If you wish to find go to winters mouth, face the icebergs and head left around the beach. From the first icebergs to the ones you see after going around the beach, and a ways up the mountain. Not Ovis city but I got four in an hour. Never could find a female. I hope you have better luck than.
The frist time I saw mine, I was on the edge of the redwood forest near a small stream. I picked it up with my Argent, so if you want to take it home and save it for breeding or tame meat that's the way too go.
I find a lot of them near 70,90 on valguero. It looks like it would be the chalk hills biome but it actually says it’s the jungle biome. And when you tame it don’t forget to feed it berries. Happy Hunting!
