Insular species are particularly vulnerable due to their limited habitat and range. Extinct ratites include the moas of New Zealand and the elephant bird of Madagascar. Today, many ratite species are vulnerable or near-threatened and are protected. Hopefully, the measures taken will lead to stabiliz...
