Stewart Island shag
(Redirected from Stewart 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.[1] The two resulting species are:[2]
- 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.[3][4]
