Nah'qi <Ember of Regrowth>

Located in Amirdrassil, The Emerald Dream. Nah'qi flies counterclockwise around Amirdrassil, but very high up, just below the tree's canopy. She isn't flagged as a rare, so you won't see a rare marker on your map. Taming this unique owl requires a special skill which is taught by the Cinder of Companionship. The Cinder is awarded when you learn the mount item Reins of Anu'relos, Flame's Guidance which is a rare drop from Mythic Fyrakk in the Amirdrassil raid. Using the Cinder creates an account-wide unlock for you to tame Nah'qi, so you don't have to specifically obtain it on your hunter.
