The island’s rich vegetation, coupled with the surrounding ocean’s marine life, makes it a perfect location for birds to feed, breed, and live. Apart from being an attraction for tourists and bird enthusiasts, the birds also play a vital role in the island’s ecosystem.
The diverse range of birds found in Kauō underscores the island’s commitment to preserving and protecting its natural environment.
This article will provide an in-depth analysis of the different types of birds found in Kauō, their habitat, feeding habits, and their role in maintaining the ecological balance on the island.
1. Laysan Albatross
The Laysan albatross is a large seabird found in the North Pacific Ocean. Most of its population (99.7%) can be seen residing in the Northwestern Hawaiian Islands, where they form strong colonies and thrive in their natural habitat.
They are small for an albatross but still have distinguishable features such as long wingspans that help them soar gracefully above oceans while searching for food over great distances with ease.
It’s estimated to have 1.18 million birds worldwide and continues to expand or re-expand its range throughout other areas of the oceanic region too.

2. Laysan Duck
The Laysan duck is a unique bird species found exclusively in the Hawaiian Islands. It is also known as the Laysan teal due to its prominent dabbling behavior.
Fossil records indicate the Laysan duck once inhabited several islands in the archipelago, but it now exists in only three locations.
Interestingly, the duck possesses physical and behavioral characteristics that relate to its predator-free environment.
Unfortunately, due to human activity and other related factors, the duck experienced significant declines in its population, and by 1860, it was on the brink of extinction.
Consequently, conservation efforts were initiated to protect the remaining population.
Today, the Laysan duck is still considered a vulnerable species, but conservation efforts have enabled population recovery, and the bird is now in better shape than in previous years.

3. Millerbird
The Millerbird is a small bird belonging to the family Acrocephalidae. It has two subspecies, with one already extinct. The Nihoa Millerbird, found only on the island of Nihoa, is the last surviving race.
It is classified as critically endangered. The bird’s habitat is limited, and it faces threats from habitat loss, diseases, and predators.
Efforts are being made to protect and conserve the delicate ecosystem on Nihoa and ensure the survival of the Nihoa Millerbird.
It has small proportions, unique nesting behavior, and a distinct song.
The Millerbird’s conservation status highlights the need for responsible environmental stewardship and the importance of protecting vulnerable species.
Scientific classification:
| Kingdom | Animalia |
| Phylum | Chordata |
| Class | Aves |
| Order | Passeriformes |
| Family | Acrocephalidae |
| Genus | Acrocephalus |
| Species | A. familiaris |
4. Laysan Finch
The Laysan finch is a bird endemic to the Northwestern Hawaiian Islands. It belongs to the Hawaiian honeycreeper family and is closely related to the Nihoa finch.
Named after the island it was first discovered on, the Laysan finch was later introduced to a few other atolls. This species is one of only four remaining finch-billed Hawaiian honeycreepers.
Despite its small size, it is a hardy bird that has managed to adapt and survive in a challenging environment.
The Laysan finch is a valuable part of Hawaii’s ecosystem and its preservation is important for the continued health and biodiversity of the islands.

5. Laysan Rail
The Laysan rail bird, also known as the Laysan crake, was a flightless species found exclusively on the Northwest Hawaiian Island of Laysan. Unfortunately, this bird went extinct due to habitat loss caused by domestic rabbits and World War II.
Laysan Island was an essential breeding ground for many seabirds, including this railbird. The loss of habitat led to a decline in the population of Laysan railbirds, and the species couldn’t recover from it.
The scientific name for this bird is Zapornia palmeri, named after Henry Palmer, who collected specimens.
It is a tragedy that this unique bird species is no longer with us, but it serves as a reminder that we must protect our natural environment and the species that call it home.
Scientific classification:
| Kingdom | Animalia |
| Phylum | Chordata |
| Class | Aves |
| Order | Gruiformes |
| Family | Rallidae |
| Genus | Zapornia |
| Species | †Z. palmeri |
6. Nihoa Millerbird
The Nihoa miller bird, also known as Acrocephalus familiaris kingi, is a unique bird subspecies that feeds primarily on Miller moths. Its dark sepia feathers, white belly, and dark beak give it a distinctive appearance.
This small bird is only 5 inches long and can only be found on the island of Nihoa in the Northwestern Hawaiian Islands.
Due to its limited geographic range, conservationists have taken measures to help the species by translocating birds to Laysan Island.
The Nihoa millerbird is an important part of the island’s ecosystem, and its survival is crucial. With careful management and conservation efforts, this bird subspecies can thrive for generations to come.

7. Telespiza
The Telespiza bird is a unique genus of Hawaiian honeycreeper. With all species being endemic to the Hawaiian Islands, they are considered highly specialized.
This means that they have evolved to adapt to the unique ecological conditions of Hawaii. Unfortunately, some species of Telespiza birds are not doing well in today’s changing environment.
There are even some species that are considered extinct. Despite this, there are still some populations of Telespiza birds that can be found on the islands. These birds have bright plumage and can often be seen feeding on nectar or insects.
Overall, the Telespiza bird is an important and fascinating part of Hawaii’s unique natural heritage.

8. Laysan Millerbird
The Laysan miller bird was a bird species that subsisted heavily on various species of moths. Its physical characteristics were similar to the Nihoa miller bird, with a brown dorsal side and grayish belly.
Sadly, this subspecies is now extinct. The bird was named after its favorite food, which was moths from the genus Agrotis, including the endemic and now-extinct Agrotis laysanensis.
Its extinction is a tragedy, as it represents the loss of a unique and important component of the natural world.
The Laysan miller bird’s disappearance highlights the need for conservation efforts and the importance of protecting and preserving vulnerable species.
