Aotearoa's extinct birds, heard again at Te Papa

Imagine hearing that sound as the Haast's Eagle swooped down onto its moa prey. From Saturday, that rather scary cry will feature at Te Taiao Nature, Te Papa's new $12 million dollar nature exhibition. And there will also be the sound of a few other birds from New Zealand's long ago past. The designer of the re-creation of the cry of the Haast's Eagle, Piers Gilbertson, is in the Wellington studio.
