If your level still not enough to make a quetzal platform saddle, you can use paracertherium platform saddle. Place a balista turret on it, and put chain bola in it. Then, when it's chained, tranq it, and build walls around it. Tame it in peace.
An argentavis can't fit through a ceiling with one tile missing, but a pteranadon or lymantria can. Build a trap with one corner ceiling missing, aggro the argentavis, fly in one side and out the missing ceiling tile, and land. Dismount, run around, and close the entry door. Tame safely at your leisure.
