While flying out along the California Coast yesterday, I had a black oystercatcher attack my drone.
See the following YouTube link for a short video with some frame grabs of the incident:
For a few seconds I thought it was going to go swimming, but it recovered and I was able to bring it back in for a stable landing. While landing the bird continued to make repeated passes at it. Inspecting afterwards I did not note any nicks or damage to the props, only a slight scratch to the side near the bottom of the fuselage. In the future it may be wise to use prop guards when flying along the coast where birds are exhibiting territorial behavior like this may be present. My thinking is that prop guards are more likely to protect the propellers from being disrupted (and thus stable flight) while also reducing the possibility of potential harm to the bird.
