All these Ghillie tips are nice but all you need to really do is bring rare flowers. Make sure you're on a Ptera and there aren't any Pteras around. Then just keep eating the flowers and lure the Tapajara to your base or a safe spot, green obelisk is best as there is little to no threat besides people's auto turrets and they're most commonly found at green obelisk.
Extremely difficult to tame. Best options are to bola it, and then use a longneck rifle with tranq darts. Otherwise trying to get it to fly into the side of a cliff and get stuff is the other option for a solo tame.
Since the new update, rare flowers make dinos aggro on to you, you can use this on a tapejara and it will follow you to a trap you've built. Just remember that each flower gives only 10 seconds of that debuff so if the bird is far away from your trap, you have to use it frequently while coming back. Also, if you need it to follow you after you've gotten off your dino, you need to eat another rare flower so that it can agro on to you once again.
