Alright, took some pictures over the past few days of my progress and while out cutting I spotted an oak(?), that looks close to death. The one leader died off and the other is alive for now. I was planning on dropping it the usual way but putting a hitch chain up about 5 ft(I usually do my felling cut around 3 ft) wrapped around the tree to keep it from barber chairing, let me know what you think.
I'm seeing a red maple, bucked, in first pic, sugar maple in the last one. Sure doesn't look like any oak to me. Should be immediately obvious once you put a saw into it- it'll make the saw work to spit nice white chips. Rather than the chain thing (just don't like chain around saw chain) I'd go for a boring backcut.
The first was the beech I was cutting up. It's all in rounds now, slowly getting split and stacked. And it may full well be a maple but I don't see any maple leaves around it. I'd try the bore cut if I was confident in my ability to do one.
Can't hurt might help. If you are worried about the caw hitting chain, use an industrial ratchet strap.
