Turnagra or piopios and turnagras, is an extinct genus of endemic to New Zealand, both of which are now considered extinct. Sometimes described as New Zealand thrushes, the piopios had only a coincidental, passing resemblance to the Turdidae (thrushes) family. Piopios have been a long-standing taxonomic mystery. They are often said to have more in common with the Ptilonorhynchidae (bowerbirds) family of Australia, but differ in terms of nest construction, egg marking, and voice. A relationship has also suggested with the whistlers (Pachycephalidae). The IOC regarded this family as incertae sedis (of uncertain placement) until the question was resolved whether the genus Turnagra belongs to the Ptilonorhynchidae family. The genus was finally placed in the Oriolidae (Old World orioles) family
