Wikipedia Abstract

The snowy egret (Egretta thula) is a small white heron. The genus name comes from the Provençal French for the little egret Aigrette, a diminutive of Aigron," heron". The species name thula is the Araucano for the Black-necked Swan, applied to this species in error by Chilean naturalist Juan Ignacio Molina in 1782.
