1 female NG

7 November 2006 3:30pm. RVR
1 female NG; EOB 200 feet. OT 2 minutes.
The bird was circling and flapping. Then the bird went into a long, shallow, stoop-glide, for a least 1/2 mile. 30 minutes later, I went on bike, with camera, to try and locate bird. 15 minutes later at 4:15pm., the bird was perched on telephone pole, near Rita Road and RT.10. The bird was a mature female NG. I must check my notes of last winter - that was when we saw a possible large accipiter, during near -dark conditions. We were coming from diner, at the Fry's Complex Area.
