1 long-winged accipiter; soaring, then flapping. EOB 150 feet. The bird came directly overhead, in a glide. Now the bird showed medium-length wings; this was because of the forces placed upon the wing. The ventral area of the bird was grey; with the chest and belly being robust. The folded tail was blackish. The bird flew eastward, and I was looking up the back of the bird, between the shoulder blades. The bird had very deep wing beats, yet the wings were not flexible, but stiff, much as a Cooper's Hawk. The wing beats were very rapid. It appeared the bird cleared the golf course, and was now over the desert scrub. The bird was now buteo-like; soaring, flapping, and circling. OT 1 minute; an unusual observation. The bird was NG; probably female.
