Translation of "Clanging" in Portuguese

When straight, down-swooping from the hills meanwhile / the Harpies flap their clanging wings, and tear / the food, and all with filthy touch defile, / and, mixt with screams, uprose a sickening stench and vile.

Mas as harpias chegam de repente, / vindas dos montes em medonho voo; / com grande estrépito adejando, pilham / nossa comida e tudo contaminam / com seu contato imundo; ao cheiro insuportável / juntam-se agudos e sinistros gritos.
