DNA reveals little penguins actually two species: New Zealand, Australian study

New Zealand and Australian scientists have used genetic analysis to identify two new penguin species from what was previously thought to be a single breed.

The little penguins, commonly known as little blue penguins or fairy penguins, found on both sides of the Tasman were not the same species, said researchers from New Zealand's Otago University and Australia's University of Tasmania Tuesday.

"We found a very strong pattern, where New Zealand has its own distinctive genetic group that is clearly very different from the Australian penguin populations," Dr Stefanie Grosser, of Otago, said in a statement.

Like their human counterparts, the two species also seemed to have developed their own "accents," with different calls.

"The recognition of unique penguin species on both sides of the Tasman highlights the importance of managing and conserving them separately," said Grosser.

Another unexpected finding was the discovery that the Australian species - Eudyptula novaehollandiae - was also present in the Otago region, on the southeast of New Zealand's South Island.

"Our genetic data suggest that the Otago and Australian populations are quite closely related," said Grosser.

The team is currently working to better establish the history of the Otago population using ancient DNA.

"The new recognition of endemic species - unique to our region - is crucial for managing our natural heritage," Professor Jon Waters, of Otago, said in the statement. Endit
