PATAGONIAN EXPEDITIONS: ZOOLOGY. 



Tarsus, i.i. 



Color. Head: Dull vinaceous brown, each feather with a terminal 

 margin and one or two narrow black bands ; this gives the whole head the 

 appearance of being finely mottled or flecked with dusky ; the feathers of 

 the crown and occiput are long and form a decided crest; the longest 

 feathers are darker than the rest and soft, almost filamentous. 



Neck : The upper neck is like the head in color ; this ceases abruptly 

 and definitely on the lower neck and the color of that part is brighter 

 vinaceous, each feather having a black spot near the tip. 



Back : The mantle greyish brown, with a black spot near the tip of each 

 feather, which is defined by a strong margin of rufescent brown. Lower 

 back, rump and upper tail-coverts uniform greyish brown, with a strong 

 olive tint. 



Tail : Greyish brown, with olive cast. 



Wings : The anterior scapulars like the mantle in color and marking ; 

 the longer scapulars and tertials dull brownish, edged with bright rufes- 

 cent brown or cinnamon ; upper wing-coverts olive-brown, with a greyish 

 cast ; the tips of the greater row of coverts are bright cinnamon and 

 form a defined border, a third of an inch wide, to the velvety black 

 speculum, the outer webs of a few of the inner feathers of which are 

 glossed with metallic greenish reflections ; the feathers of the speculum 

 are tipped with rufescent white, which forms a posterior border nearly 

 half an inch wide ; primaries dull olive-brown ; the under wing-coverts 

 greyish brown, except the central ones, which are white, as are the axillaries. 



Lower parts : The breast and abdomen whitish ; the breast more or less 

 tinged with rufescent or reddish brown ; each feather is barred with at 

 least two blackish bands ; that near the tip being like a spot of irregular 

 shape and the other bars hidden and hardly noticeable ; this becomes 

 obsolete barring on the belly ; the vent and under tail-coverts are dull 

 olive-grey and some of the feathers of the coverts are strongly shaded 

 with cinnamon ; sides and flanks dull olive-grey. 



Bill : Yellow, with the culmen shaded into black ; the nail definite black. 



Feet: Blue lead-color. 



Iris : Hazel or carmine. 



The adult female is like the male, but is somewhat smaller and duller 

 in color. 



Young birds of the year are like the female, but all the colors are duller
