You can actually make a good “breeding pen” for these guys if you make a 4 x 3 thatch hut with a generator, one air conditioner, some storage for meat, and bam. The reason for this is because they fit through a doorframe, even with an open door. Good luck
Since the bird nerf, these things are not near as useful. Still, if you get one level up stam and a bit of weight. This is so you can fly across an ocean without running out of stam and dropping into a pool of jellyfish to have your butt hair zapped off.
If one were to tame a low level pteradon, it should be put to use as a travel bird, nothing more, for it is too weak for anything else. However. High level pteradons are excellent for fighting, kibble tamed 100+ can be used to kill alphas, in packs, or alone in niche cases.
