EDGE Analysis

The kiwi is the unofficial national symbol of New Zealand and is the name by which national people are known. There are five species of kiwi, all endemic to the country. Kiwi feathers are unusual having a shaggy, fur-like quality and hanging loose against the body. All kiwis are flightless due to very reduced wings. This makes them very vulnerable to predation by invasive mammalian predators. Dogs and ferrets are the main threat to adult kiwis, whereas younger birds tend to be predated upon by stoats and cats.
