To get fertilized eggs, they must be on wandering in water. They wouldnt mate onland, only when I put them in water. Just attach them to a hitching post in the water.
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.

Player-written tips for taming, using, and fighting the Hesperornis in ARK: Survival Ascended & Evolved.
I find them mostly in small or pond size bodies of water . They generally spawn in the lake that connects to the swamp closest to the red avilus
Easy taming trap that helped me, got four back to back. 1 foundation, 4 window walls. Place foundation down and two walls up, hit hesperornis let it agro on you and lead it to foundation and trap it in with the remaining two window walls. Fed (through open window slot) it…
Easy taming trap that helped me, got four back to back. 1 foundation, 4 window walls. Place foundation down and two walls up, hit hesperornis let it agro on you and lead it to foundation and trap it in with the remaining two window walls. Fed (through open window slot) it sabertooth salmon 1.0 and higher for faster tame.
I’m guessing these things aren’t on mobile which is a shame because I really wanted one.
add hesperornis to mobile spread the word
Unlike most small creatures aside from small carnivores, hesperonis will aggro if you punch them.....
Breeding seems to take about 28 hours.3.5hr egg 3hr baby.
These ducks spawn in small lakes or pond size bodies of water . I always find two or three in the lake that connects with the swamp on the southside of the map closest to the red avilus . Also beware of titanboa coming from hills and sarcos going into water . I suggest you take…

Taming tip: tame a male and female 150 giga, mate them, then trade the eggs for level 20 hesperonis.
Worst. Tame. Ever.
At least on Xbox, pressing Y to feed is near impossible, especially with a large fish. And if you are trying to tame it on land, and miss the feed with Y…

Worst. Tame. Ever.
At least on Xbox, pressing Y to feed is near impossible, especially with a large fish. And if you are trying to tame it on land, and miss the feed with Y and drop the fish it will either A) be eaten by the hesp and give you no credit, or B) float into the air and not allow you to grab it again, even when targeting.
Solo taming a 145 spino and tried a 45 hesp while witing. Spino is almost done and I finally gave up after 3 salmon in a row floated away into orbit.
How to feed golden egg to Dilo on Ark mobile. This hesperornis has been a huge headache and my golden egg is about to spoil.
Basically they will attack you but aren’t very dangerous just make sure they don’t come by 10 or yeah… You might loose a lvl 200 Raptor 🥲🥲
These give small amount of polymer. Instead of hunting these go look up Penguin spawns.
Make sure to clear the area because they are pretty low health and do 1 damage to other creatures
Taming a high level is painstakingly slow, especially if her mate is lurking around. Only .5 to 2.0 % for a SALMON! I would rather poke my eyes with ice picks than tame another one. But seriously make a 1 foundation with 4 walls trap with ramps on both sides. Make sure you put…
Taming a high level is painstakingly slow, especially if her mate is lurking around. Only .5 to 2.0 % for a SALMON! I would rather poke my eyes with ice picks than tame another one. But seriously make a 1 foundation with 4 walls trap with ramps on both sides. Make sure you put a ladder in side as you will need to get out after you fed it. DO NOT use a door and doorframe as you may mistakenly open the door when trying to feed it and it can get out. Aggro the bird and lead it up and into the trap.
If you ever see this big duck, kill it and eat it’s natural polymer that will make you immortal for one minute
We had a raft with walls all around it and the entrance was a door with some stairs so we ran into it with the door open and it went right in, then we just took turns bringing it fish, it took about 30 minutes and only escaped once.
Why do we need these it’s just doesn’t make sence
Must tame for the switch. Make those kentro kibbles to tame yuty with their golden eggs. 25 fish for it to lay a golden egg. Count it out, then toss on land.
Is this in ark mobile update for no
I haven't encountered these yet and this is just a maybe but i think maybe you could use a pteranodon or some other flyer that can pick up animals, you can make a 1x1 hut without a roof and drop it there, and make it be right next to a water source with fish to make the…
I haven't encountered these yet and this is just a maybe but i think maybe you could use a pteranodon or some other flyer that can pick up animals, you can make a 1x1 hut without a roof and drop it there, and make it be right next to a water source with fish to make the process quicker. If the water source is shallow enough you could use something like a trike or a baryonyx to insta-kill a bunch of fish, and I'd probably recommend saber-tooth salmon since coelocanths give too little taming effectiveness and i don't think piranhas are worth the hassle.
Like i said, all of this is a big maybe, and maybe it doesn't work
It killed me when I tried to get my stuff because I died next to a Spino and I did not know if it attacked and it did over 57
