Native Birds of Kauai: Explore Their Beauty and Facts
Yes, before most of the other birds came, the native birds of Kauai were living in a marvelous paradise. The migratory birds came from different habitat and this island proved to be the best habitat to survive.
Unfortunately; habitat loss, climate change and invasive species nearly eliminated almost 70 percent of Hawaii’s native Kauai birds. This is to educate yourself on what you can expect from nature. Discover more about these birds!

Threats to Native Birds
- Avian Malaria: Rising temperatures are spreading mosquitoes, destroying native bird populations.
- Invasive Species: Eggs and chicks of ground nesting seabirds are vulnerable to rats, mongoose and feral cats.
- Habitat Destruction: Their natural habitat is reduced by agricultural expansion as well as urbanization.
Nearly 90 % of the native birds live in the high-elevation forests, which are cooler and have lower mosquito populations. Let’s learn some fascinating facts about some of the native birds of Kauai.

Akikiki

Scientific Name1 | Oreomystis bairdi |
Population | Only five individuals left (estimated in July 2023) |
IUCN Status | Highly endangered species |
Habitat
Birds of Kauai are split among a variety of habitats. Akikiki inhabit montane rainforests, and their ‘home’ is Koke’e State Park.
Description
The main and highly endangered native bird of Kauai, the Akikiki is about 13 cm in length and 12–17 g in mass. Their head is dull gray, back and side, and their legs and bills are pink.
This little bird is quite unlike any other Kauai bird because it has gray plumage, conspicuous white eye rings and a shorter tail.
Breeding and Feeding
Their female partners lay one or, at most, two eggs each year. Chicks follow their parents for three months after fledging. They eat mainly insects and other invertebrates and feed on dead trees, barks and trunks.
Apapane

Scientific Name1 | Himatione sanguinea |
Population | 100K (Kauai), 1.25 million (world) |
IUCN Status | Not Vulnerable |
Habitat
Apapane lives in high-elevation native forests on all the larger Hawaiian Islands, including the Kauai, O’ahu, and big island.
Description
The Apapane is a beautiful native bird of Kauai Hawaii. It is 13 cm in length and 16 g weight. It has a unique sight with its yellow, brown, and grey plumages accented by red, black, and white colors. Its white bill tip and exceptional flying abilities make it a standout in Kauai’s bird population.
Breeding and Feeding
Apapanes nest in ōhiʻ trees and tree cavities. They breed from October to November. The female lays 1 to 4 eggs, which hatch in 13 days. The males do not visit their female partners while incubating. Apapanes feed on insects and spiders. Their specialized bills assist them with nectar feeding. One strange fact is that butterflies are their favorite food.
Anianiau

Scientific Name1 | Magumma parva |
Population | 88703 individuals |
IUCN Status | Close to endangered |
Habitat
The Anianiau lives in various habitats, ranging from wet forest elevations above 600 meters to dry valleys northwest of the island. Other habitats include the koa tree (Acacia koa) and ʻōhiʻa lehua tree (Metrosideros polymorpha).
Facts and Description
These are 10 cm in length and 10 g in mass. The Anianiau is the smallest yellow bird commonly found on Kauai. Male birds are yellow, while their female partners give a yellowish-green look. Anianiau has yellow legs and a pinkish bill.

Facts and Description
The Akeke’e are generally green, with a blue crossbill and a black mask around their neck. They have a specialized bill with incredible adaptive radiation from closely related species.
Breeding and Feeding
The breeding season for Akeke’e starts in March, and their chicks probably fledge by mid-July. They build more than one nest and forage alone or in pairs. They are highly social birds. Their specialized bill helps them prey on spiders, caterpillars, and psyllids. Occasionally, they feed themselves on plant nectar.

Female bird lay 1–4 eggs with dark markings on them. They mostly incubate for 14 days. While chicks don’t get old enough to feed themselves, their parents feed them until then. Amakihi are well-fed birds that consume fruit juice, flower nectar, insects, and tree shrubs.
Kauaʻi ʻelepaio

Scientific Name2 | Chasiempis sclateri |
Population | Estimated 20,000, it grows by 13% yearly |
IUCN Status | Recovery Mode |

Conservation Efforts
Mosquito Control Projects: This project uses techniques such as IIT (Incompatible Insect Technique) to control mosquito populations to protect birds like the Akikiki.
Habitat Restoration Efforts: By reforestation and fencing projects, invasive species don’t overrun bird habitats.
Breeding Programs: But organizations such as the Kauaʻi Forest Bird Recovery Project breed and release endangered birds into the wild.
List of other native forest birds of Hawaii
List of other native forest birds of Hawaii include ʻŌmaʻo, also called Hawaiian Thrush, ʻAkiapōlāʻau, Hawaiʻi ʻākepa, ʻAlawī, and ʻIo or Hawaiian hawk.
