Don't like getting titanoba eggs your self drop this little dude in the swamp and follow it with a argy or quetzal and when it manages to get a egg swoop it up and you got your self a titanoba egg with out any harm done to you
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!
I've noticed that oviraptors tend to glitch out of pens and Dino gates. So I started loading wood til they can't move. Won't help if your trying to get a fertilized egg but will allow there bonus egg production to work without losing them.
