Stewart Island shag

Stewart Island shag or Stewart shag was the former name of a species of cormorant that was split into two species as a result of genetic studies. The two resulting species are:


 * Otago shag, Leucocarbo chalconotus, which is endemic to coastal Otago, New Zealand
 * Foveaux shag, Leucocarbo stewarti, which is endemic to Stewart Island/Rakiura and Foveaux Strait in New Zealand

Some authorities, such as BirdLife and the International Union for Conservation of Nature, continue to treat these as a single species.
