The Marsh Hawk courses to and fro over field and 



meadow, like a Gull over the water. He never sails,

 with rapidly moving wings. Then, dropping lightly down 

 on some unsuspected victim below, he returns to the bare 

 limb or stub he uses for a lookout station, uttering an 

 exultant lilly — IvUly — I'llly as he- flies.
