The interesting thing is that this is becoming more feasible with modern mirrorless cameras. You can take 4k footage at, say 60P, and at least for larger birds that would be sufficient frame rate, and the resolution would be acceptable.
Inspired by these cool ornitographs, I just made this ornitovideo. As you might guess, it involved rather non-trivial custom post-processing. It was just a first try, I will probably try to finesse it
