NZ has the most flightless birds

Isolated from mammals, New Zealand birds developed flightlessness and filled niches taken up by mammals in the rest of the world. New Zealand is spending tens of millions of dollars to create pest-free sanctuaries and prevent the extinction of these strange birds. New Zealand’s remaining flightless birds include five ratites (kiwi), one parrot (kakapo), two rails (takahe & weka), two teal (Auckland Island teal & Campbell Island teal) and six penguin (blue, erect-crested, Fiordland, rockhopper, Snares and yellow-eyed).
