Later she returned and I spotted her in an old squirrel's nest finishing her kill but, this time, being true to form, she was gone by the time I got my camera. What I noticed, that I had never seen before, were Cardinals and House Finches sitting in the branches around her as she ate. I assume they were waiting to grab a meat snack or two when she was done. She was completely oblivious to their presence.
Photographing birds in the backyard, even in the winter, can be a challenge because the tree stand density is enough to make it difficult to find a clear view of the bird without interfering small branches between you and the subject. Usually in the summer the leaf canopy is too thick to see even a fraction of the birds hanging about in the trees.
