When I was a kid, my mother couldn’t keep me indoors. I was constantly roaming the woods and fields near our home, dragging back sick and injured wildlife — probably to the animal’s detriment. But the day Mom drew the line (“No more critters!”) was the day she saw me coming down the road with a live great blue heron under my arm. The 4-foot bird with the dagger-like beak was nearly as tall as I was.
