Shooting handheld with an effective lens of 650mm+? The 300mm lens is great glass, if it's Nikon. Perhaps if you'd shot without the extender at a lower ISO you could have gotten a sharper image of the owl. Sharper images always crop better.
I think that you are right. When the opportunity presented itself, that is what I had on camera. I had it set on auto ISO and the light was low. I was going to use a tripod too but I did not get the chance - the owl was more skittish than I thought he should be.
