I'm trying to get better at my raptor identification and this is pictures I've taken of a red-tailed hawk that likes to sit up on this high capacity power line towers, to whom I've given the name of Rook. I believe it is a mature red-tail as some of the pictures indicate the red tail. The next question is whether it is male or female, my guess would be female? It's pretty hard to tell since it's so far away and guessing scale from that distance is difficult. You might need to zoom in on the pictures a little bit to tell. This is the best a 12-18x zoom gets me. My camera is more optimized for shooting high speed photography and videography.
