This morning, while getting my Bird RDA, I came across a Cooper's Hawk. It was hidden well enough that I would not have seen it had the birds not found it for me. There was a cat stalking nearby and a Mourning Dove flushed to get away from it. When it tried to land on a fallen tree, it found that its desired perch was actually a Cooper's Hawk rather than a branch. I think the hawk was too surprised by the aborted landing to take advantage of the situation.
