I play on The Island on unofficial. Yesterday, I decided it was time to get our tribe a second Tapejara. Our first one was tamed by a [now inactive] tribe member, and is fairly high-level (in the 90's now, IIRC). So, I get the necessary supplies together: ghillie suit, allosaur kibble, narcotics, tranq darts, bola, etc. Then hop on an argent and start flying around areas where I've seen them previously (north side of the Redwoods, and the forest just to the east).
Well, every time I spotted one, it was either VERY low-level (e.g. 2 to 6), and/or got spooked by some other wild creature and flew off and out of sight before I could even attempt to capture it (I'm looking at you, Level-40!!!).
I caught a couple of them as the day progressed, only to have them killed by wild dinos (a measly dilo in one case, a Rex in the second) before taming was done.
Finally, was able to KO a level 13 in the eastern forest... protected it by building a ring of wooden spike walls all the way around it. And still, a Bronto and a GachaClaus (yes, event's still running on our server) managed to step or crawl over the spike wall! But at least they were harmless, and nothing aggressive bothered us.
So, I got the Tapa fully tamed and led it back to base. Only a level 19 after taming, but at that point, I'll take what I can get!
