In plain words
Yaśōdā calls: "When the treacherous demon came in the form of a bird that feeds in the marshes [the crane Baka], he saw him and, taking him for a mere bird, tore his beak apart in a moment: come and comb that child's hair, crow! Comb the hair of him who drank at the breast of the demoness [Pūtanā], crow!"
