Feathers of the flightless kakapo are being flown around the world as part of a Massey biologist’s quest to understand the role of the critically endangered native parrot’s sense of smell and the power of male feather fragrance on breeding behaviour.
One of the rarest birds of all is New Zealand's Kakapo, which is a flightless bird. The species has been largely wiped out by introduced predatory mammals such as feral cats, stoats, and possum.Being hunted as game and for its feathers.They reproduce only every 3-5 years. For over 100 years New Zealand has made efforts to protect the species. In 1989 it instituted a new recovery program, and now can be seen a slow but steady increase in numbers.
The Hyacinth Macaw (Anodorhynchus hyacinthinus), or Hyacinthine Macaw, is a parrot native to central and eastern South America. With a length (from the top of its head to the tip of its long pointed tail) of about 100 cm (3.3 ft) it is longer than any other species of parrot. It is the largest macaw and the largest flying parrot species, though the flightless Kakapo of New Zealand can outweigh it at up to 3.5 kg.
