The Great Spotted Kiwi or Roa (Apteryx haastii) is the largest kiwi in New Zealand. It is endemic but threatened with populations only in the northwest of the South Island.
One may recognise the roa by its ashy and grey feathers that are banded horizontally containing spots of whiter tones. Roa 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 Kiwi only breed one egg at once.
