I checked out a Great Blue Heron rookery in southern Wisconsin today to see what was going on. Lots of young and getting to have some size to them too. Some adults came with sticks for ongoing nest maintenance. Other adults came to the nest and regurgitated food in to the nest for the young to eat. Always amazing when I sit back and watch all these things happen. A beautiful sunny day with low winds and mild temps. Images were taken on May 19, 2016.
