I don't see your point? Not seeing the forest because of all the trees?
Octopussies have fun moving in weird ways, too. Also exploring, and making fun of captors!
Birds...did you know that their five feathers on the ends of their wings are the equivalent of our fingers, neurologically/network-wise? They sense the currents of the air with them.
Whatever. I think, no matter which species you are belonging to, it can be good to have these systems in more or less autonomous action, moving by themselves, while having a somewhat detached mind, soaring along, thinking about other stuff than the usual chores.
Edit: Maybe something like micro-dosing a little bit of 'Runner's high' by walking aimlessly?
When was the last time you saw a feather? (Or a bird).
Edit: Have you ever had a big white swan spread his wings, and touch his five feathers against the spread fingers of your hand? 'Gimme five' so to speak. I did.
As I did with Seagulls, Crows/Ravens, Starlings, Blue tits, Robins, city and forest Pigeons, and really long ago a common Swift, which I successfully raised.
Thinking about the possible reason you're asking:
I've stopped trying getting good pictures anyways, long ago.
I came to the conclusion that any camera, be it digital compact, action, smartphone irritates the animals. They may be curious initially, but as soon as the electronics try to 'rangefind/sharpen/focus' the picture they are gone. Or getting angry. Not even thinking of flash.
Edit: It destroys the moment. Be it by sounds, or even visible laserfingers fanning out. Or maybe distracting me from holding my internal projection of intent and movement upright. Which I'm thinking of having some impact on the goodwill of the involved animals, too.
