Oviraptor

Player-written tips for taming, using, and fighting the Oviraptor in ARK: Survival Ascended & Evolved.
Egg buff don’t affect scorpions. (Immensely disappointed, I got the ovirator for the sole reason of buffing my pulmonos, tryna get kibble for rex, turns out all a wasted effort)
I wish I could tame it with something a little easier to get…
Bola them there fast and sneaky
You can bring it in a cryopod to wyverns nests and have it follow over nest to steal eggs with no agro
You can over burdened your Oviraptor and set it on wandering and he will still give off the buff.
It can steal eggs without aggro animals but you being there will. Tricky but can be done.
In ASA they Now spawn on aberration, in the green Zone. I found mine near the ancient device
This creatures ability is to steal eggs without alerting their parents however this ability only works when he is in the nest and set to follow you so use this to your advantage and steal things such as wyvern eggs

It is easy if you have an bronto to lay the eggs, because you are just going to have more eggs after taming him/her.
Oviraptors DO consume both regular and fert eggs in feeding trough. Confirmed by adding dodo eggs and he consumed immediately
Set it on wander and fill it with stones so it's encumbered, then you don't have to pen it
I love these guys they steal eggs for you and they are cute I was once out with my oviraptor and I saw a bronco egg so I stole it and it’s hilarious to look at him with the bro to egg
Took like2 trans darts and a quetz egg
You can find them near the open plains near Volcano on the island. Its from the cave, up the hill, away from the river. There will be some jungle, then you'll hit a wide open plains area. Careful. Carnos spawn there very often as well.
Had trouble getting it to pick up egg then reached down and picked up a bronco egg in its mouth! Bronto did not even notice! So amazing screen shorted it.
It's actually very easy to tame in the beginning, just steal bronto eggs and run away then come back when they're not aggressive anymore, then easily tame oviraptors!
Do NOT use Carch eggs. They tank effectiveness and don’t give much taming progress. They are not equal to Giga eggs.
If you see a oviraptor you might sometimes see it steal eggs
Just make a small pen with fence foundations and windows, pick one up with an argie, drop it in and tranq it and tame it at your leisure.
