I hate these so much. I used to have this pond near my base. Id tame coelacanth and piranhas and have them hang out there. One spawned and killed every single one of them. I hate these. Kill them all. You should, either way. You could get all that organic polymer.

Kill them. All. Make them extinct.

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!

Ive seen people say these guys only agro on you if you hit them, but whenever i go near these guys they agro on me.

I picked it up with a grappling hook, then jumped on my wyvern & flew it to a safer place to tame with lots of salmon. I also threw a tent over it to stop it from wandering off. Best way to tame. So much easier.

To harvest organic polymer at a maximum use a club

One of the worst things you need to tame for kibble, but this is how to do it:

1. Craft a wooden cage

2. Aggro it onto land

3. Place cage on top of it

4. Spend an hour killing fish and dragging them to it, feeding it through the bars carefully or you’ll open the cage and let it out.

5. You let it out, didn’t you? Pick the cage up and trap it again.

6. Watch out for that ichth- It stoke your fish... and half the stuff in your inventory. Kill it.

7. Cuss in frustration at every piranha on the Ark trying to eat you, then feed them to it too.

8. Finally finish taming the dumb bird - now just remember to keep feeding it fish forever.

Oh and watch out for Argentavis in the area, they like corpses and they don’t like you even if you’re carrying the corpse. They’ll steal your fish and then try to kill you.

Easiest and stupid just kill a fish trow it on land near it, it will go for it, bigger fish means he eat for longer, then just lock the bird in a closure or tent if the trick works (did not try it yet), if you want to make it easier trow window on the wall and it should be ok to feed.

Though most people think of the Kairuku when it comes to Organic Polymer, Hesperornis also drops some, which makes it valuable to early-mid game players who don’t want to risk heading north. As with Pingu, club it when dead to obtain more polymer.

Put it in a taming box these birds are an easy kill for predators

Why is there no breeding data on here?........ you can breed them and have babies and have a whole farm if you like to get O.Polymer .....

These creatures are great for early players as they are a good source of oil (That I use to make grenades and destroy my enemy) and to get the oils you grab it's egg and throw it in a cooking pot and there you go, go make grenades and ruin your neibours stone base :D

Needed some hide and thought this was a dodo and was surprised when it Agrod on me

Very common, I spotted 2 on my second day, they don’t attack unless u attack first (from my experiences)

A way to tell if your tamed hesperornis is ready to lay an egg is if it is wandering, even though you didn't turn wandering on the hesperornis.

You can look at the creature window and if it says "enable wandering or mating to mate", then it needs to harvest a few more coels or salmons until it can lay an egg.

If it is ready to lay an egg, the window will say "ready to mate", which is really helpful if you haven't been keeping track of how many fishes it has harvested.

It will also automatically turn wandering on to allow the hesperornis to pathfind to land.

Apparently the taming for this bird is bugged in Ascended because I've been teying to tame a lvl 90 female for hours now. Can't drag the fish corpse to it. It won't let me feed it. I've even tried taming it with fish meat. Has not worked at all.

On the islands hidden lake there’s always a few of them. Not only are their eggs good food but every now and then they’ll give you a golden egg. Perfect for leveling if you plant a base at hidden lake. Not to mention they keep that lake clear of piranhas for you! Don’t need to tame just grab the eggs

You can’t pick wild ones up with Creatures. Luckily these animals will attack you and chase you if you go right up to them.

I used this to a create a Box with 1 foundation, 3 walls and a door. Got the Hespornis to chase me into said box where I locked it inside. After that it was a simple case of getting my Icthyornis to hunt and retrieve fish for me then feeding it to the trapped Hespornis. It still took a long time. But at least i didn’t have to chase the Hespero or press Y to feed then drop the fish

Place a cage and punch it. Leave cage open and punch it go on the side that the cage is open and it will walk in and close it then place sign. You can then open it and feed it without it being able to leave. Saber & piranha is the best. Side note seemed the faster I would feed it the more it went up in taming. (Did not look at the size of the fish.

It has a High spawn around south zone. So it would be recommended taming them there

"Eat the lumpy mashed potatoes you get from killing it. It's good for you."
