Dododex
ARK: Survival Evolved & Ascended Companion
Tips & Strategies

These birds make a very good tame for a variety of reasons:
Firstly, as combat pets: working similar to a dimorphodon but underwater, capable of taking down even the largest creatures in a swarm, and also being able to wear hats for extra protection.
Secondly, as egg animals: their egg is as light as a dodo egg but slightly better food, and they're much easier to find than dodos in the snow.
Thirdly, as heating: they are brilliantly insulated to the point that they actually overheat even in their snowy home and radiate warmth, useful for keeping warm or hatching eggs.
Fourthly, as companions: they make good pets due to their appearance and ability to wear various hats

Perhaps i belong on a war crimes list for this, but i have a male and female of these with breeding enabled in a building with a dimetrodon set to aggressive, the dimetrodon hatches the eggs with enough melee stat and then eats the hatched babies for an infinite polymer farm
Their sole purpose is to be killed for organic polymer, but you can tame and breed them for it:
Tame a whole bunch of them (you only need one male), and a dimetrodon and pelagornis.
Level the dimetrodon's melee damage a whole bunch and put it in a cage surrounded by penguins set to mating. Put the pelagornis in with them at set it to aggressive, the dimetrodon will incubate the penguin eggs and the pelagornis will immediately kill them when they hatch, free organic polymer factory.
