Common name: Okarito Kiwi
Apteryx owenii – Little Spotted Kiwi
A genetic study found evidence of recurrent hybridisation between Rowi and Little Spotted Kiwi over the last 150 years, including one F1 hybrid found in the last 15 years (Shepherd et al. 2021). Moreover, the syntype of the Great Spotted Kiwi (A. haastii) turned out to be a hybrid between these two species.
