Apollo restored Aegypius's vision long enough for him to realize what had happened and changed all four of them into birds. The men became vultures, Timandra a sparrow-hawk, and Bulis a long-beaked bird that pecks out the eyes of fish.
Apollo restored Aegypius's sight briefly, allowing him to grasp the situation, and subsequently transformed all four individuals into birds. The men were reborn as vultures, Timandra took on the characteristics of a bird of prey like a sparrow-hawk, and Bulis evolved into a bird with an unusual beak that feeds on fish by pecking out their eyes.
