Birds of Celebes : Ardeidae. 
GENUS ARDETTA G.R.Gray. 
The Little Bitterns are about the size of a Turtle Dove. The hill is long 
and slender, slightly serrated; the tail short, about as long as the tarsus and 
consists of 10 feathers; the toes and claws slender; the tarsus covered with trans- 
verse shields in front and behind, or covered behind with large polygonal scales. 
No ornamental dorsal plumes. The scaling of the tarsus and the small tail 
of 1 0 feathers serve to distinguish them from Butorides. Their nearer affinities 
are with Botaurus, which differs in the characters pointed out below (p. 856).
