The Corncrake has a more uniform brownish-black upperpart with chestnut wing patches, while the Sora displays a distinctive gray face and breast with a contrasting black face mask. Vocalizations are also a key differentiator, with the Corncrake's loud, grating call contrasting with the Sora's descending whinny.
