Immature male NG

7 September 1:30 p.m. 41st Street - Anacortes; 1 immature male NG; the bird was flapping as a NG can flap- with deep, rapid, and flexible wing beats. The hawk was circling over and over again at 150-200 feet elevation. I left the area with the hawk yet in the air. This is a common sighting, as NG are coming off the MT. Erie Mountain.
