On a trip to your beautiful country in January of last year, although we had been told we would no doubt not see a Kiwi Bird since they are nocturnal, we actually see a Kiwi Bird in at Rainbow Springs.

Kiwis' wings are tiny, at around 1 inch 3 cm. Each wing has a small claw on the tip, though the claw has no known use. Kiwis are found only in New Zealand in forests, scrublands and grasslands. They sleep in burrows, hollow logs or under dense vegetation. Kiwis are typically nocturnal, which means they sleep during the day and are active during the night. Throughout the night, they spend their time foraging for food.

When it's not foraging, it is patrolling its territory. It will leave behind highly odorous droppings to mark its area as it walks. The only other kiwis allowed in its territory are its spouse, its young and its adult children. If another kiwi does wander into another's territory they will fight. Kiwis are omnivores. They munch on worms, grubs, bugs, berries and seeds that they find with their excellent sense of smell. Kiwis are the only birds that have nostrils on the tips of their beaks.

Most birds have nostrils closer to their faces. Kiwis sometimes mate for life. Kiwi pairs use gentle grunts and snuffles with each other and their chicks , and males purr during mating. Pairs do fight, and the larger female may kick the male away if she is not in the mood for his company.

An adult male and female kiwi typically pair for life, but a female may choose a new male if a more desirable one wanders by. The male doesn't have beautiful songs or fancy feathers to attract a female. Instead, he follows one around constantly while grunting.

If she's not interested, the female might wander off or try to scare him away. Breeding season is late winter to early summer. Nests might be in hollow logs or in underground burrows dug by the male. The female kiwi lays up to six eggs every year.

Kiwi eggs are smooth and white, off-white, or pale green in color. They are also huge in comparison to the mother: one egg might reach up to 20 percent of her weight; that would be like a pound 54 kilograms human female giving birth to a pound 11 kilograms baby! Compared to the relative weights of other birds and their eggs, the female kiwi should weigh about 31 pounds 14 kilograms rather than its typical weight of 2 to 8 pounds 0. Kiwi eggs contain almost twice as much yolk as most birds their size and have natural antibacterial and antifungal properties.

How did the kiwi evolve to create such a huge egg? The large egg results in a long incubation period. As ancestral kiwis decreased in size, the egg stayed the same size, allowing for a more developed precocial chick needing less parental care. After the egg is laid, the male takes over parenting duties. He incubates the egg and maintains the nest for nearly 75 to 85 days, but if the female returns to lay another egg, the male has to sit on the clutch that much longer.

Unlike most bird parents, kiwis do not turn their eggs. Lacking an egg tooth, the chick must kick its way out of the shell.

It hatches wearing shaggy adult feathers and looking like a miniature version of its parents. No ugly baby phase for these birds! The youngster is not fed by the adults but gets its nourishment from a large reserve of yolk in its abdomen. The chick stays in the nest for its first few days, gaining strength. The young kiwi then leaves the burrow and, accompanied by Dad, begins the search for food.

It stays with the male up to 20 days and may stick around in the adults' territory for months or even years.

The kiwi existed for millions of years with only one natural predator —the now-extinct laughing owl—and no threats of any kind. When the Maori people established themselves in New Zealand in the s, they used kiwi feathers to adorn cloaks worn by their chiefs and used the birds as food, hunting them at night by imitating kiwi calls.

But in the late s, settlers moved into kiwi territory, bringing dogs, cats, ferrets, stoats, and rats that ate kiwi eggs or the birds themselves. The settlers prized kiwi feathers, too—for trout flies! Kiwi leg bones were popular as well for making pipe stems. Coins, postage stamps, fighting troops, and shoe polish all carry the name or image of the unique bird. Today, 80 percent of kiwi habitat has been destroyed, and the birds continue to fall prey to dogs, weasels, cats, ferrets, pigs, people, cattle guards, cars, swimming pools, and possum traps.
