Save your sanity and build a trap:

2x2 stone foundation

16 stone doorframe

Stand in middle, keep feather stacks at 30+ and wait for yi ling to dive, it'll get stuck on doorframe, throw plant species at head, feed narcotics, repeat...

This tip will show you how to tame a Yi Ling, since I’ve not seen anyone post something like this yet.

So you’ll need the following:

High durability armour

A lot of Plant Species Z fruit

A handful of narcotics or bio toxin

Once you acquire everything you need, head to anywhere near rivers/lakes in the green zone on aberration since they most commonly spawn there, when you find one it would be best to be at a flat surface. You will also need to clear out any other wild Dinos or Yi Ling that you aren’t trying to tame, once you do that you’ll have to let it pelt you with it’s feathers, when you get pelted with around above 30 feathers it will spin in the air then divebomb onto you and you’ll need to time throwing a Plant Species Z fruit at it when it does so.

If you do this successfully then the Yi Ling will become stunned, walk up to it and feed it either narcotics or bio toxin which will increase its torpor bar depending on which of the two you’re using, you’ll have to rinse and repeat this process depending on the level of the Yi Ling until it knocks out. Once unconscious, feed it it’s preferred taming food which is Exceptional Kibble and if you don’t have access to the kibble Raw Mutton will work just as well

I hope this helps anyone in the future for those that are stuck trying to tame one, get to it fellow survivors

Make a 2x2 with stone foundations and 2 rows high of single doorframes all around. Get your feather stacks up to 30 then stand in the middle of the trap. When Yi Ling does the dive it will now be hindered and get stuck for a second or 2 in the doorframe giving way more time to z fruit it. The stacks of feather will not consume because it cant hit you, making the dives more frequent and not waiting again from 1 stack.

Bio toxins work better then narcotics.

A great early/midgame dino (I don't get why people are saying it's a early game rock drake) you will need to get used to the mechanics but what sets it apart from rock drake is it's feathers. Overall it's not good good but it's good for early game

I like this thing, definitely recommend for early game. It can get around pretty quickly, and it can shoot spines from above.

So basically the same as what everyone has put with the trap, but use 4x stone foundations and 24x stone Biotin.

Stand out in the open close to your trap and wait until the feather buff stacks up to 30 and then run inside your trap; the

Yi-Lings glide trail behind it will turn bright red and it will strike at the wall, getting stuck for a few seconds in the process. Throw your plant species z seed at it and then run up to it and feed it Narcotics/Biotoxin.

Here's something, despite dododex saying you can't use a Bola. You can use a bola on the Yi lings. Hope this helps!

There's is a faint red trail that will show up behind it as it circles just before it dives at you. Three bounces and it goes. Throw grenade at top of third bounce

Tank the feathers when it dive bombs you hit it with a y seed and feed it bio toxin after you ko feed extraordinary kibble good luck
