Use an itchthyornis to gather fish for it. The buff increases efficiency.

Tried to tame him but I kept dropping the fish instead of feeding him. Between that and him pecking me I got angry, and decided he should taste my sword instead. Sorry dude.

They deal hundred millions of damages to fish... but only does 1 damage to other creatures

ok

The most frustrating thing about taming these guys is not only do they take a lot of fish but the same button to feed them is the same button to drop the fish(i don’t know if it’s different in pc or ps4)and it’s constantly swinging around your face making it annoying because you’re constantly dropping it. Either make it so the controls to feed them are different then dropping it or make ur so it’s not constantly in ur face.

Tame to this kill fish and drag there body to it and once tamed if you feed them more dead fish corpses it will build up and lay a golden egg which is used as a buff to certain dinos or oil or a player buff

Here's how I tamed one using Ichthyornis. 👇

What I did was use my Ichthyornis to Hunt fishes and bring the dead bodies for me.

Change his settings to "Hunt and retrieve", put him on your shoulder then you go swim. While you are swimming aim at The fish you want and double tap F (on PC). Ichthyornis will fly, kill the fish and bring the body to you.

Then you take the body to Hesperornis and feed it. Once you get used to it it's very fast and easy. I recommend following Hesp from behind so you dont need to adjust your aim all the time.

You can do the same to tame Otters.

Feeding them sabertooth salmon seems to work the best.

Don't bother seriously. They are a pain to try and tame. You xan grab a fish 3 times the size of the bird and what's this? 10%!

That's right. Unless you have at least 10 fish all ready to be dragged don't bother.

Could just be a coincidence but I had a MUCH easier time feeding this guy fish while he was swimming in the water than on land. It took a lot of back and forth but he wasn’t constantly pecking me in the face and the dead fish body wasn’t jumping in the way so that feed fish/release body wasn’t interchanging every time. I could barely approach these dudes on land because everything was working against me. I have two parasaur tames stationed parallel the water crossings with their turrets enabled so they can warn me if something nasty heads my way while I’m distracted underwater. Hopefully this helps others out!
