RED NG

18 October 11 A.M. Saint Mary Church Anacortes
1 mature female NG circling over and over again at 300 feet elevation near downtown Anacortes. The hawk went back toward MT. ERIE circling at 1000 feet elevation. Observation time 10 minutes. The underwing was not enhanced by the bright sun. I will bet that the underwing coverts were RED. Is this the same NG that I have , to my knowledge, observed only once, in February 2002? That NG had RED underwing coverts.
