If you have a Tribe, a Quetz or Ghille Armor Tapejara is an easy tame. Ghille allows you to go up and sniff it, Quetz allows you to use a 3x3 trap and with a Tribe of 3-5 just get everyone to headshot it with tranqs and a level 60 or lower should drop before it lifts off. Obviously higher tier Torpor projectiles allow this to work on higher levels.
If you have none if that, it is still doable. All you need is a Bola and anything that inflicts Torpor. Crouch walk behind it until you get into the range where it'd see you if you were standing. Start swinging the Bola and stand up and walk towards it. You've got about a further second to close the gap while it taunts before flying. Aim a little over its head as Bola drops fast. And try to throw it dead centre as it seems to be just go throw wings.
