I got lucky this afternoon! Duluth is at the extreme northern edge of the Green Heron’s range. This bird is not too common up here. I was actually watching another bird with my binoculars when I noticed a “mound of feathers” deep in a tree nearby. Eureka! A Green Heron’s nest with four chicks.

Here is the range map provided by the Cornell School of Ornithology. I live at the tip of Lake Superior, which is just barely in this heron’s range.
