Hey CreigCam, nice to see you over here. PatR is also thinking about getting the Anafi so we might see him here also.
I had the same experience with birds about the same size as the ones flying around in your video. They were circling the Anafi about 20-25 feet higher. I was getting a tad worried but that was about all the did.
Nice video and good use of the 180 gimbal.
