If u want to avoid long wait times between feeding I suggest trapping the Tropeognathus and then using 1 or 2 regular (not chain) bolas to drop its hunger level as doing this seems to make it lose hunger very fast. Then when u want to tame it place your balista, fire a chain bola at it, pick up the balista again (for future use) and then run up from behind the bolad Tropeognathus and feed it.

A 150 took 35 mins between bolas and kibble feed. Don’t get too close - you need to punch to get away which resets the taming bar. Also only keeping it caught under a ceiling with 2 columns seemed to work. If it can fly up and flee even in a larger trap. taming % plummeted quickly.

Feeding inteverals are actually 20 mins long instead of five. I’m was taming 145 male tropo. On 1x taming. Official server. And after first feeding the next feeding to get to 14 percent take even longer. About an hour. After that comes 20 min feeding intervals. And I used raw mutton.

For taming it’s best to go to an area where you won’t be disturbed often, preferably ontop of a hill or cliff. Make a trap similar to a classic argentavis trap (I highly suggest using mental structures though). On one end you’ll have your gate, as usual, but on the other end have a turret loaded with a chain bola on a metal foundation in such a way that will prevent there being enough space for the tropeo to fly out. Once you lure the tropeo close enough to the trap, run and mount the turret, face it into the trap, and once the tropeo flies in bola it. Quickly close the gate. Be careful walking around the trap, as if it grabs you you’ll have to hit it to get free which will mess up the taming. It’s ready to be fed once it says “doesn’t want to be tamed right now”. You then have to chain bola it again in order to be able to feed it. This is easiest with two people, as it will target whoever last chained it, allowing the other person to safely feed it.

If they are high in the sky use a quetzal with a ballista on its platform saddle. Chain bola it and use a wing suit to follow it down. Place stone dino gates over the tropeo and block the two ends with doors. Make sure to leave a gap between the dino gates that is wide enough to shoot a chain bola through. Then proceed to tame it by shooting it with another chain bola and feeding it exceptional kibble. I solo tamed one this way but more people would make this method easier. Tip: If you do this solo have your quetzal on follow and passive.
