We have thousands around here in South Dakota, in my experience flying around them, they don't scare that easily, They'll waddle away from the drone, some times they fly off though. I've had a close call with a flock of geese once. didn't see them coming from the right and all the sudden a big flock came on my screen, I stopped and hovered because it seemed close, probably wasn't that close because the camera makes things closer than they appear but still spooked me a little.
