What is "puaiohi"

The puaiohi or small Kauai thrush (Myadestes palmeri) is a rare species of songbird in the thrush family, Turdidae, that is endemic to the Hawaiian island of Kauai. It is closely related to the other four endemic Hawaiian thrushes, the kāmao, olomao, ōmao, and āmaui. It was first collected by Henry Palmer in 1891 at Halemanu around the entrance to the Kōkee State Park.
