The Great Spotted Kiwi or Roa (Apteryx haastii) is the largest kiwi species in New Zealand. It is endemic but threatened with populations only in the north of the South Island.
One may recognise the roa by its ashy and grey feathers that are banded horizontally containing small white spots. These birds can grow up to half a meter tall, are flightless and mostly active at night. They feed on small insects including spiders, snails and cicadas as well as fallen fruits.
16,000 birds are considered to exist with over 50% in northwest Nelson. Dogs and introduced stoats threaten the species since kiwis only breed one egg at once.
