Dy alwad glywir hanner dydd Fel ffiwt hyfrydlais uwch y rhos Fel chwiban bugail a fo gudd Dy alwad glywir hanner nos; Nes clywir, pan ddwysa dy sun Cyfarth dy anweledig gun. Dy braidd yw'r moel gymylau maith, A'th barod gun yw'r pedwar gwynt Gorlanna'th ddiadelloedd llaith, I'w gwasgar eilwaith ar eu hynt Yn yrr ddiorffwys, laes, ddifref, Hyd lyfnion hafodlasau'r nef. The Curlew Your call is heart at mid-day As a sweet-voiced flute above the moor, As the whistle of an invisible shepherd Your call is heard at midnight. Until one hears, as your sound intensifies, The barking of your unseen dogs. Your sheep are the boundless clouds, Your ready dogs the four winds Penning your damp flocks To scatter them again A silent and restless herd Across the heavens' flowing meadows.
