This book takes you to the heart of Kauai’s birds. You will learn the endemics, the passerine migrants, the seabird colonies, the use of birds culturally, and how to find them. You will learn why birders all over the world place Kauai at the tail end of their travel plans after they read this book.
The Ecosystems That Shape Kauai’s Birds
Kauai is small but exceptionally diverse in habitats. There are many birds in all of the habitats to create one of the most bird-dense habitats in the Pacific.
Rainforests and Valleys
Rainforests cover the interior of Kauai. ʻIʻiwi and ʻApapane birds live in flowering ʻōhiʻa trees.
Cliffs and Coastlines
Seabirds like boobies, frigatebirds, and tropicbirds live on huge ocean cliffs of the Nā Pali Coast and Kīlauea Point.
Wetlands and Rivers
Hanalei National Wildlife Refuge provides ducks, herons, and migrant birds wetlands.
High Mountains and Swamps
Alaka’i Swamp is the wettest spot on earth. It also provides habitat to unusual native birds not present anywhere else on the planet.
Beaches and Lowlands
Beaches provide beach habitat for plovers, shorebirds, and wild chickens of course world-renowned Kauai.
Native Birds of Kauai
Nēnē – The Hawaiian Goose
Nēnē is the official state bird of Hawaii and conservation saved Nēnē from extinction. Nēnē is gray-speckled brown-patched soft goose and a very soft creature. It is to go back in time and see ancient Hawaii and see a Nēnē walk along a grassy meadow.
ʻApapane
Small, red, and swift, the ʻApapane is a nectar-feeding honeycreeper that flashes down flowers on the ʻōhiʻa, sucking nectar from their downward-projecting beak. It trills in the woods.
ʻIʻiwi
A Hawaiian myth. Handsome scarlet with curved, projecting bill, the ʻIʻiwi is a bird that’s a flying flower. Too bad it’s now only seen on Kauai, but devoted birders still search it out in out-of-the-way mountains.
Pueo – Hawaiian Short-Earned Owl
It is different from the others as it is an owl during the day. It flies low over the fields on the ground to catch mice. Pueo, in Hawaiian religious beliefs, is a protector angel.
Hawaiian Honeycreepers
Some honeycreepers are seen in Kauai, a multi-coloured ensemble of little birds which differentiated into types. They are products of the intelligence of evolution. Some of them have nectar-specialized hooked beaks, and others have seed-specialized short beaks.
Birds Which Appear Here Only
Some birds which appear here only are visible. They are not seen anywhere else on our earth.
- ʻAkikiki (Kauai Creeper): Insectivorous, gray bird. Extremely uncommon and only in deep rainforests.
- ʻAkekeʻe: Recognizable by its crossed bill, which it uses to pry flower buds open so that the bird will get a chance to feed on insects. Extremely uncommon as well and limited to Alaka’i Swamp.
- Anianiau: Smallest Hawaiian honeycreeper in the world. Extremely yellow and extremely active, and typically in groups.
These birds are a reminder of the helpless condition of animals in islands. They simply occupy space here by themselves, hence Kauai is a reservoir species.
Introduced Birds of Kauai
Not everything that flies in Kauai is native. Some of them were introduced to this area by human beings knowingly and unknowingly.
Wild Chickens
As probably the most iconic of arrivals in Kauai. Feral chickens infest the islands—parking lots, beaches, backcountry trails. They are a cross between chickens brought to the islands by the Polynesians and subsequently crossed with farm escapees. Crowing is an island sound.
Common Myna
India-birthed, territorial, loud, ubiquitous in towns. They displace native birds out of space to nest.
Zebra Dove
Small and gentle, these doves are common in yards and gardens. Their soft cooing adds charm to mornings.
Northern Cardinal
Bright red and striking, cardinals were introduced in the 19th century. They add color but also compete with native birds.
Introduced birds make Kauai lively, but they also put pressure on the fragile native ecosystem.
Seabird Colonies on Kauai’s Cliffs
Kauai’s steep cliffs provide perfect nesting grounds for seabirds.
- Red-Footed Booby – Blue bills, red feet, and dive-bombing to sea after fish. Kīlauea Point has a famous colony.
- Great Frigatebird – Large with really unbelievably long wings and forked tail. Red throat pouches are displayed by males in a despairing bid to attract females. Gliders par excellence.
- White-Tailed Tropicbird – Waif-like with long tails, flying lazy arcs out over cliffs in widening semicircles. White feathers create a striking contrast against green and blue terrain.
- Shearwaters – Breeding grounds of the majority of the species, such as Newell’s Shearwater, are burrows. They are predators and light-kill. They are being conserved by conservationists.
Where to Watch Birds on Kauai
- Kīlauea Point National Wildlife Refuge – Best spot to view sea birds eye-level. Frigatebirds, boobies, and tropicbirds number hundreds glide wind over cliffs.
- Hanalei National Wildlife Refuge – Wetlands that serve as shelter for ducks, stilts, and herons. Suitable for winter migrant birds.
- Alaka’i Swamp Trail – Strenuous hike with reward of rare grassland endemics like ʻAkikiki and ʻAkekeʻe.
- Wailua River and Environs – Top spot for waterbirds and introductions.
- Daily Kauai – Even in town or at the beach, chickens, cardinals, and mynas add some pizzazz for birders.
Birds in Hawaiian Culture and Mythology
Birds played a very important role in Hawaiian religious life for centuries.
- Pueo owl is an ancestral spirit, usually reserved for ancestors.
- The ʻIʻiwi and other honeycreepers were admired for their feathers, which were used in cloaks and helmets of chiefs.
- Birds were messengers between the gods and humans.
- The Nēnē symbolizes resilience, surviving near extinction.
Every bird carries a story. By learning them, visitors connect not just to nature, but to Hawaiian culture itself.
Conservation Challenges for Kauai’s Birds
Kauai’s birds face many threats.
- Habitat loss: Deforestation and development reduce forests.
- Wildlife intrusions: Pigs, rats, and cats consume chickens and eggs.
- Disease: Mosquitoes transmit native malaria infection to native birds.
- Climate change: Heat of summer prolonged to enable disease-transmitting mosquitoes deeper into the forest.
Conservation of wetlands, preservation of predators, and replanting continuing. Volunteers and conservations help maintain habitats such as critically endangered ʻAkikiki.
