feathers correspond to the longest and white-tipped ones of adult, 

 but, unlike them, are not ragged or hairlike, being firmly rounded, nearly 

 as much as the plumes of the common Night Heron. The dark brown 

 coverts (so to speak) of the crest are not conspicuous, being just a little 

 longer than the feathers of the crown, and are evidently just growing out. 

 The feathers of back are light brownish drab, without edgings, but with 

 white shaft-lines enlarged at the end. The coverts and scapulars are 

 strongly waved with dark brown and rufous, having heavier white shaft- 

 lines than on the back. The tertiaries have the white shaft-lines and 

 waves only on lower end of feathers ; the outer edges being strongly mot- 

 tled with brown and gray. The wings are plain brown, the longest quills 

 being faintly edged with spots of light fulvous gray. Rump brownish 

 blue; tail dark grayish blue barred and speckled with dark brown and 

 ashy white. Throat light bluish gray; the feathers having small dark 

 centres, thus giving a faintly speckled appearance. Breast dark drab with 

 all the feathers showing white shaft-lines as on back. Belly. crissum,and 

 tibia dingy yellowish white, thickly barred with brown and fulvous. Bill 

 very dark brown above and pale below. Feet yellow. 



Catharista atrata. Black Vulture. 



Dozvny Stage : — -Entire bodv densely covered with long silky down of 

 uniform light fulvous color. Throat and lores bare. The whole top of 

 the head is covered with a thick down of two distinct lengths, the longer 

 of which is much shorter than the body down ; looking at the head from 

 above, this longer down is seen to grow- in such shape as to torm a patch 

 having the outlines of a perfect spear-head ; the spear-ooint stands toward
