- if you bring other tames with you to find one of these, leave them a ways away, as their presence may scare the sinos

- they won't notice you unless you're within less than 40 meters, at least from my experience

- once it notices you, stop moving or else you might spook it. wait for it to come to you

- track it with the taming hud. trust me, it can be tough to follow without it

- if you hit them or they take some other damage while taming, taming percentage goes back to zero

good luck!
