Crow delivery?

Since the produce vouchers expire tomorrow and I still had two left, I headed off to Safeway again to spend $20.  In the Extra,  you see my haul.  Best news is, I received another $60 worth of vouchers to be used in the month of January!  It's worth making special trips to Safeway.

When I came back to my car, I saw a group of crows sitting in the bare branches of this tree.  They kept flying off and back, but this is the best shot of them I was able to get.  Why is it that birds won't sit for their portraits!
