What we actually know

Yes, for the big ones. Moa were real birds that lived only in New Zealand: nine species, none of which could fly. The biggest, the South Island giant moa, stood up to about 2 metres high at the back (about the height of a door) and could weigh around 250 kg. Not every moa was big: the little bush moa, the smallest and most widespread, was about the size of a turkey. So the claim is true of the giants, not of every moa.

Nobody alive today has seen a moa. They died out soon after people arrived in Aotearoa, mainly from hunting, along with the burning of their forests. The last ones died about 600 years ago. What we know comes from what they left behind: bones from caves, swamps and sand dunes, eggs, feathers, and footprints pressed into old riverbed mud. In the summer of 1935, gales shifted big sand dunes at Doubtless Bay in Northland and uncovered the bones of several kinds of moa. That's the Wind's story in the round.

The round's real subject is witnesses that aren't people. Kea's reason is true (nobody alive has seen one), but it doesn't settle the claim. Things nobody alive saw can still leave a record behind.

You may read that the giant moa stood 3.6 metres tall. That figure is a length or a neck-stretched height, and how moa held their necks is debated, so the round uses the 2-metre back height only.

What kids usually bring

At dinner

Ask: "How can we know about something nobody alive has ever seen?" If you're near a museum with a moa (Te Papa, Canterbury Museum, Otago Museum, Auckland Museum and many smaller ones have them), go and stand next to one together. Who's taller? Look at its back, not just its head.

Then the one rule: say their reason back before you give yours.


The round never tells your child what to think. This card tells you what we know, so you're never caught out. If your child wants to argue with it, that is the point.
