Kehaar - the Black Headed Gull

My riverside walk today awarded me with a nice Black Headed Gull.

Kehaar: A black-headed gull who is forced, by an injured wing, to take refuge on Watership Down. He is characterized by his frequent impatience, guttural accent and unusual phrasing. Eventually, after Hazel and the others befriend him, he flies over the countryside in an attempt to discover other warrens where the rabbits might find does to mate with. He discovers the Efrafa warren, and after helping the rabbits he flies back to the sea to rejoin his colony, though he frequently returns for a visit. According to Richard Adams, Kehaar was based on a fighter from the Norwegian Resistance in the World War II.
