Went out to a local parkland today to practice a couple of things, one being timelapse, and out of the blue (literally) I bird dived onto my M2P. I immediately paused it and cancelled the timelapse and reduced altitude hoping to bring it home with both drone and bird unscathed. No sooner that I started to bring the drone back the bird struck again. This happened 3 times and the third time i heard what I'm sure was the props brushing the bird. i stopped the drone and the bird flew into a nearby tree. But when I began moving again it attacked once more. Persistent little bugger if nothing else. I have no idea what variety of bird it was but it's spring here so I assume it is nesting nearby. Is this a common occurrence? I wondered about it from the day I got it and now my wondering wan answered. I'd hate to have injured the thing when all it was trying to do (I think) was protect it's nest.
