stumpy75 may be correct that there are three different subjects in the three different pictures. Top one is a hickory, but I can't name the species; upstate NY might be out of pecan's range too. Middle one is a vine ( poison ivy ) growing up a tree which I can't identify; bark could be a maple, hickory or oak. Third one, the leaflets do not have serrated margins like the hickory in the first pic; definitely not the same tree as no. 1, could maybe be walnut, I'm not sure. There are some sugar maple leaves in the background, plus others. What you have there is a mixed hardwood forest.
