I was searching for these guys for the longest time on the island, gave up on it and went about my taming business. Build a trap over the river from my tree base, fly to the local mountain, grab a parasaur and start leading the female giga to my trap. It gets the parasaur, so I grabbed the next closest grabbable creature. An ovis. Now. Really game?! Rip to the sheep that baited the giga the rest of the way through the valley :(
