There were two different birds doing that exact thing this morning. I definitely have that problem. And most of the trees in my neighborhood are pecan trees that are at least half a century old, so these are some large trees.
I also have a pair of bluejays that seem to have decided I'm evil. Every time they see me, they start up with alarm calls, and of course they scare everything else away. They might have seen me holding an injured jay a couple years ago? It had probably hit a window or something, the poor thing was trying to fly but kept sort of skidding along the ground instead. I took it to a wildlife center, but of course the jays don't know that.
Edit: ah, one of my attempted pictures of a treetop bird actually worked! Sort of. It was taken by using a little device that holds my phone with the camera aligned through the lens of my (inexpensive) binoculars, and I just found this on my phone. I didn't think any of those pictures had remotely turned out.
