John, Barometers, laws and guidelines aside for a minute - how on earth did your Mavic not spook these geese?? I was almost expecting one to get spooked and fly into it! Nice vid BTW..
Yeah, I've had this question from others.
At this river it's kinda noisy, so I think these birds have grown accustom to noise. There's a very busy
14 lane freeway about 100yds away that's rather loud, and the river running adds to that background noise. The Mavic is noisy, but less than Phantom by far, and it's smaller and lighter, which creates less prop down draft, which can spook them. I wouldn't attempt this with my
P4P, it wouldn't work well, not to mention my Mavic has refresh and my Phantom doesn't. I'm a little more brave with the Mavic because of refresh.
This is the 3rd time I have flown this area in 3 months, they may be getting use to me, I'm not sure, but I noticed in this flight they seem to be more tolerant in general. I approached them very slow in tripod mode, at low altitude, about 2-3' above the water. I was mostly concerned with the Geese, as they can get aggressive. I had to anticipate their moves, and there were a few times I thought they might charge the drone, but they never did. When they start raising and lowering their head up/down up/down (Ref @ 2:25), while looking right into the camera, I don't get closer because that's the sign it's not a happy camper about my presence. These Geese wander all over the regional park next door, you can walk right up to them and they don't get spooked, they seem pretty acclimated to humans, but you do need to be careful, they can turn on you. Geese move slower because they're big and heavy. Even with the 200ms video latency, I'm sure I can avoid them if they charged me, even in tripod mode, with a short 3' ascend. They cannot fly straight up like a duck or other birds, it takes them a while to get up in the air, like the Spruce Goose.
