Here's the dreaded "holey" main branch, having split as it fell. You can see that it split at nearly center to the branch, the hole visible earlier at approx 12 feet high visible through-&-through. Curiously, you can also see the nesting material in the even higher stem hole. I never saw any birds nesting up there, and doubt that a bunch of babies could have fledged out of there without my being aware of them (although you can see down feathers present). Most of this detail requires, BTW, that you are able to magnify the photo in your machine.
