  • They eat at night and use their bill to probe the ground up to a depth of 12cm. 

Reproduction & Breeding

  • Adult Kiwi birds establish a territory, dig a nesting burrow, and mate.
  • In certain species, such as the North Island brown kiwi birds, only the male incubates the large egg (or two) that the female produces.
  • A completely feathered chick emerges from the egg to confront its first few days of life.
  • Birds require anywhere from 16 months to three years to reach sexual maturity and be ready to breed.
  • In most cases, hatching takes place between July and February. In the avian world, the female North Island Brown Kiwi possesses two functioning ovaries, which is unique.

Baby

  • Their babies are called Kiwi chicks.
  • They are mini-adults when they hatch.
  • They have delicate, pink beaks, are fully feathered, and have open eyes.
  • Their parents don’t have to feed their babies because the rich egg yolk can keep them alive for several days.
  • A kiwi chick may only weigh 80% of its hatching weight after this period.

Egg

  • While it is unpleasant to lay such a huge egg, there is a benefit.
  • The yolk content of most bird eggs is 35-40%, whereas the kiwi’s egg is 65 percent.
  • The nutrient-dense yolk ensures that kiwi chicks hatch completely feathered and self-sufficient, and it is so large that it sustains them for the first week of life.

Etymology

  • New Zealand’s flightless bird, the Kiwi birds (n.), was named in 1835 after the Maori kiwi, which is considered to be of imitative origin.

  • They have a shrill half-scream, a half-whistle cry that sounds like “kee-wee, kee-wee,” which is pronounced, “kee-wee, kee-wee.” When they’re active at night, this sound helps them maintain track of each other. They may also hiss, snort, grunt, and snuffle.
