heron

Boyd’s Bible Dictionary:

A large aquatic bird, pronounced unclean
(Lev. 11:19; Deut. 14:18).

Concise Bible Dictionary:

A bird that was unclean to the Israelites. The name anaphah cannot be identified, but several species of heron are found throughout Palestine, which are doubtless included because of the words “after her kind.” The Ardea cinerea is a heron common in Palestine. They live upon fish, frogs, and reptiles. (RV margin has “ibis.”) (Lev. 11:19; Deut. 14:18).
