Wild cherry. One way to check if you see one without leaves or berries is to scratch the bark off a stem. It will smell of almond extract or cyanide.
Thats interesting. I have cut a few this spring at the farm , didnt spray stumps as I read that deer will browse new growth. I will try the scratch and sniff test. If that fails I will have my buddy eat a few berries and seed , will report back….
