ID tip
The adult plumage is gray with fine zigzag barring, with a pale underside, standing about 32 centimetres (12+1⁄2 inches) in height. Juveniles have a dark back with a brown head and underside. Due to its appearance it was often assigned to the tiger herons (Tigrisoma and allies). But in fact, it is a true bittern, having like these only 10 rectrices (other Ardeidae have 12) and being unequivocally placed in the bittern lineage by DNA sequence data too. Short legs and necks and cryptic plumage may thus be plesiomorphic among Ardeidae in general.
