Tip1) Raptors usually spawn next to the rivers and sea shores but watch out for spinos,Sarcos,and therozinos,

Tip2) You don’t really need tranq arrows although they make it easiest to knock out. What you need are a lone raptor spyglass (optional) bolas about three and raw meat about 40 for the mid levels. You also need narcotics and about 20 but you could just bring 15. And finally a slingshot and the shots have to be aimed at the head for best knocking out effect. Hope my tip helped and if there are more than one your best bet is try to kill a few using pikes.
