A flock of pigeons have moved into the rural area where I live, much to the pleasure of the red-tailed hawks (and feral cats). I managed to get my camera out (for the first time in a while--life gets in the way sometimes) and get a few shots of the pigeons' aerial dancing. I just missed a red-tailed hawk bringing down a pigeon, but did get a few of him on the ground with it, and a bigger (much bigger!) hawk laying claim to it.
This photo is part of the dance. Amazing that they just don't run into each other--although when the hawks showed up, they got a little crazy, losing the rhythm and direction synchronicity. Still, no collisions. Fascinating!
