Strigops habroptilus Gray, 1845 is the valid scientific name of the kākāpō (Aves, Strigopidae)

The kākāpō was named Strigops habroptilus by G.R. Gray in 1845. However, in recent decades authorities have begun to recommend habroptila as the correct species name through mistaken interpretation of gender agreement rules. Here, we explain that habroptilus remains the valid species name through correct application of the articles in the International Code of Zoological Nomenclature.
