remarkable female goshawk

On about 19 April- Pioneer Trails RV Park- Anacortes
1 female Gos . This hawk was observed under excellent visibs. The hawk was in flight soaring and gliding. This hawk had a white patch on the rump area. The bird was very large and had long wings. There did not appear to be any large area of white under tail coverts, not even a small area. Any individual who cares to call this hawk a hybrid- be my guest, but unless you can show me the laboratory report, then I will have little faith in your assumptions. A report was sent to the WOS (Washington Ornith. Society).
