A fellow photographer alerted us to this black-crowned night heron he had discovered in a tree off the water. It was nearing the end of the day and a whistle caught our attention. We couldn’t see what was making the sound until I looked towards the water and saw a man waving his arms. As we approached he pointed upwards and we saw the heron. We couldn’t have been more than 15 feet from it. I don’t know if the heron saw us but it continued to preen and we took multiple shots. It was a wonderful end to our walk thanks to the friendly stranger who generously shared his find with us.
