The Hesperornis (hess-per-or-niss) is one of the Creatures in ARK: Survival Evolved.
Basic Info
Dossier
This section is intended to be an exact copy of what the survivor Helena Walker, the author of the dossiers, has written. There may be some discrepancies between this text and the in-game creature.
- Wild
Possessing the appearance of a half-duck/half-dinosaur, Hesperornis is a medium-sized, fish-eating bird, common in the rivers and lakes of the island. It would be about two-thirds the height of a human if it stood tall, but it rarely does. Hesperornis spends most of its time gliding along the surface of the water, where it is much more maneuverable. Hesperornis is barely a threat to any land-dwelling creature, as its legs are too short for it to move around effectively, but it is surprisingly fast in the water. It can easily hunt down fish and other small water-dwelling creatures.
- Domesticated
Not particularly useful for hunting, and not being affectionate, Hesperornis is primarily kept for the eggs it produces after consuming much fish. When rendered correctly, the eggs separate into two useful substances. One is a protein substance that is high in calories, and the other is an oily liquid that is effectively the same as the Oil found in the ocean!
Behavior
Hesperornis is quite content to ignore animals and survivor, unless if they get too close for comfort. They will bite any player that touches them before fleeing. They devour fish such as Coelacanths and are in turn hunted by predators and survivors who seek their organic polymer.
Appearance
The Hesperornis is a strange bird resembling a dinosaur mixed with a loon. Like a loon, it has a long neck, waterproof feathers, and strong webbed feet that propel it through the water at the cost of being rather helpless on dry land. Unlike a loon, it has vestigial wings that prevent it from flying, as well as small needle-like teeth to snatch fish - its favourite meal.
This section displays the Hesperornis's natural colors and regions. For demonstration, the regions below are colored red over an albino Hesperornis. The colored squares shown underneath each region's description are the colors that the Hesperornis will randomly spawn with to provide an overall range of its natural color scheme. Hover your cursor over a color to display its name and ID.
This information can be used to alter the Hesperornis's regions by entering cheat SetTargetDinoColor <ColorRegion> <ColorID> in the cheat console. For instance, cheat SetTargetDinoColor 0 6 would color the Hesperornis's "main body" magenta.

Wild Stats Level-up
Type in values of a wild creature to see on which stats it's emphasized. Green values on a high-level creature are very good for breeding. If you have already tamed your creature you can try to recover the breeding stats with an external tool.[1]
The stat-calculator does not work in the mobile-view, see here for alternatives: Apps
Note that after the creature is tamed it gets bonuses on some stats depending on the taming effectiveness. This makes it hard to retrieve the levels on a tamed creature, so this tool is only for wild ones, but gives a first impression, how well the stats are distributed.
Taming
This bird uses an odd version of passive taming. You must kill fish and then bring it to the Hesperornis to tame it. It appears type of fish and, most importantly, size affects how quickly it's tamed. A small fish might give 2-3% taming progress, while a large one can give 9-10% or more. There is a 30-second cooldown between feedings.
A good strategy to use is to put a fish in a foundation with a ramp and three railings, with one open side towards the birds. Then, they'll walk into it without any effort. Another method is to use a 
Grappling Hook to drag them to your pen.
Salmon seems to be more effective in taming than Coel. Taming it with fish obtained by an Ichthyornis gives more taming percentage.
The Hesperornis deals 0 damage with its attack, so getting it to attack you which prevents it from running away is a good idea. Luring it into a pen by walking near and gaining its attention is the best way to prevent you from losing it while finding more fish.
Using an Icthyornis to kill fish will drastically improve taming effectiveness (roughly 5 to 10 times greater effectiveness per fish) due to the "prime buff" given by fish it kills.
Note that this creature was recently released, so official taming data is not yet available.
The information presented here is based on anecdotal evidence and may not be entirely accurate.
For a level-dependent count of time and resources needed, try an external taming calculator, but keep in mind that their numbers are also unofficial.
Combat
This section describes how to fight against the Hesperornis.
General
Strategy
The Hesperornis is very slow and poses very little threat, so using a pike should easily do the trick.
Weaponry
Dangers
The Hesperornis poses essentially no dangers to even a low-level survivor. Care should be taken while hunting or taming them however, as their preferred hunting areas are rivers, often teeming with other dangerous creatures. Most notably, the piranha, which will occasionally try to grab them from the surface of the water.
Weakness
They are slow runners, meaning you can easily out run it, or hit it with a weapon and run before you get hit yourself, they also have low health.
Utility
Roles
Egg farm: Hesperornis can lay Golden Hesperonis Eggs and Hesperornis Eggs after killing and eating 25 fish. The Golden eggs give a temporary 500% experience boost to smaller creatures such as Dilophosaurs, Troodon and Compies or a 10% boost to larger creatures when consumed. They are also an ingredient in Kentrosaurus kibble used to tame Yutyrannus. The normal Hesperornis Egg can also be placed in a cooking pot to produce Oil.
Polymer: These animals are a great way to obtain Organic Polymer for people who do not have Fur Armor or who are far from the snow biome .

Notes/Trivia
For information pertaining specifically to the real-world Hesperornis, see the relevant Wikipedia article.
- The dossier was revealed on 08/21/15 [2]
- Like Archaeopteryx, Hesperornis was a proto-bird, meaning it still retained some Dinosaurian features, such as teeth and visible fingers, which most modern birds lack.
- In real life, Hesperornis was native to the shores of shallow shelf seas like the Western Interior Seaway and acted as an easy prey for ocean predators like Xiphactinus, Tylosaurus and Mosasaurus.
