For the love of god tame these on double xp and only tame low lvls

They must be able to float in water to lay eggs.

Be prepared to sit and tame for a very long time. They use up a lot of narcotics so you don't have much time to look away from the inventory

Use a quetzal to take it to a safer location. Tranq it with darts and bring an appropriate amount of narcotics. Torpor drops as fast as a Giga

Amount of narcs used is not correct, a lot more was required.
