Moa

Moa are creatures native to Reach. They are large flightless bird-like creatures that resemble extinct Earth-based Moa. They seem to have feathered bodies and scales from the neck up, leading up to a very lizard-like head.

The Moa are presumed to be edible and consumed by Humans on Reach. The New Alexandria fast food restaurant World Cuisine had an advertisement promoting Moa burgers, priced at 7.77cR. These Moa were most likely domesticated and farmed for food.

Gameplay
The Moa appear as ambient life in Halo: Reach. The Moa are harmless and will not attack the player. They will take shelter under bridges and other formations when there is a battle nearby. Neither human nor Covenant AI are hostile towards the Moa, although if the player kills one while near a member of Noble Team, they will sometimes comment as if an enemy had been killed. The first time that Moa are encountered in Halo: Reach is when several bolt around a corner in an early part of the mission Winter Contingency before contact with the Covenant, causing many players to shoot and kill the birds by accident. They are once again and lastly seen in Nightfall, shortly after fighting the two Guta.

Killing 7|seven of them in the mission Winter Contingency unlocks the achievement KEEP IT CLEAN.

Trivia

 * Moa appear as white dots on your motion tracker, and your reticle does not change color when it is pointed at a Moa. However, if you melee a Moa at close range, it is possible to lunge towards it, as if they were an enemy.
 * The original Moa were a group of flightless bird species native to the north and south islands that make up New Zealand, hunted to extinction between 1300 and 1400 C.E. by the original native Maori tribes. It is unlikely that Reach's "Moa" is related to the New Zealand Moa, and were most likely nicknamed by settlers for their superficial similarity.
 * According to the Halo: Reach Legendary Edition developer commentary, Kat-B320 was originally supposed to laugh when the player kills any Moa due to her reactions towards alien species. It was cut due to the current real-life situation of animal cruelty. However, Army troopers will still comment as if the Moa were a hostile target.
 * It is possible that Moa with the red plumes on their heads are males while the ones without them are females, since the red plumes could serve a purpose similar to Earth's birds, for mating and for courtship, similar to the feathers of a peacock.
 * Curiously, Moa are affected by the Mythic skull.
