Over time, the vulture had begun to return at the same time every day, which was when Tumbleweed set out with a scrap of meat to be left on a boulder. For a week Tumbleweed had been leaving offerings in the same spot, and the boldest of the vultures had come down to seize it for himself, sending others scattering with a wave of her gigantic wings. He only ever brought enough for one- and in doing so, had managed to suss out which of the circling birds was the one in charge, or least likely to be challenged by the others.

He'd followed him back into the desert one day, to see where he nested. It was a mass of sticks and feathers, high in a tree, difficult to spot as all the trees in the area were dead and dried out as well.

He returned to the boulder in the morning, carrying with him both a fresh jackrabbit and a piece of turquoise, feeling that it was time a form of trade be developed now that he had fed the bird 7 solid meals.
