Dad got a Great Gray mounted in the 80's, found a root on a brush pile with some neat burls and knots. Cleaned it up, accented it with a propane torch and varnished it. Same for his Rough legged Hawk. Very 80s style but just to offer ideas....
He since transferred them to me and I've pulled the Owl off the root, just trying to find the right branch that is going to anchor solid to the wall with out needing a plaque or baseplate and two just enough character to look cool but not over do the display.
Dad had an Eagle too, let us pick the pose but the taxidermist had his own ideas and ran an absolute muck on the job, it was dubbed the cross eyed firechicken.
Have fun with the project.
