Snowy Egret

Egretta thula

The snowy egret is a small white heron. The genus name comes from Provençal French for the little egret, aigrette, which is a diminutive of aigron, 'heron'. The species name thula is the Mapudungun term for the black-necked swan, applied to this species in error by Chilean naturalist Juan Ignacio Molina in 1782. Source
