MACQUEEN’S BUSTARD. 
Otis macqueeni 7 &. Gray. 
Adult Male: “In general character of plumage resembling 
Otis undulata, but differing as follows: the crest is scarcely 
as full and most of the feathers are dlack on the terminal 
portion ; the back is quite differently marked from what it is 
in Otts undulata, being finely vermiculated with black on 
rufescent ochreous ground, the markings here and there col- 
lecting so as to form irregular blotches ; tail marked with only 
three blue bars, the basal portion being pale ochreous-rufescent ; 
under parts as in Ovzs undulata, but the elongated feathers on the 
lower throat are blue-grey, and not white; soft parts as in O. 
undulata. ‘Total length about 26 inches; culmen 1°7 ; wing 
I5°4; tail 8°6 ; tarsus 39” (Dresser). 
Adult Female: “ Differs in being rather smaller in size 
and in having the crest and ruff less developed ” (Dresser).
