You can eat rare flowers to aggro it, while on your flyer, fly into a 3 or 4 dino gateway trap with pillars or doorways at the end making sure it has a roof, just keep eating flowers while you tranq 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.
