OS was on. It was "1" mode and I'm not sure whether in that case I should have set the "2" mode (the one which supports panning). Indeed the bird was zig-zagging, but I wasn't panning, strictly speaking.
All the firmware at the latest update. 562mm is because I placed the ring midway between 500mm and 600mm (and it turned out to be 562mm). The reason is that on one side I wanted the max. focal length, 600mm, but I can preliminary confirm (even though I didn't run specific tests yet) that the sharpness of the lens degrades faster when it approaches the long end, as some reviewers said; so I think it's better to give up to a few millimetres and get somewhat better sharpness.
