Female.—Similar to the male, but without the beard.

Habits—This species is said to be solitary, or to go about 
only in pairs. It derives its scientific name from its habit of 
drinking by lifting the water to its head with its hands, instead 
of stooping down and applying its mouth to the water. It is 
difficult to tame, being fierce and ill-dispositioned.
