Easy solo tame! Get on a flying mount with high health. Tapejara usually have low meele damage but I go with high health flyer in case. Couple thousand health And over 1000 stamina.
What you do is put 100 rare blue flowers in your hot bar ( or more depending on how far you have to lure it ). When you see the tepejara fly up to it and eat a good amount of rare blue flowers. Keep an eye on the timer. Don't let it go out or it will fly away. The tepejara will attack you and you just need to get to the ground in a safe area. rememeber everything else will attack on ground. I usually fly to my taming pen and land in it so nothing can get inside. Get off your mount and BOLA the tepejara while it's attacking your flyer ( remember passive mode !) Then tranq darts or arrow. Darts are better less damage, it only take a few. Don't worry if it's a low level, tepejaras level up fast. I tame them solo constantly this way. Never had help one time with a tapejara tame. Happy taming :)
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.
