Although Watership Down is a peaceful habitat, Hazel realises there are no does, making the future of the warren certain to end with the inevitable deaths of the rabbits present. With the help of their useful new friend, a black-headed gull named Kehaar, they locate a nearby warren called Efrafa, which is overcrowded and has many does. Hazel sends a small embassy, led by Holly, to Efrafa to present their request for does.
