Word Origin and History for least bittern
heron-like bird, 13c., botor, from Old French butor "bittern," perhaps from Gallo-Romance *butitaurus, from Latin butionem "bittern" + taurus "bull" (see steer (n.)); according to Pliny, so called because of its booming voice, but this seems fanciful. Modern form from 1510s.
