No, this isn’t a tip…. But I just got done taming one of these…. and it felt like I was in passionate of the Christ. I’m on Xbox a.k.a. Xbox controller.. this was a really torturous experience.
Hesperornis
Hesperornis is a fish-hunting waterbird prized for its valuable eggs: regular eggs can yield oil, while golden eggs are used to make Extraordinary Kibble.

How ARK players tame and knock out the Hesperornis: what to feed it, what to knock it out with, and how to keep it safe.
If you tame one it’s useless so just kill it
