Passive tame. Approach the unmounted creature and feed it from your last inventory slot — no knockout needed. Set a quantity on any row to plan a mix; higher-affinity foods keep effectiveness up, so feed those first.

Forward calculator. Enter the wild points a creature rolled (and domesticated points you spend after taming) to get each stat's value. Uses official-server rates with no imprint bonus. Melee and movement speed are shown as a percentage; taming effectiveness only boosts stats with a taming bonus (such as melee).

Raising. The Baby phase (0–10%) is the dangerous window — the baby can't eat from a feeding trough and must be hand-fed until it reaches Juvenile. Imprint at each cuddle interval for the full bonus. Wall-clock times assume the egg is fertilized now and rescale with your server profile; mating cooldown is unaffected. Imprint counts assume the default imprint amount — tune that on the imprint calculator.

Hesperornis guide

The Hesperornis is a carnivore in ARK: Survival Ascended. It spawns wild on The Island and Extinction. This page covers its spawn commands, base stats, taming and breeding — with interactive calculators you can drive by level.

How to tame the Hesperornis

The Hesperornis is a passive tame — no knockout needed. Approach it carefully without weapons drawn and feed it raw meat — with raw prime meat, cooked meat or its preferred kibble taming faster and keeping effectiveness higher from your last inventory slot, waiting for the feeding cooldown between each. Staying out of its line of sight and avoiding sudden moves stops it fleeing or turning hostile.

Hesperornis spawn command

To spawn a wild Hesperornis, open the console and run its Summon command. To spawn one already tamed at a chosen level, use GMSummon instead — both are copy-ready in the Spawn commands panel above, along with the raw spawn class (Hesperornis_Character_BP_C) for use with commands like SpawnDino.

Breeding the Hesperornis

The Hesperornis can be bred. Fertilized eggs must be incubated at the right temperature before they hatch. Use the breeding calculator above to plan mating cooldowns, incubation or gestation time, and the maturation timeline from baby to adult, including the imprinting schedule.
