Once you get flak or chitin, taming these guys is much easier. Just get close enough to agro them, then bola and use tranq arrows. Kill a dodo or para if you are high enough level, and voila! You've got a raptor. Make sure to either tame more or get an opposite gender. Once you have a new raptor of opposite gender, enable mating and let them do the smoochy smoochies and now you have a raptor pack.
