I saw some comments said that it's really hard to tame(ko), but actually it's not. Just fly straight to it and consume flowers and make it attack you(damage is pretty low, no worry at all), and then lure it in to your pen(better build it bigger to have a greater chance to trap it), close the gate, and then take your time taming it
ARRRRRRRGH I just had THE WORST taming experience! Pro tip: DON'T try taming a high level one by dangling from an argy by a grappling hook... You'll end up dying TWICE and losing your argy, guns, and 80 narcotics... >:( :(
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.
