I found an adult Black-crowned Night-Heron late this morning at Lock 2 of the Champlain Canal in Mechanicville. It was perched on a rock below the dam very near the parking lot after crossing the bridge. I also spotted the 2 Little Blue Herons previously reported. One was on the Rennselaer side of the river and the other on the Saratoga side. I posted a photo of the Night-Heron.
