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
I see the Otter God, the Jerboa King and the Defender of Bulbdogs made an early move. Now I the Archaeopteryx Lord shall rise. If any one of you guys kill these birbs I will look for you and feed your soul to the ravenous birbs I own. So if you see one my birbs Naruto running away for you, DO NOT kill it instead be its friend, they are a great parachute and they are wholesome creatures to begin with. So you have be warned by the Archaeopteryx Lord...
On mobile these guys tend to glitch out a lot, so try to shoot them when there completely still on a tree. When glitching they often just teleport tree to tree and/or slowly slide down the tree until they fall to the floor (from my experience you cannot hurt or knock them out in this state)
This may seem obvious but if you see an egg TAKE IT! Once taken the female will agro you, knock it out with tranqs and then badaboom it's yours! These guys are a pain in the ass to find and/or tame so taking an egg is probably the easiest way to get em (especially on mobile since they glitch out)
