These guys can steal eggs without aggroing surrounding dinos! You can get easy wyvern and rock drake eggs! Put it in a cryo pod, sneak into a nest, pop it out of the pod and have it set to follow close, run to the other side of the nest and when it gets to the nest it will take the egg. Once it has the egg you can take the egg from it and there won't be any aggro. Just make sure you don't switch the egg out of your inventory because you'll get the aggro then. Rinse and repeat for super easy wyvern and rock drake eggs!

Egg-stealing dinosaur was innocent,

THE rare discovery of a fossil embryo has cleared the name of a dinosaur

called “egg stealer”. Oviraptor, first discovered apparently making a meal of

another dinosaur’s eggs, was, it now turns out, simply trying to hatch its own

offspring.

In 1923, an expedition from the American Museum of Natural History in New

York found the first Oviraptor skeleton on a nest of eggs in the Mongolian

desert. The scientists thought the elongated eggs belonged to Protoceratops, a

plant-eating dinosaur whose fossils were common in the area. They chose the

name Oviraptor because they assumed the animal, a predator with sharp claws

and a parrot-like beak, was trying to eat the eggs when it was caught in a

sandstorm and died.

No one could confirm that a Protoceratops had definitely laid the eggs,

however. The contents of fossil eggs are hardly ever preserved. But in the

latest issue of the journal Science, a team of researchers from Mongolia and

the American Museum report on their discovery of a very similar egg containing

a tiny Oviraptor skeleton, almost ready to hatch. The egg was found 300

kilometres from the site of the 1923 excavations.

The 80-million-year-old embryo is the first found from the group of

dinosaurs related most closely to birds. Like birds, dinosaurs brooded their

young, says Mark Norell of the American Museum.

The same nest contained another curious find – the skulls of two tiny young

carnivores belonging to the same family as the velociraptors, best known as

the terrors of Jurassic Park. It is possible that these small carnivores were

raiding the nest. However, Norell says the absence of any other bones suggests

the skulls “were brought to the nest by adult [oviraptors] who had cleaned out

a Velociraptor nest” and like modern ospreys, brought their catch home to

eat

For those who don’t know, this thing is a secret prime meat harvesting GOD! While I’ve been breeding argy for stats and mutations, I tend to get a lot of bad one, so I just kill them. This little guy (who’s making everything lay some more eggs) would run up to the dead body, and attack them. Nothing ever happened, he kept attacking till the body would eventually disappear. One day, the same thing was happening, and I got sick of it, so I grabbed the bird to move it. This thing harvested it. I was shocked. I checked it’s inventory, and it was LOADED! Cooked all of it as fast as I could.

Note that oviraptors do NOT collect the eggs of your (tribe's) tames. Oviraptors are useful because they will collect wild eggs and will allow you to pick them up without aggro-ing any nearby dinos.

To use them, set them to passive and following you/your flyer, drop them near the egg, fly closer to it, then pick your oviraptor up after it snatches the egg. Fly to a safe place (if you're in dangerous territory) to collect the egg!
