First, legalities: While the description you offered would seem to be a legal activity, you'd be well advised to read this:
https://www.animallaw.info/statute/us-h ... unting-actThe federal Airborne Hunting Act prohibits "hazing or harassing" game animals. This does NOT necessarily have to be for the purpose of hunting, by the way. So, just be aware that this statute is out there. You'll likely never be cited for just frightening a herd of elk, BUT if that were to happen in view of a certain "flavor" of citizen, you might nonetheless be subjected to some unwanted legal attention. And it doesn't have to be "intentional" necessarily.
Second, I spent a full career doing specifically this kind of flying, and could name a significant number of people I've known who died doing this kind of flying.....including a few with a LOT of flying experience (at least one with over 20,000 hours).
The Internet is not a good place to learn aircraft coordination, the effects of wake turbulence, low level turbulence, the effects of distraction, wind, etc, etc. I have read a lot of BS on this topic on several forums...so be careful.
Working an airplane close to the ground, in ground reference maneuvering is not rocket science, but there a number of variables that complicate the process. One of the big ones is distraction.
I hear lots of people argue that you MUST have an observer.....and another set of eyes MAY help. But, MUST??? Not in my opinion.
Why? The argument seems to be that if the pilot is looking at the critter or the ground, searching for a critter (or other subject) he's seriously endangering his life and craft. But, Explain to me how the pilot can maneuver the aircraft with reference to the ground or to a critter on the ground without looking at same.
I can tell you that the wrong observer can be more of a distraction than you can imagine.
But, my point is that the pilot MUST focus on the ground, and that critter if he's going to succeed in this endeavor. So, how to accomplish this?
I maneuver so as to
separate the maneuvering from the "observing".
You can do this by flying figure eight patterns, racetrack patterns, or 270 degree turns. In each of those situations, ideally, the plane will be in wings level, u accelerated flight as you pass over the subject of your attention.....at which point the plane will pretty much fly itself, if properly trimmed.
Once you're past the subject, you can once again devote most of your attention to flying the plane. I say most of your attention, because you still have to maneuver the plane back around to the point for the next pass, but that's just basic navigation.
I have spent many hours circling "things" and it can be done safely, but again a lot of folks have died doing so. The aerodynamics of circling at low level are a lot more complex than most pilots think. And, many of us who've spent many hours circling have no doubt at times been VERY close to the edge and never realized it.
Stall speed while accelerated, combined with gross weight, a bit of momentary uncoordination and an encounter with ones own wake all can align to introduce you to your maker.
As I noted earlier, don't crash...it'll screw up your whole hunt.
Funerals have a tendency to do that.
