Watership Down
Hazel later rescues a big gull named Kehaar, who has been hurt by a cat. After nursing Kehaar back to health, Keharr agrees to help the rabbits for the time being in return for their kindness toward him. After being asked by Hazel to check out of the area, Kehaar finds a large warren called Efrafa to the South of their position. After hearing that Efrafa is large and too crowded, Hazel sends four rabbits to Efrafa to ask if they could bring back some does to their warren.
