Pronounced "more" as opposed to "mower" it was a native, flightless New Zealand bird.
Now extinct (for a couple of hundred years), the 10 various species were eaten to extinction by the early Maori people.
To give an idea of the size of the moa, picture
the smallest species being the size of a turkey, and the largest being the size of Big Bird from
Sesame Street.
The Moa traditionally lived in
the forest and Moa bones can still be found in caves and swamps throughout New Zealand.
