Faʻahia

Because much of the site is waterlogged, artefacts made of organic materials have been well preserved, including wooden patu hand clubs, canoe parts and adze handles.

Subfossil bird bones have also been well preserved, providing much new information about the avifauna of the island around the time it was first settled by humans, demonstrating that even small islands could hold a rich variety of bird species.

The remains of several species of birds have been found, representing those that were killed for their flesh, bones or feathers by prehistoric Polynesians.

Locally extinct land birds found were striated heron, spotless crake, Polynesian ground dove, Marquesan imperial pigeon, Polynesian imperial pigeon, and Tahiti reed warbler.

The only globally extinct seabird was the Huahine gull, but several other seabirds that are now locally extinct, at least as breeders, were found, including the wedge-tailed shearwater, Christmas shearwater, Audubon's shearwater, Tahiti petrel, Phoenix petrel, Trindade petrel, brown booby, red-footed booby, great frigatebird, lesser frigatebird, and black noddy.
