Go to the redwood, look at the trees they'll often fly from one tree to the next. It can take some time to find but when you do they spawn in bunches. Now here's a nifty trick. Not all "grab point" on tree work perfectly, if the archa can't grab the tree it'll just fall vertically to the ground for not only an easy time to tranq it, but also other archas might fall to the ground near the same spot when they come along to feed! I tamed 3 archa in one spot for the price of one (fourth one got away).
Careful about the wildlife especially the angry birds
Alright, so basically I found one of these in the wild and REALLY wanted one. But with all the fun things in the Redwoods willing to take out anything that looks at them... Well you get the idea. But when I went to a dungeon and saw a Eerie one I wanted it SO bad. So I killed that one took its creature implant, revived it at one of the obelisks and tamed that glory bird up. Now I have a light up parachute!
These things make me mad! I've been trying to find a micoraptor to tame for 2 hours now and these guys get my Hope's up. They look identical to the micoraptor, the only difference is that these guys run away from you. I wasted like 25 bolas already !
