Most Kiwis Mate For Life

Here’s a heartwarming bit of information for those of you who love romantic kiwi facts. On average, male kiwis reach sexual maturity around 18 months old while female kiwis become sexually mature at 3 years old. Once kiwis are ready to mate, a male will follow a female around and grunt until she returns his affections. Many of these partnerships endure for years, and it’s typical for kiwis to mate for life.

Although many kiwis are monogamous and stay together for years, there are exceptions to this rule. Apparently, even kiwis struggle to keep the fire going after so long and begin to develop wandering eyes. Within established couples, female kiwis are more likely than males to end the relationship, as they often end the partnership if they find a male they like better than their current mate.

Kiwis Can Live For a Long Time

Many birds are blessed with long lifespans. For example, parrots often live up to 70 years old and may be able to reach up to 100 years old. Scientists believe that birds’ high metabolic rate, body temperature, and other genetic factors contribute to their extended lifespan. They also suffer less oxidative damage than most mammals, which could also allow them to age more slowly.

Although they are land-based, kiwis are also quite long-lived. If they can reach maturity and avoid predators, kiwis can live anywhere from 25 to 50 years. That said, few kiwis ever live this long in the wild, although it’s possible that kiwis may be able to live even longer given the right environmental conditions.

Kiwis Have An Excellent Sense of Smell

Next up we have what may be the most surprising entry on our list of kiwi facts. Generally speaking, birds aren’t known for having a superior sense of smell. Researchers long believed that most birds sacrificed their sense of smell in exchange for excellent eyesight. However, new evidence suggests that some birds possess a keen sense of smell, and the kiwi may rank among the best when it comes to olfactory prowess.

Kiwis possess a highly-developed sense of smell. As a matter of fact, they are the only birds with nostrils, which are located at the end of their bills. Using only their sense of smell, kiwis can locate worms and insects located underground. While they may also use auditory or tactical tools to help them find food, smell likely serves as their primary sense.

Kiwis Share More in Common With Mammals Than Most Birds

While kiwis belong to the class Aves, which contains all the world’s bird species, they share more in common with mammals than most other birds. Unlike most birds and like some mammals, they possess poor eyesight. Their limited field of vision is largely due to their small eyes, as they have the smallest eyes of any bird species.

You can also include bone structure among the traits that kiwis share with mammals. While almost all birds possess hollow bones, which reduces their weight and makes flight possible, kiwis have dense bones full of marrow. Additionally, their feathers differ from other birds and more closely resemble bristle-like hairs than true feathers.

The Term Kiwi is Multifaceted, Historic, and Hotly Contested

Before we dive into any other kiwi facts, we should first explore the meaning of the word kiwi. The word kiwi not only refers to the bird but also to people from New Zealand as well as the kiwifruit or Chinese gooseberry. Today, the word kiwi serves practically as a stand-in for the island of New Zealand, its people, and its culture.

As for the source of the word kiwi, scientists still can’t agree on its origin. In the Maōri language, the word kiwi supposedly derives from the sound of the kiwi bird’s call. However, other linguists contend that kiwi comes from the ancient Polynesian word for the bristle-thighed curlew, a migratory bird found on Pacific islands that closely resembles the kiwi.

Kiwis Cannot Fly

This next entry is likely the most well-known of all the kiwi facts to appear on this list. As you may or may not know, kiwis cannot fly. Like its much larger ratite cousins, kiwis possess no keel on the sternum, which serves to anchor the wing muscles of birds. As a result, they lack the physical structure required to generate enough force to lift their bodies off the ground.

Moreover, the wings of a kiwi are much smaller compared to most birds. In fact, they are so small that they appear practically invisible to the naked eye as they lie buried under kiwis’ hair-like feathers. Despite their lack of a need for wings, kiwis retained this quintessential avian feature throughout their evolution as they adapted to life on the ground.
