Some close calls in there, but also many of the birds interactions made the scenes even better.
For many drone pilots, birds in the area acting aggressively is reason to leave the vicinity and try somewhere else nearby.
Birds mostly see a drone as a potential predator, or with other birds of prey, a potential invader (territorial birds).
Breeding and nesting season generally makes many species much more aggressive, even so far as to striking the drone.
Obviously bad to the drone (props break easily) and the bird !
Most say the best course of action is not to fly straight away horizontally and / or descend, as birds can often keep up, but going straight up in a vertical climb is best, then fly to home and descend asap.
All birds are slower to climb of course, so this gets you out of the danger zone quickly.
I've only ever been buzzed by a Peregrine Falcon, had to slow the video down a lot to even see it in most clips . . . in the end I decided to bail out, going straight up, and I left it circling below and flew to home point up high.
I hope safe flights continue for you.
