Found on Abb and Valguero. I find them easy to tame on Valguero since they can be found outside radiation zone there. Do yourself a favor and farm Plant Species Z seed on Abb and tame them on the weekends during 2x taming events (official servers). They fly around a LOT, the Z seed makes it a quick tame. They don’t flee if you don’t hurt them (tried crouching and it was worse than standing).
The cave where the artifact of the stalker is, is full of them. Quite easy to find high levels there instead of walking around on the red zone area. Cave entrance is at 81.4 48.2. Come with a good rock drake to make the thing easier. The best part of the cave is that, unless on got attacked they don’t move so you just have to feed them. Hazard suit is necessary
