The wildlife of Hawaiʻi Volcanoes National Park is unlike that of almost any other national park in the United States. Thousands of miles of open Pacific Ocean isolated the Hawaiian Islands from continental ecosystems, allowing the animals that successfully reached these remote volcanic islands to evolve in remarkable ways.
Native birds dominate the park’s wildlife story. Crimson ʻapapane move through flowering ʻōhiʻa forests, bright red ʻiʻiwi search for nectar with curved bills, nēnē graze along volcanic landscapes, and ʻio circle above the forest canopy. After dark, ʻōpeʻapeʻa—the Hawaiian hoary bat—emerges to hunt insects as Hawaiʻi’s only surviving native terrestrial mammal.
The park’s wildlife extends all the way from the coast to the high slopes of Mauna Loa. Endangered hawksbill turtles nest along remote beaches, humpback whales pass offshore during winter, Hawaiian petrels nest high in volcanic country, and an extraordinary collection of endemic insects and spiders occupies forests, lava fields, caves, and other habitats.
Hawaiʻi Volcanoes National Park protects seven major ecological zones, from coastline and lowland environments to rainforest, upland forest, subalpine terrain, and alpine landscapes. That diversity creates habitat for species found nowhere else on Earth.

🌎 Why Hawaiʻi’s Wildlife Is So Unusual
Hawaiʻi is one of the most isolated island groups on Earth.
Before humans arrived, an animal could reach the islands only by flying, floating, being carried by another organism, or surviving an extraordinary journey across thousands of miles of ocean.
Large land mammals, snakes, amphibians, and many other familiar groups never naturally established themselves here.
Birds, insects, spiders, snails, and one lineage of bat were among the successful colonizers.
Once isolated on the islands, their descendants adapted to new habitats and ecological opportunities. Over many generations, populations diverged and new species evolved.
That process produced an unusually high level of endemism—species found naturally nowhere else on Earth.
More than 90 percent of Hawaiʻi’s native terrestrial plants and animals are endemic to the Hawaiian Islands.
Hawaiʻi Volcanoes National Park preserves some of the finest remaining habitat for these extraordinary species.
🌋 Wildlife From the Coast to the Volcanoes
The park’s wildlife diversity is closely connected to elevation.
Hawaiʻi Volcanoes stretches from the Pacific coast to high volcanic terrain on Kīlauea and Mauna Loa.
Conditions change dramatically along the way.
Warm coastal habitat gives way to lowland vegetation, rainforests, upland forest, subalpine shrublands, and eventually sparse alpine environments.
Rainfall also varies enormously.
Some sections receive abundant moisture, while the Kaʻū Desert and other areas can be surprisingly dry.
An animal adapted to wet ʻōhiʻa forest may have very different needs from a seabird nesting among barren lava at high elevation.
This diversity of ecological zones is one reason the park protects such an unusual collection of wildlife.
🪿 Nēnē: Hawaiʻi’s Famous Native Goose
The nēnē is perhaps the most recognizable animal in Hawaiʻi Volcanoes National Park.
Also known as the Hawaiian goose, it is the official state bird of Hawaiʻi and a federally threatened species.
Its ancestors probably resembled Canada geese that reached the Hawaiian Islands long ago.
Over generations, the isolated population adapted to life on volcanic islands.
Nēnē spend considerably more time walking than swimming. Their legs are relatively long, and their feet have less webbing than those of many aquatic geese.
Those features suit a bird that often walks across lava fields, grasslands, shrublands, roadsides, and upland habitats rather than living primarily around ponds.
They feed on grasses, leaves, seeds, flowers, berries, and other vegetation.
🪿 From Thousands of Nēnē to Near Extinction
Nēnē were once far more numerous.
The National Park Service estimates that perhaps 25,000 lived in Hawaiʻi when Europeans arrived during the late 18th century.
Their numbers collapsed as habitat disappeared and introduced animals transformed Hawaiian ecosystems.
Mongooses, feral cats, dogs, and rats preyed on eggs, goslings, and sometimes adults.
Cattle, goats, and pigs altered vegetation and competed for habitat.
Hunting added additional pressure.
By the middle of the 20th century, only a tiny number of nēnē survived.
Captive breeding and reintroduction programs prevented extinction, and Hawaiʻi Volcanoes National Park became an important center of nēnē recovery efforts.
The population has increased substantially, but the species still requires active conservation.
🚗 Watch for Nēnē on the Roads
One of the greatest modern dangers to nēnē is surprisingly ordinary: vehicles.
The birds frequently walk and feed beside park roads.
Because they evolved in an environment without cars or large terrestrial predators, they may show relatively little fear of people and vehicles.
Never assume a nēnē will move out of the way.
Reduce speed in posted nēnē areas and remain alert along Crater Rim Drive, Chain of Craters Road, Highway 11, and other park roads.
Feeding the birds makes the problem worse.
A nēnē that receives food from visitors can begin approaching parking lots, roads, and cars in search of additional handouts.
Never feed one, even if it walks directly toward you.
🐣 Nēnē Nesting Season
Nēnē can be seen throughout the year, but nesting season makes protecting them especially important.
Breeding and nesting generally take place from fall into spring.
Pairs may establish nests on or near the ground, and families with goslings can appear in grassy areas, along roads, and around other relatively open habitats.
The National Park Service may temporarily restrict access to specific locations when birds are nesting or raising young.
Respect these closures.
A visitor trying to get a closer photograph can cause adults to leave a nest, force a family away from good feeding habitat, or place birds closer to roads.
The best nēnē encounter is one where the geese continue behaving as though you were not there.
🔴 ʻApapane
The ʻapapane is one of the most common native Hawaiian forest birds visitors may encounter.
Its brilliant crimson body, black wings and tail, and contrasting white feathers beneath the tail make it particularly striking.
ʻApapane are Hawaiian honeycreepers and have a close relationship with ʻōhiʻa lehua forests.
They feed heavily on nectar from the red blossoms of ʻōhiʻa trees while also eating insects.
When flowering conditions are good, ʻapapane may travel substantial distances in search of nectar.
Their calls are equally distinctive.
A single bird can produce an impressive variety of songs, chirps, and whistles, while large numbers create a remarkable dawn chorus in healthy native forest.
🌺 ʻApapane and ʻŌhiʻa Lehua
The relationship between ʻapapane and ʻōhiʻa demonstrates how closely Hawaiian wildlife is connected to native plants.
ʻŌhiʻa lehua can colonize relatively young volcanic landscapes and eventually form extensive forests.
Its blossoms provide nectar for native birds and insects.
As ʻapapane move among flowers, they can also contribute to pollination.
A productive ʻōhiʻa bloom may attract numerous birds, making flowering trees excellent places to stop and listen.
Healthy native forest is therefore essential to healthy native bird populations.
Threats such as invasive plants, disease affecting ʻōhiʻa, wildfire, and introduced animals can indirectly affect birds by changing the vegetation they depend upon.
🔴 ʻIʻiwi
The ʻiʻiwi is one of Hawaiʻi’s most beautiful birds.
Adults are vivid vermilion red with black wings and tails. Their most distinctive feature is a long, downward-curving orange bill adapted for feeding from flowers.
Like ʻapapane, ʻiʻiwi travel in search of nectar, particularly from ʻōhiʻa lehua.
Historically, the species occurred across a much broader elevation range.
Today, ʻiʻiwi are strongly associated with higher-elevation forests where cool temperatures limit the mosquitoes that transmit avian malaria.
In Hawaiʻi Volcanoes National Park, they are most likely to be found in higher native forest, including areas above roughly 4,500 feet.
The retreat of ʻiʻiwi toward cooler elevations illustrates one of the greatest threats facing Hawaiian forest birds.
🦟 Mosquitoes and Avian Malaria
Mosquitoes did not naturally occur in Hawaiʻi.
They arrived with people and eventually became carriers of avian malaria and other diseases that native Hawaiian birds had never previously encountered.
Many native species have little resistance.
At cooler high elevations, temperatures historically limited mosquito survival and reproduction, creating refuges for vulnerable forest birds.
As temperatures warm, mosquitoes can survive at increasingly high elevations.
That reduces the amount of disease-free forest available to species such as ʻiʻiwi.
For Hawaiian bird conservation, climate change is therefore not simply about temperature.
It can alter where disease-carrying insects live and shrink the safe habitat available to native birds.
🟢 Hawaiʻi ʻAmakihi
The Hawaiʻi ʻamakihi is another native honeycreeper, although its appearance is very different from the vivid red ʻiʻiwi.
Adults are generally greenish-yellow with a curved bill.
ʻAmakihi eat nectar, insects, spiders, and other small arthropods.
They are among the more adaptable native Hawaiian forest birds and can occur at lower elevations than several more sensitive species.
Scientists are particularly interested in ʻamakihi populations that persist in areas where avian malaria is common.
Some populations appear better able to survive exposure to the disease than highly vulnerable honeycreepers.
That does not make them immune to the many environmental threats affecting native forest habitat, but their persistence provides a fascinating example of wildlife adapting to a rapidly changing ecosystem.
🐦 Hawaiʻi ʻElepaio
The Hawaiʻi ʻelepaio is a small native flycatcher with an energetic personality.
These birds actively move among branches and leaves searching for insects.
They may pick prey from bark and foliage or catch insects in flight.
ʻElepaio also hold an important place in Hawaiian culture.
Traditional canoe makers watched the behavior of these birds when evaluating koa trees.
An ʻelepaio pecking repeatedly at a felled tree could indicate insects or decay within the wood, suggesting it might be unsuitable for a canoe.
Today, visitors have a chance to encounter ʻelepaio in native forest habitats within Hawaiʻi Volcanoes National Park.
Their active movements and distinctive calls can make them easier to hear than to photograph.
🐦 ʻŌmaʻo
The ʻōmaʻo, or Hawaiian thrush, occurs only on Hawaiʻi Island.
Its plumage is relatively subdued compared with the brilliant colors of the honeycreepers, but its voice can be much easier to notice.
ʻŌmaʻo inhabit montane rainforests, generally at elevations above about 3,000 feet.
Their diet consists primarily of native fruits supplemented with invertebrates.
That fruit-eating behavior makes the birds ecologically important as seed dispersers.
Seeds carried away from a fruiting plant and deposited elsewhere can help native forest regenerate.
A healthy ʻōmaʻo population therefore contributes to the forest that supports the birds themselves.
🦅 ʻIo: The Hawaiian Hawk
The ʻio, or Hawaiian hawk, is the only hawk native to Hawaiʻi.
It occurs naturally only on Hawaiʻi Island.
Visitors may see ʻio soaring over forests, open areas, agricultural landscapes, and volcanic terrain.
The birds occur in both light and dark color forms, so plumage alone can vary considerably.
ʻIo prey on insects, birds, and rodents.
Before humans introduced mice, rats, and many non-native birds, the hawks survived entirely on native prey.
Their ability to use several habitat types has helped them persist across much of Hawaiʻi Island.
Listen for their piercing calls while exploring the park’s forests and open landscapes.
🐦 Rare Birds of the Kahuku Unit
The Kahuku Unit protects important high-elevation forests on the southern slopes of Mauna Loa.
These forests provide habitat for several of Hawaiʻi’s rarest native birds.
The ʻakiapōlāʻau is one of the most unusual.
Its highly specialized bill functions almost like two tools in one. The lower bill can be used to probe or work bark, while the curved upper portion helps extract insects and spiders.
The endangered Hawaiʻi ʻākepa searches ʻōhiʻa buds, seed pods, and other vegetation for small arthropods.
Another endangered honeycreeper, the ʻalawī or Hawaiʻi creeper, moves along branches and trunks while hunting insects.
These species are much more difficult to encounter than ʻapapane or ʻamakihi.
Their survival depends heavily on protecting high-elevation native forest.
🐦 Kīpukapuaulu: One of the Best Birding Areas
Kīpukapuaulu is one of the most accessible places to look for native forest birds.
Sometimes called Bird Park, this older patch of forest is a kīpuka—an area of older terrain and vegetation surrounded by younger lava flows.
A roughly 1.2-mile loop passes through mature forest where patient visitors may encounter ʻapapane, ʻōmaʻo, Hawaiʻi ʻelepaio, Hawaiʻi ʻamakihi, and other birds.
Kīpuka habitats are particularly valuable because younger lava flows can isolate older forest patches.
These biological islands may protect native plants and animals while surrounding landscapes recover.
Walk slowly and listen.
Hawaiian forest birding is often easier with your ears than your eyes.
🌋 Wildlife Islands Surrounded by Lava
Kīpuka are among the most fascinating ecological features of Hawaiʻi Volcanoes National Park.
When lava moves around an area rather than directly over it, a patch of older land can survive as an island within a younger lava flow.
Mature trees and soil may remain intact even though the surrounding landscape has been reset to bare volcanic rock.
These refuges allow wildlife to persist.
Birds, insects, spiders, and plants living within a kīpuka can later help recolonize surrounding areas as vegetation returns.
The isolation can also influence evolution by separating populations from one another.
In this sense, kīpuka resemble the Hawaiian Islands themselves on a much smaller scale.
🌙 ʻŌpeʻapeʻa: The Hawaiian Hoary Bat
Hawaiʻi has only one surviving native terrestrial mammal: the ʻōpeʻapeʻa, or Hawaiian hoary bat.
The ancestors of these bats somehow crossed more than 2,000 miles of Pacific Ocean to reach Hawaiʻi.
That extraordinary colonization led to a population found nowhere else.
ʻŌpeʻapeʻa are nocturnal.
Rather than commonly roosting in lava tubes or caves, they generally roost in trees.
Around sunset they emerge to hunt flying insects, particularly moths.
Their Hawaiian name is often translated as “half leaf,” referring to the resemblance of an outstretched bat wing to part of a taro leaf.
Seeing one can be difficult because the animals fly quickly and are most active in fading light.
🦇 How to Look for Hawaiian Hoary Bats
The best strategy is simply to watch the sky around dusk.
Openings near forest edges can provide good visibility as bats begin feeding.
Do not expect the large numbers sometimes associated with continental bat caves. ʻŌpeʻapeʻa generally occur at relatively low densities and can easily go unnoticed.
Their flight may look erratic as they pursue insects.
Because the bats depend on trees for roosting, forest conservation is important.
Threats include habitat loss and collisions with structures such as wind turbines and fences.
Even though most visitors never see one, the presence of a native bat is one of the most extraordinary chapters in Hawaiʻi’s natural history.
🦋 Pulelehua: The Kamehameha Butterfly
Hawaiʻi’s unusual wildlife is not limited to vertebrates.
The pulelehua, or Kamehameha butterfly, is one of only two butterfly species native to Hawaiʻi and is the state’s official insect.
Adults have bright orange upper wings patterned with darker markings.
The undersides are much more subdued, helping the butterfly blend into bark and vegetation when its wings are closed.
Native insects like the pulelehua are important pollinators and members of Hawaiian food webs.
Their presence also reflects millions of years of isolation.
Many familiar insect groups arrived only after people began transporting plants, soil, cargo, and animals among islands and continents.
🕷️ Nananana Makakiʻi: The Happy Face Spider
Few spiders have a name as appealing as the nananana makakiʻi, commonly called the happy face spider.
The name comes from variable markings on the abdomen that can sometimes resemble a smiling human face.
Individual spiders may have very different patterns.
These small native spiders live among vegetation and are harmless to people.
Their extraordinary variation has made them well known among scientists interested in genetics and evolution.
Like many Hawaiian invertebrates, they demonstrate how isolation can produce unusual forms that would be easy to overlook while focusing only on larger animals.
🐛 Carnivorous Caterpillars
Hawaiʻi is even home to native caterpillars that prey on other animals.
Most caterpillars around the world feed on plants.
Certain Hawaiian species evolved a completely different strategy.
They ambush small insects and other arthropods.
This predatory behavior is exceptionally unusual among caterpillars and demonstrates the remarkable evolutionary experiments that took place in Hawaiʻi’s isolated ecosystems.
When ancestors reached the islands, ecological roles filled by other animals elsewhere were often vacant.
Natural selection could therefore push descendants in directions rarely seen on continents.
Hawaiʻi Volcanoes National Park protects numerous insects with equally unusual adaptations.
🦗 Insects on New Lava
Volcanic eruptions continually create new habitat.
At first, a fresh lava flow seems incapable of supporting wildlife.
There is little soil, limited vegetation, and few obvious food sources.
Yet insects can be among the first animals to colonize.
Certain Hawaiian crickets are associated with relatively young lava landscapes.
Wind-blown insects and organic material provide food even before substantial plant communities develop.
Over time, lichens and pioneer plants appear, followed by increasingly complex communities.
Watching life return to lava is one of the clearest ways to see ecological succession in action.
The animals living on fresh volcanic terrain are part of that process.
🐦 ʻUaʻu: The Hawaiian Petrel
The ʻuaʻu, or Hawaiian petrel, follows one of the park’s most remarkable life cycles.
These endangered seabirds spend much of their lives over the Pacific Ocean but return to high volcanic slopes to reproduce.
On Hawaiʻi Island, important nesting habitat occurs within Hawaiʻi Volcanoes National Park on Mauna Loa.
Adults return to nesting areas after dark and use underground burrows.
Parents travel between remote mountain nests and the ocean to feed.
Young birds eventually leave their burrows at night and make their first flight toward the sea.
Visitors are unlikely to see ʻuaʻu during an ordinary park trip because the birds are nocturnal and their nesting locations are carefully protected.
Their existence nevertheless connects the park’s highest volcanic landscapes directly to the ocean.
💡 Artificial Lights and Seabirds
Artificial lighting can create serious problems for young seabirds.
Fledgling petrels navigate toward the ocean at night.
Bright artificial lights can disorient them, causing birds to circle, collide with structures, or fall to the ground.
Once grounded, a seabird adapted for flight over the ocean may struggle to launch again.
It also becomes vulnerable to cats, mongooses, vehicles, and other threats.
Hawaiʻi Volcanoes National Park has modified lighting to reduce these risks.
Shielding lights and directing illumination downward helps preserve darker skies while making it less likely that young seabirds will become confused.
🐢 Honuʻea: The Hawksbill Turtle
The remote coastline of Hawaiʻi Volcanoes National Park provides habitat for one of Hawaiʻi’s rarest marine animals.
The honuʻea, or hawksbill sea turtle, is endangered.
Its pointed, hawk-like beak and overlapping shell plates help distinguish it from the more familiar green sea turtle.
Female hawksbills come ashore to lay eggs in sandy coastal habitat.
Hawaiʻi Volcanoes protects several important nesting beaches.
These areas are remote, and visitors should never seek to disturb a nesting female, eggs, or hatchlings.
Artificial lights, predators, habitat loss, marine debris, and historical hunting have all contributed to the species’ decline.
Protecting dark and relatively undisturbed coastlines is essential to its survival.
🐢 Honu: Green Sea Turtles
Green sea turtles, known as honu, are considerably more common around the Hawaiian Islands than hawksbills.
They feed largely on algae and other marine vegetation around nearshore rocks and reefs.
Visitors exploring Hawaiʻi Island’s coastline may occasionally encounter them in the water or resting along appropriate shorelines.
Even apparently relaxed turtles need space.
Do not touch, chase, block, ride, or feed them.
A resting turtle that lifts its head repeatedly or begins moving away may already be reacting to human presence.
Observe from a respectful distance and allow the animal to choose whether the encounter continues.
🐋 Koholā: Humpback Whales
During winter, enormous humpback whales migrate into Hawaiian waters from feeding grounds in the North Pacific.
Known in Hawaiian as koholā, they come to warmer subtropical waters to breed, give birth, and care for calves.
The main Hawaiian whale season generally begins in late fall and continues through spring.
Hawaiʻi Volcanoes National Park’s rugged coastline can provide occasional opportunities to spot distant whales offshore.
A visible blow, splash, or raised tail may be the first indication that whales are present.
Binoculars are useful.
The animals may be far from shore, and responsible wildlife watching never requires trying to approach them from dangerous coastal cliffs.
🐦 Koaʻe Kea: White-Tailed Tropicbirds
White-tailed tropicbirds, known as koaʻe kea, add an unmistakably tropical element to the park’s birdlife.
These elegant white seabirds have long, narrow tail streamers and often nest on cliffs or other steep terrain.
Visitors may see them gliding above volcanic craters and coastal landscapes.
Their effortless-looking flight contrasts dramatically with the dark lava beneath them.
Although they feed at sea, nesting brings the birds inland to protected rocky sites.
Watching a bright white tropicbird cross the enormous crater of Kīlauea can be one of the park’s most memorable wildlife moments.
🐦 Native Birds vs. Introduced Birds
Not every colorful bird in Hawaiʻi Volcanoes is native.
Visitors may encounter Japanese white-eyes, northern cardinals, kalij pheasants, house sparrows, red-billed leiothrix, and other species introduced to Hawaiʻi by people.
Some are attractive and enjoyable to watch.
Ecologically, however, introduced species can compete with native birds, spread invasive plant seeds, or contribute to disease transmission.
Learning to distinguish native from introduced wildlife makes birdwatching in Hawaiʻi considerably more meaningful.
A crimson ʻapapane feeding in an ʻōhiʻa tree represents millions of years of Hawaiian evolution.
A cardinal, however beautiful, represents a much more recent arrival.
🐗 Feral Pigs
Feral pigs are among the most damaging introduced animals in Hawaiian forests.
Pigs root through soil and vegetation while searching for food.
That disturbance destroys native plants and creates openings where invasive species can establish.
Their wallows and rooting can also create pools of standing water suitable for mosquitoes.
This adds another connection between invasive mammals and native bird decline.
By creating mosquito habitat, pigs can indirectly increase the threat of avian malaria.
The park uses fencing and other management techniques to keep pigs out of sensitive native ecosystems.
Removing invasive animals is difficult, but forest recovery can be dramatic once repeated disturbance stops.
🐈 Feral Cats
Feral cats are highly effective predators.
Native Hawaiian birds evolved without mammalian predators like cats and often lack defensive behaviors that continental birds developed.
Ground-nesting and burrow-nesting species are particularly vulnerable.
Cats can kill adult birds, chicks, and other native animals.
They are an especially serious threat to seabirds such as ʻuaʻu.
Keeping pet cats indoors outside the park is one simple way residents can contribute to Hawaiian wildlife conservation.
Inside protected areas, controlling feral predators remains an important part of preventing additional native species from disappearing.
🐾 Mongooses
Mongooses were introduced to Hawaiʻi during the 19th century in an unsuccessful effort to control rats in sugarcane fields.
The plan failed spectacularly.
Rats are largely active at night, while mongooses tend to be active during the day.
Instead of eliminating rats, Hawaiʻi ended up with two introduced predators.
Mongooses consume bird eggs, chicks, reptiles, insects, and other animals.
Ground-nesting nēnē are particularly vulnerable.
Visitors sometimes see mongooses darting across roads or through vegetation.
Although they may look interesting, their presence represents one of the most damaging ecological mistakes in Hawaiian history.
🐐 Goats and Other Grazing Animals
Goats, cattle, sheep, and other hoofed animals introduced by people have dramatically changed Hawaiian ecosystems.
They browse and trample native vegetation, accelerate erosion, and help invasive plants spread.
Goats once caused particularly severe damage in parts of Hawaiʻi Volcanoes National Park.
Fencing and long-term removal efforts have substantially reduced their presence inside protected areas.
The recovery of vegetation after removal demonstrates how strongly large introduced herbivores can reshape an island ecosystem.
Healthy native vegetation provides the foundation for much of the park’s native wildlife.
Protecting birds and insects therefore often begins with protecting plants.
🔥 Wildfire and Wildlife
Wildfire presents another growing challenge.
Many native Hawaiian ecosystems did not evolve with the frequent fire regimes found in some continental landscapes.
Introduced grasses can create continuous dry fuel that allows fire to spread rapidly.
After fire, invasive grasses may return faster than native shrubs and trees.
That creates even more fuel for future burns.
The result can be a self-reinforcing cycle that gradually converts native habitat into invasive grassland.
For wildlife dependent on ʻōhiʻa forest, native shrubland, or other specialized habitats, repeated fire can be devastating.
Preventing human-caused ignitions is an important part of protecting native wildlife.
🌡️ Climate Change and Native Species
Climate change affects Hawaiʻi Volcanoes wildlife in several ways.
Warmer temperatures can allow mosquitoes and avian malaria to spread into higher elevations that once served as refuges for native forest birds.
Changes in rainfall may alter flowering, fruiting, forest health, and freshwater availability.
Sea-level rise threatens coastal habitat, including nesting beaches used by sea turtles.
Warmer oceans affect marine ecosystems.
Wildfire risk can also increase under hotter and drier conditions.
Species already restricted to small ranges have little room to move when environmental conditions change.
Protecting large landscapes from sea level to mountain summit gives wildlife the best possible opportunity to adapt.
🔭 Best Places to Look for Wildlife
There is no single wildlife-viewing area because species occupy very different habitats.
Kīpukapuaulu is one of the best accessible choices for native forest birds.
Mauna Loa Road passes through high-elevation forests where birds such as ʻapapane, ʻiʻiwi, ʻamakihi, ʻōmaʻo, and ʻelepaio may occur when access is open.
Crater Rim Drive and surrounding areas can be productive for nēnē and native birds.
Kahuku protects important high-elevation habitat and is particularly significant for rare native forest species.
Chain of Craters Road crosses an enormous elevation range and provides opportunities to watch habitat change all the way toward the coast.
Wherever you go, early morning is generally best for forest bird activity.
🌅 Listen to the Dawn Chorus
Hawaiian forests can be at their most memorable around sunrise.
At places such as Kīpuka Kī, dozens of native birds may begin calling as the forest brightens.
ʻApapane can dominate the chorus, accompanied by Hawaiʻi ʻamakihi, ʻōmaʻo, ʻelepaio, and other birds.
Learning calls before a visit greatly improves wildlife watching.
Dense foliage can make small forest birds difficult to see, but their songs may reveal exactly where to look.
Standing quietly and listening is often far more effective than walking quickly through the forest.
Hawaiʻi’s wildlife rewards patience.
🔭 Bring Binoculars
Binoculars are one of the most useful things wildlife watchers can bring to Hawaiʻi Volcanoes.
Forest birds frequently remain high in ʻōhiʻa canopies.
Nēnē should be observed from a distance.
Tropicbirds may cross craters far below an overlook.
Sea turtles and whales can be hundreds of yards offshore.
Binoculars allow visitors to see natural behavior without approaching animals closely.
For birdwatchers, lightweight binoculars are generally more practical than extremely high magnification because native forest birds move quickly through vegetation.
🚫 Never Feed Wildlife
Feeding wildlife causes serious problems.
Nēnē are particularly vulnerable because they can quickly learn to associate people and cars with food.
Birds that begin visiting roads and parking areas face a much higher chance of being struck by vehicles.
Human food can also provide poor nutrition and change natural feeding behavior.
The same principle applies to every wild animal in the park.
Do not feed birds, mongooses, cats, or any other wildlife.
Allow native animals to obtain food from the ecosystem they evolved to use.
📏 Give Wildlife Space
Native Hawaiian wildlife often evolved without large terrestrial predators and may appear unusually tolerant of people.
That should never be interpreted as permission to approach.
As a general wildlife-watching practice, use binoculars or a telephoto lens and allow animals to control the distance.
Nēnē deserve especially careful treatment during nesting season.
Current park messaging asks visitors to stay at least 60 feet away from nēnē and to give them even more room when they are nesting, caring for goslings, or reacting to people.
Never block an animal’s direction of travel.
If wildlife changes its behavior because of your presence, create more distance.
🚗 Drive Slowly
For some park wildlife, road safety is literally a matter of survival.
Nēnē frequently forage beside roads and cross pavement.
They can be especially difficult to see around dawn, dusk, or during rain and fog.
Follow posted speed limits.
Slow down immediately when wildlife warning signs are present.
Avoid stopping in the middle of a traffic lane for photographs.
If birds are beside the road, continue cautiously rather than encouraging them to remain near cars.
A few extra minutes of driving time can save the life of an endangered or threatened animal.
🐕 Pets and Native Wildlife
Hawaiʻi Volcanoes has much stricter pet regulations than many visitors expect.
Pets are prohibited on the park’s frontcountry and backcountry hiking trails and throughout undeveloped wilderness areas.
They are permitted only in certain developed locations and designated roads and parking areas when properly leashed.
These restrictions protect native wildlife.
Dogs can chase, stress, injure, or kill nēnē and other animals even when owners believe their pet is friendly.
Visitors traveling with a dog should check current park rules carefully before planning hikes.
🌋 Wildlife in a Constantly Changing Landscape
One thing separates Hawaiʻi Volcanoes from nearly every other wildlife destination: the habitat itself can disappear beneath lava.
An eruption can cover forest, grassland, roads, and animal habitat within hours or days.
At first, the new landscape may appear lifeless.
Then colonization begins.
Wind carries insects and seeds.
Birds cross the barren terrain.
Lichens establish on rock.
Ferns, shrubs, and eventually trees take root in favorable cracks and depressions.
Older forest preserved within kīpuka can help life return to surrounding lava flows.
Wildlife in Hawaiʻi Volcanoes exists in a landscape where ecological destruction and creation are both natural parts of the volcanic cycle.
🌎 Why Hawaiʻi Volcanoes Wildlife Matters
Hawaiʻi Volcanoes National Park protects far more than spectacular craters and active lava landscapes.
It is one of the most important refuges for Hawaiian biodiversity.
Nēnē recovering from near extinction, ʻiʻiwi surviving in cool high-elevation forest, rare honeycreepers protected in Kahuku, ʻuaʻu nesting on volcanic slopes, hawksbill turtles using isolated beaches, and ʻōpeʻapeʻa flying through the evening sky all depend on habitats within this enormous protected landscape.
Their survival is not guaranteed.
Introduced predators, disease, habitat loss, invasive species, wildfire, vehicle strikes, and climate change continue to reshape the ecosystem.
The good news is that conservation works.
Nēnē recovery demonstrates what sustained management can accomplish. Predator control protects nests. Fences keep destructive hoofed animals away from native forest. Habitat restoration allows native plants to return.
For visitors, the most important contribution is simple: watch carefully, stay on trails, never feed wildlife, drive slowly, respect closures, and give every animal space.
Hawaiʻi’s wildlife evolved through millions of years of isolation.
Seeing these species in the volcanic landscapes where they belong is one of the most extraordinary experiences Hawaiʻi Volcanoes National Park can offer.
