Halo: Reach

Moa are the birds that look just like ostriches. They are two legged creatures that you first encounter on the second mission, "Winter Contingency". You must kill them with bullets. If they are killed by AI fire or grenades. It will not count.

Thanks to Sidedish120 over at x360a for the description.

You should load up the mission 'Winter Contingency'.

The next step is to look out for the ostrich type creatures in this area, they are quite fast so if you are not confident enough shooting fast moving objects i would select the 'MA37 Assault Rifle' and just spray in their direction.

After landing and walking past the initial checkpoint, 2 of them should spawn ahead of you as you are walking to the edge of the cliff. Get ready to shoot :)

The next lot that can be found are after crossing the river from the first firefight, I found if you go to the right of the river and stand at the start of the bridge, switch to your magnum and zoom in on them in the distance. This way they don't run off from the sight of you and they are easier to kill.

After the second firefight, jump down the cliff side and be prepared for the next lot of Moa. I counted 4 or 5 here so this should get you the achievement. They run quite fast away from you so if you move slowly until you see them and use the same method as before with your magnum.

Hope this Helps :)

You have to kill 7 of the tall birds on 'Winter Contingency'. mission, it has to be a at least on normal difficulty and done all in one life, dying resets the counter.

You will need to kill 7 of the weird ostrich type animals in the 2nd mission "Winter Contingency". These will need to be weapon kills as vehicle kills do not count. You also have to do this on normal difficulty or harder.

Hooray for Achievement Hunters!!

Geoff and Jack show us how to get this achievement in halo reach. A Moa is native bird to the Planet REACH(it looks like a ostrich here on Earth). You have to kill them with your battle rifle,pistol or melee them. Remember vehicle splatters do not count and you need the grand total is 7 of them.

Enjoy!

(before you give me a "thumbs down" on this or any other solution. Tell what I can do to fix it)

As it says, you indeed have to shoot 7 Moas (ostrich-like creatures) down, but without dying. When you die, your progress is reverted to zero.
