My first 21 years were spent on the North Fork looking at this and that. While I specialized in birds, learned the mammals — there weren’t that many — I also knew the local frogs, turtles, newts. and fish, which I learned by catching them. I knew as many garden and farm plants as native plants, I knew that Japanese honeysuckle was not American, and I knew about a handful of other invasives. I knew blueberries, beach plums, black cherries, because I picked them and ate them. I knew poison ivy because it made you itch like the devil.
