Medium: tōtara, granite base. Size: 19 x 2.5 x 2 inches (incl. base). The Pīwakawaka or Fantail is one of New Zealand's smaller native birds and as its name suggests has tail feathers that splay out in the shape of a fan. This gives the Fantail its distinctive flying style of very short bursts of speed and swift turns with acute accuracy, enabling it to chase and catch the tiniest of insects.
