This is from one of our comm towers. I was doing some flight training out here as it's nice and wide open. The bird was building a nest and was actually gone when I flew up. It returned and didn't seem overly concerned with the drone. I was flying a M2Z so not as close as the video would make you think I was. Sorry, I didn't do any editing or add any music.
That is an Osprey & you are way too close to it! ! ! Your drone's presence may very well deter it from nesting at the site. We won't know it but it will just fly away & never come back. Then it must find another "safe" place to build its nest while that tower would have been a safe & secure place to raise its young! ! IMHO! (read up on this kind of stuff & don't get so close just because you can !)
