Fooled

I was hawking in North Central PA. Two raptors were heading toward me. They had long wings, with zero dihedral, and were flying wing tip to wing tip. The hawks were grey; No doubt female goshawks. But no! They were Red- tailed hawks.

In Yuma in winter, on high, was a gull or a white falcon, maybe a Gyr  falcon. About a day later, I realized the bird might have been a White- tailed hawk. NB.
