That was painful...
Found Netherbeak finally, but not in the best way. Was flying from Dalaran to the western coast of Azsuna when I bumped into him. I was on autopilot at the time (was looking at the map) when Netherbeak suddenly spawned and killed me within a few shots.
After a found my corpse, I flew back to where I thought I saw him, but couldn't find him for five minutes. He is stealthed, and flies way above the very tall mountain in the middle of Azsuna (the one by Azurewing).
Took me a few tries to get him down to the mountain and to tame him. When I found him the second time around, I lost about a 1/4 of my health from just one hit. After a couple of deaths, I was able to get him down to the nearest piece of land, shot him, turtled-up, then tamed.
