>>11185239Falcons have fan-shaped tails - all of the feathers are of equal length all the way across, and they spread out fairly wide. Magpies and ravens, however, have wedge-shaped tails - they start off wide and short near the base, but get longer and narrower closer to the tip, similar (but not identical) to what the upgrade kit does.
Incidentally, this is how you can tell a crow apart from a raven or magpie - crows have fan-shaped tails like falcons, while the other two corvid species do not.
