The Harpies (by name Calaeno, Aello, and Ocypete) appear in the story of Jason and the Argonauts. The blind King Phineas of Thrace is harassed by these bird-women monsters who pollute his food every day until they are driven away by the sons of Boreas to the Strophades islands. The Harpies also show up in Virgil/Vergil's
Aeneid.
Sirens share with Harpies the trait of being bird-women combinations.
