If one of these gets glitches and stuck mid air try to hit it with a flyer. if that doesn't work tranq it and bring a extra flyer and a saddle and have one flyer stay right beside and above the creature then land the first flyer . then grapel to the second one and you can access its inventory and tame it in the air then all you need to do is hurt pit a saddle on it and ride it to have it slowly come down.
