Birds of Celebes: Ardeidae. 
Its nearest affinities are with Buhulcus ibis of Africa, Southern Europe and 
S. E. Asia 'Palestine) ; this bird has shorter toes and in summer yellow legs 
(in winter dark brown or dull blackish grey — Dresser), and some differences 
in coloration when breeding. 
The changes in colour of the bill and feet according to the season in some 
of these Eastern Herons are of a curious character; Hume has already written 
on the subject (Str. F. 1878, VI, 473, 480).

GENUS ARDEOLA Bole. 
Size small; the tarsus shorter than the middle toe and claw; the wings 
white. The latter character, contrasting with the coloured plumage, at once 
distinguishes it from the other Herons.
