Easiest way we found to knock it out is to use either your best crossbow with tranq arrows or longneck Rifle with tranq darts, having one of your tribe mates carry you on a Ptera or argy. The key here is to always be aiming in the same direction as the person on the bird when shooting, otherwise you may end up shooting the carrying bird with the tranq arrows or darts. This method allows you to get a better vantage and more head shots which are more effective in knocking the animal out.
