Vulture

Vultures are carrion birds that can be found throughout the drier areas of Kalimdor — seeking carnage upon which to feed. The mottled scavengers have been known to aid the vile harpies from time to time — drawn by the promise of freshly slain flesh and blood.^[1] They have also been seen in Outland, but with two heads.

Boulderfist clan legend recounts a cloud of carrion birds following ogre warriors through the Dark Portal during the Second War; it may be that all two-headed scavengers in Azeroth are their descendants.^[2]

Mulgore swoops are often hunted for their quills by the tauren.^[3]
