Nicely done. I am fortunate to have Barred Owls close to my house (though have lost a few recently to rodenticide poisonings). I always love photographing these guys and have had encounters where they've flown right to my feet...remarkable.
In light of your comments about too-slow shutter speeds, let me suggest a couple of tips for sharper results. This will take some practice and lots of trial and error so you will need access to the owls. If you've found them once, hopefully you will do so again. Anyway, the irony of it is my better perched Barred Owl shots have been achieved with ridiculously low shutter speeds. Owls, of course, will hold themselves incredibly still, allowing this. Therefore, if you can catch them in one of those still moments, you can go very slow. I've had tack sharp images with fully one second exposures but my usual method is with speeds slower than 1/20th, depending on the light . My setup has been to use both the D500 and D850 in live view mode, tripod mounted, with your lens of choice and a remote trigger release (I use a Vello Freewave Micro which is very reasonably priced). I have used both AF-S and AF-F and typically, Normal -area AF. Position the single point over your targeted subject within your composition and then use the remote release to trigger your shot. There are some enhanced advantages using a D850 which I'll hold on as your stated body is a D500.
Given you're frequently working at the corners of the day with Barred Owls, light is almost always a challenge. With shutter speeds typically slower than 1/20th or 1/10th of a second, it allows me to keep the ISO respectably low. When the owls hold still, the results can be magical...they so much as twitch and it's then a blurred mess. I also always turn off the lens' vibration reduction at these very slow speeds as it otherwise introduces motion blur. The following two shots were taken about a minute apart, shortly before sunset, both with identical settings (ISO 180, 600mm, f4), the key being the shutter speed at 1/8th of a second.
Hope this gives you a few ideas and wish you continued good luck with the Barreds.
