I saw 3 Red-tail Hawks today. I'm pretty sure they were all Red-tails. However, one was flying through the woods, fairly low, which is not something Red-tails are known for. They're circlers, or they perch high on the edge of a clearing.
It seems to go in spurts for me. I won't see any for several weeks than I'll see them everywhere. I have found a couple of places (plenty of pheasants around) where I can watch them hunt. Twice they took prey within feet of me. They come in out of nowhere and then they're gone, all in the blink of an eye.
