Around 7:00 tonight we heard a strange call, almost like a bark, coming from a group of black locust trees near our house. The trees are about 200' from a large swamp. We got a quick look and then it flew over our house (away from the swamp) and landed in a group of trees about 400' from the house. After looking at our bird guides and a CD of recordings we think that it was a black-crowned night heron. It would be a life bird for me and my dad.
