Where Do Kiwi Birds Live?
Kiwi, exclusive to New Zealand, are flightless and nocturnal birds. Interestingly, they possess the second-largest egg in proportion to their body weight among all bird species. The kiwi, comparable in size to a chicken, is a diminutive and flightless bird native exclusively to New Zealand.
This unique avian species, along with its larger relatives such as the cassowary, emu, ostrich, and rhea, belongs to the classification of birds known as ratites.
What’s the Lifespan of Kiwi Birds?
Kiwi birds have a lifespan ranging from 25 to 50 years. When kiwi chicks hatch, they are already covered in feathers. At around five days old, they venture out of the nest to forage for food and are self-sufficient from that point on, as their parents do not feed them. Juvenile kiwis experience a gradual growth process, taking approximately three to five years to reach their full adult size.
