This turkey buzzard was being harassed by four magpies who were trying to steal his/her lunch. Unfortunately, they succeeded.
I was walking around the park with the k10d, A 1.4X-S on M 400/5.6, all mounted on my trusty Manfrotto 055B, and was lucky enough to spot this little drama. I took 15 images while standing on a picnic table across the river from this hoodoo (the rock formation). This is the one I like the best. It is, at the time of writing this, my desktop background.
