When taming a bird u always want to check the lvl. Using a crossbow and tranq arrows, if the bird is lvl 1-15 u won’t need a bola. Shoot it in the back and it should get knocked out immediately. If the bird is lvl 15-higher then u might need a bola, shoot it in the head. Wait about 15 mins while keeping its unconscious lvl up, then after starving it feed it any kind of meat or kibble and it will tame very quickly.
