In the evening, generally in the hour or so before sunset, there is a steady stream of crows, always flying in a generally southward direction. We often see them from our back yard in relatively small but significant numbers. As I was driving home this evening, enjoying the faint coloring of the eastern sky ahead of me, there were a lot of crows flying from left to right (north to south) across the road as I neared the bridge over Rock Creek. It’s hard to get a photograph of a flock of birds that is as impressive as the flock, unless there really are a lot of them, so this photo may not look like much. I was sitting in traffic and they just kept coming, at about this volume, the whole time I watched. I wonder where they go to roost. I’m glad it isn’t in my back yard.
