Great set. The second reminds me of Al Pacino saying are you talking to me? ( I think it is Al Pacino). The third one has great symmetry. If not for the minor differences one would think each is a mirror image of the other.
Thank you for the comments. It was extremely luck to be able to get the third shot. I still have a lot to learn about birds and their behavior patterns. I was at Occoquan Bay National Wildlife Refuge looking for egrets (no luck). The deer flies were swarming (they don't know what insect repellent means) and I needed to find an open sunny space. So I walked towards the end of the trail. Lo and behold, swallows. I guess you never know where opportunity will come knocking.
