If you're having trouble finding one, get on your bird and go to about halfway up a redwood tree. They like to climb trees and then glide from tree to tree so your chances of finding one in the trees are a lot greater. I found a group of five once in the trees. However, they will glitch when being grabbed from a tree. It might not always be in your birds talons... Anyway, if on the ground, bola it (without scaring it away like a tapejara) and tranq it. It has a low health pool though, so try to watch your arrows.
They are very fast and will only eat chitin. They run away when they see you or you tranq them. Breeding takes chitin too so have lots of chitin. They hide in trees and I have only seen females so Esther males are rare or I’m very bad at finding them
On mobile next to impossible to tame the normal way, I just tamed one by grabbing it from the top of a tree and bringing it very far away from redwoods, then tranq it then tame it. Lots of work, but I love them so it’s worth it.
It’s a lot easier to use a bola when taking than just going for it. One buck with an equus also knocks it out. Make sure to be certain something is a micro raptor before killing it, cause these things are rare and look virtually the same
