Endangered native birds of New Zealand
New Zealand is home to a diverse range of flora and fauna, with a significant proportion of its native species found nowhere else on earth. Unfortunately, many of these species are now endangered, with habitat destruction, introduced predators, and other human impacts driving them to the brink of extinction. One of the most iconic and endangered native birds of New Zealand is the Kokako.
The Kokako is a large, grey-blue forest bird with a distinctive wattle of bright blue skin hanging from its throat. Once widespread throughout the country, the Kokako has suffered a dramatic decline in population over the last century due to habitat destruction and predation by introduced species such as rats, stoats, and possums. Today, the Kokako is one of New Zealand’s most threatened bird species, with an estimated population of just 4000 individuals.
- The major threats facing the Kokako include:
- Habitat loss and fragmentation due to deforestation and agricultural development.
- Predation by introduced mammalian predators, which are responsible for the decline of many native bird species in New Zealand.
- Competition with introduced bird species for food and nesting sites.
Conservation efforts to protect the Kokako and other endangered birds in New Zealand include the establishment of predator-free islands and fenced mainland sanctuaries where threatened species can breed and thrive in safety. These efforts have been successful in boosting populations of some endangered birds, and there is hope that with continued conservation efforts, species like the Kokako can be brought back from the brink of extinction.
In addition to the Kokako, there are many other endangered native birds in New Zealand. Some of the most threatened species include:
| Species | Threats | Conservation status |
|---|---|---|
| Kakapo | Predation by introduced mammals, habitat loss, low reproductive rate. | Critically endangered |
| Kiwi | Predation by introduced mammals, habitat loss, low reproductive rate. | Endangered |
| Yellow-eyed penguin | Predation by introduced mammals, habitat loss, disease. | Critically endangered |
| North Island kokako | Habitat loss, predation by introduced mammals, competition with introduced bird species. | Endangered |
Protecting these and other endangered species is critical not only for their survival, but for the health and resilience of New Zealand’s unique ecosystems. As one of the few countries in the world with such a high proportion of endemic species, New Zealand has a responsibility to protect and preserve its natural heritage for future generations.
Characteristics of the Kokako
The kokako, also known as the blue-wattled crow, is a beautiful bird native to New Zealand. It is a unique and highly specialized species known for its distinctive appearance and interesting behavior. Here are some of the characteristics of the kokako:
- The kokako is a medium-sized bird, with a length of up to 45 cm and a weight of up to 350 grams.
- It has striking blue-grey plumage, a distinctive “mask” of bare skin around the eyes, and long, bright orange or red wattles hanging from its cheeks.
- The kokako has a strong, melodious call that has been compared to the sound of a bellbird. It is a complex song, with different parts sung by males and females, and can be heard for up to a kilometer away.
Habitat and Distribution
The kokako is endemic to New Zealand, meaning that it is found nowhere else in the world. It was once widespread across both the North and South Islands, but due to habitat loss and predation by introduced mammals, its range has become severely reduced. Today, the kokako is mainly found in a few small pockets of forest in the North Island. The largest populations are in the Hunua and Waitakere Ranges near Auckland, and the Pureora Forest Park in the central North Island.
Diet and Behavior
The kokako is an omnivore, feeding on a variety of fruits, flowers, invertebrates, and even small animals like lizards and snails. It is known for its unique behavior of “leaf-bashing,” where it strikes a leaf with its bill to dislodge insects or other small prey hiding inside.
The kokako is also a territorial bird, and can be quite aggressive towards other birds or animals that encroach on its space. It has been observed chasing off other birds like tui and bellbirds, and even attacking possums and stoats that come too close to its nest.
Conservation Status
Due to its declining population, the kokako is classified as “At Risk/Recovering” under the New Zealand Threat Classification System. Conservation efforts are in place to protect and restore its habitat, and to control predators like rats, stoats, and possums that threaten its survival. The kokako is a symbol of New Zealand’s unique biodiversity, and efforts to conserve it are a crucial aspect of the country’s conservation efforts.

Distribution of Kokako in New Zealand
The Kokako, a bird species endemic to New Zealand, has a scattered distribution across the country. Their range has greatly declined due to habitat destruction, predation, and fragmentation. Currently, their population is limited to several isolated population groups that are separated by large stretches of unsuitable habitat.
- The North Island is the primary home of the Kokako with about 95% of the total population. These birds can be found in areas such as Hunua Ranges, Tararua Ranges, Urewera National Park, and Pureora Forest Park.
- The South Island, on the other hand, only has a few small populations notably in Marlborough Sounds and Fiordland National Park
- Stewart Island had once been home to a distinct subspecies of Kokako, the Stewart Island Kokako but no sightings of the bird have been reported since the 1960s, and it is now presumed extinct.
The table below provides a more specific breakdown of the current Kokako population in New Zealand:
| North Island Populations | Population Size |
|---|---|
| Hunua Ranges | Unknown |
| Tararua Ranges | 50-200 |
| Pureora Forest Park | Unknown |
| Maungatautari Ecological Island | 60-100 |
| Urewera National Park | 100-150 |
| Whirinaki Forest Park | Unknown |
As seen in the table, some populations have an unknown number of individuals due to the limited amount of research conducted on this elusive bird. Nonetheless, efforts are being made to help increase the Kokako population by implementing predator control, building conservation sanctuaries, and creating forest restoration initiatives.
Threats to the Survival of Kokako
Kokako is a native bird of New Zealand that is threatened by several factors. Although protective measures have been taken to save this species, it is still on the brink of extinction. Let us examine some of the major threats to the survival of kokako.
