(ALAKA‘I PLATEAU, KAUA‘I) – From a remote camp, perched on a narrow 3,000-foot cliff, near the top of Wainiha Valley, Justin Hite, and his team from the Kaua‘i Forest Bird Recovery Project (KFBRP), are in the midst of another field season. A season, that is probably the last for the diminutive native Hawaiian honeycreeper, the ‘akikiki.
“This is one of the last places where we’re still seeing a ton of native forest birds, where everywhere else, just in the last couple of years they’ve quickly and suddenly vanished. And we think it’s because of mosquitoes,” Hite explained during a recent eight-day-long egg collection trip.
The usually upbeat and hopeful KFBRP Field Supervisor has lost some of his optimism this season, as before their very eyes he and his crew are likely seeing the last ‘akikiki remaining in the wild. It’s not unexpected, as other members of KFBRP have been documenting increases of disease-carrying mosquitoes on the plateau.
Regulators are on the verge of approving landscape control of mosquitoes in the mountains of Kaua‘i using the Incompatible Insect Technique (IIT), to reduce the likelihood that forest birds will be impacted by avian malaria, carried by female mosquitoes.
While permitting and approval is underway, the KFBRP team continues work in what is arguably some of the toughest terrain around.
Robby Kohley, Director of Aviculture with Pacific Rim Conservation, is the on-site expert working with the forest bird team in the Mohihi region of the plateau.
He’s worked across the Hawaiian Islands and in Alaska and commented, “Each project comes with a different set of challenges. The logistics problems of this project are quite high. Between the weather (mostly wet, muddy, and incredibly steep), and the lack of luck ‘akikiki are having with nests this year, I’d say this one ranks really high on the challenge scale.”
Since late January the recovery teams have been flying into the field, hiking to field camp, and then from there trudging through knee deep mud on unimproved pig trails to reach ‘akikiki nests that had been previously spotted.
Using a camera, mounted on a long pole, they’re able to see the condition of the tiny eggs. If they appear to be in good shape, they then rig up a tethered ladder system to get a team member high into the forest canopy to collect eggs. They’ll climb as high as 48-feet to get them.
So far, they’ve successfully rescued ten ‘akikiki eggs that are placed in a portable incubator and carried, ever so gently, up the trail to camp. They’re then flown out to a brooder house in Koke‘e State Park and then eventually to the San Diego Zoo Wildlife Alliance Keauhou Bird Conservation Center at Volcano.
Hite notes ‘akikiki in the wild are very good at breeding. However, if avian malaria doesn’t strike them down first, rats are picking them off one-by-one.
“This year is an out-of-control level of nest failures,” Hite explained. Typically, the team finds 30 nests each season and almost all of them would fledge young into the wild. “We spotted a female ‘akikiki sitting on two eggs and when we came back two days later to collect the eggs, we found broken, rat-chewed eggshells on the ground.”
Now the field team has the added pressure of trying to control the rat population by setting out dozens of rat traps. If it’s not one thing it’s another and such is the trial and error, learn as you go attitude necessary to do this kind of work.
Adding to the mental, emotional, and physical stress these dedicated and passionate folks face daily, is the opposition to IIT from a small number of opponents.
At the end of a recent eight-day stint in the field he observed, “These birds are only here. They’ve been here the whole time, long before people arrived in the islands. They’re quiet, unassuming, and wonderful. If we lose them, it’s a huge loss, it’s terrible.”
Clearly the human dimension of the fight to save ‘akikiki and other native forest birds is critical. Watch the short video, Saving ‘Akikiki – The Field Team Presses On, at the link below.

Kumu and haumana of Ka ‘Imi Na‘auao O Hawai‘i and staff and volunteers from the Kaua‘i Forest Bird Recovery Project held its annual Hawaiian blessing for the 2023 field season on Feb. 2, the state Department of Land and Natural Resources said.
The blessing featured songs and dances to invoke the protection and goodwill of the gods and the elders for Kaua‘i’s native forest birds and their habitat.
Of the eight remaining forest bird species on Kaua‘i, at least two species of Hawaiian honeycreepers face imminent extinction. The ‘akikiki and ‘akeke‘e are threatened by mosquito-borne avian malaria.
Warmer climates during recent years have allowed nonnative mosquitoes to move to higher elevations, increasing the risk of disease to native forest birds. During this field season, the recovery project will collect as many of the remaining ‘akikiki as possible and place them under human care until mosquito control efforts can be implemented to ensure their survival in the wild.
“Kaua‘i’s forest birds are disappearing right in front of our eyes,” the recovery project said. “Five of the 13 species have vanished in the past 40 years, and three others, including the puaiohi, ‘akikiki and ‘akeke‘e, are critically endangered. Species disappeared with no records of song, behavior or appearance, making this loss even more devastating not only to scientists, conservationists and cultural practitioners, but to all of us.”
Forest bird recovery projects are a collaboration between the state Department of Land and Natural Resources Division of Forestry and Wildlife and the University of Hawai‘i Pacific Cooperative Studies Unit

According to a recent press release from the DLNR, another ʻAkikiki has been recovered from the forest, deep within the ʻAlakai Plateau. The ʻAkikiki rescue missions began last December when it was discovered that only a handful of ʻAkikiki remain in the wild. The rapid decline of this species has been blamed on mosquitos carrying the vector for avian malaria. The situation is so dire that without intervention, the species faces imminent extinction in the wild.
Over the Labor Day weekend a team of scientists from KFBRP, Maui Forest Bird Recovery Project (MFBRP), DLNR/PCSU along with bird care expert Peter Luscomb, captured the ʻAkikiki lovingly named “Carrot” for its orange leg bands, and transported him to the Maui Bird Conservation Center (MBCC). The Center is operated by the San Diego Wildlife Alliance.
“Carrot” is the father of “Erica” who was captured last December. The 37 captive ʻAkikiki are being held at MBCC in an effort to protect them from avian malaria. The rescue mission is part of a more extensive multi-agency plan to address the mosquito issue in critical forest bird habitat, in order to set-back the extinction clock for this species.
You can see a video of the rescue mission below.

The Hawaiian Islands are full of astounding beauty and an incredible diversity of plants, insects, and birds. Most people picture the islands—one of the most isolated archipelagoes in the world—as a tropical paradise. However, Hawai‘i’s wildlife and ecosystems have suffered tremendously from invasive species, as well as habitat destruction and degradation, particularly in the lower elevations where most people live. The majority of plants and animals in these lowland regions are non-native: they arrived with humans and displaced native Hawaiian species.

Hawaiian birds—particularly the honeycreepers, a group of small, brightly colored birds—have been devastated by non-native species. Hawaiian honeycreepers are found nowhere else in the world, and are critical components of forest ecosystems and Hawaiian culture. They are internationally renowned for their incredible diversity of bills, foraging styles, and plumage (greater diversity even, than that found in Darwin’s Galapagos finches), which occurred after their arrival in Hawai‘i approximately 5.7 million years ago, when the oldest of the main Hawaiian islands, Ni‘ihau, was forming.
Over 115 endemic bird species thrived in Hawai‘i before humans arrived, with whole groups that are now absent, including moa-nalos, flightless rails, stilt-owls, and a blind mole duck. Since human colonization, at least 71 bird species in Hawai‘i have become extinct. Historically, at least 57 species of honeycreepers filled Hawaiian forests from the sea to the mountains with their songs. Today, only 17 honeycreeper species remain, many of them on the brink of extinction. Eleven are listed as endangered or threatened under the US Endangered Species Act, and the International Union for Conservation of Nature lists 15 as vulnerable or worse.
The biggest threat to the honeycreepers’ survival is introduced diseases—specifically, avian malaria, which is transmitted by non-native southern house mosquitoes. This mosquito species arrived in 1826 and quickly spread across the islands, while avian malaria reached Hawai‘i in the early 1900s. A wave of honeycreeper extinctions soon followed. Most honeycreepers have no resistance to the disease, so one bite from an infected mosquito can be enough to kill some birds—such as the iconic ‘i‘iwi, with its brilliant scarlet feathers, black wings, and long, salmon-colored sickle bill. Both mosquitoes and the malaria pathogen require warm temperatures to reproduce, so their range has historically been limited to the lowlands (a.k.a. the mosquito zone), while most honeycreepers found refuge in cooler, high-elevation forests. The high mountains of Kaua‘i, Maui, and Hawai‘i provided significant forested area above the mosquito zone and therefore retained many of their native birds, while the lower islands tragically did not.

Unfortunately, the mosquito zone has been expanding because of increasing regional temperatures due to global climate change. Now, these invasive insects are present year-round in many formerly safe Kaua‘i and Maui forests, and honeycreeper populations are crashing as a result. Without action, the ‘akikiki and ‘akeke‘e on Kauai and the kiwikiu and ‘ākohekohe on Maui are likely to go extinct in the next decade. The ‘akikiki is at greatest risk—it could vanish within two years. From 2015 to 2021, the number of ‘akikiki breeding pairs in the core of their range decreased from 35 to 1, and the entire wild population is now estimated at fewer than 76 birds (and likely closer to 45). Soon, the rest of the honeycreepers—including those on Hawai‘i Island, where higher mountain forests have provided more protected, disease-free areas—will suffer the same mosquito-driven population collapse seen on Kaua‘i.
Yet there is hope, because we have the ability to save these irreplaceable treasures of cultural and biological diversity. Birds, Not Mosquitoes (BNM), a collaboration of over 20 state, federal, and nonprofit partners and dozens of individuals, is working to deploy what is known as an “incompatible insect technique”—a form of mosquito birth control that conservation practitioners and agency biologists agree is the most promising approach to suppress mosquito populations and save these native birds. It involves a very common, naturally occurring bacteria, Wolbachia, that affects mosquitoes’ ability to reproduce. For mosquitos to produce viable eggs, both the male and female must carry the same strain of Wolbachia. To control populations, scientists will rear males that carry a different strain of the bacteria than is found in wild mosquitoes, then release the lab-reared mosquitoes into forests in Hawai‘i. Male mosquitoes do not bite birds (or people!), but very effectively find and mate with wild females. Because the bacteria strains are incompatible, females mated to lab-reared males will lays eggs that do not hatch. After several releases, the mosquito population will decline due to this lack of successful reproduction.
Millions of lab-reared males would be released to outnumber the wild males and increase the likelihood that incompatible males will mate with the wild females. Population suppression would be achieved by repeating this weekly or monthly, depending on the situation. Because mosquitoes are such recent arrivals to Hawai‘i, none of the native species depend on them, so removing them should not significantly impact food webs. Mosquito birth control was originally developed and deployed to control diseases affecting humans, and this safe and proven technique has been used to suppress various mosquito species worldwide, including in Fresno County, California, and Miami-Dade County, Florida.
BNM is building upon that investment and research to launch the first application of this mosquito suppression method for wildlife conservation purposes. We are working on all components of this project to advance it as quickly as possible. Wolbachia mosquitoes are regulated as a biopesticide by the US Environmental Protection Agency and the state Department of Agriculture. We are securing the required permits, completing the necessary environmental assessments for Kaua‘i and Maui, and conducting extensive community engagement about this project across the islands.

BNM partners are also researching ways to construct the best implementation plan for location and frequency of releases. The males only live a few days and do not reproduce, so many releases each year will be needed to maintain protection of the birds’ habitat from the remnant wild population and any female mosquitoes that move into the forest from the lower elevations. While this does increase the costs, it also means the process is reversible, and if there are unforeseen consequences, stopping the releases will allow the system to return to its previous state. The current timeline is to begin field tests and pilot releases in 2023, and effective landscape-scale control of mosquitoes in 2024. Although complicated, all these individual steps have been done elsewhere, so we are confident we can combine everything to save our honeycreepers.
AWI is a key part of BNM’s strategy to save the Hawaiian honeycreepers from extinction and has provided support for Kaua‘i Forest Bird Recovery Project surveys to better understand mosquito distribution. This will help BNM determine release frequency and locations, monitor and assess mosquito population reductions, and adaptively adjust deployment once started. AWI has also supported the American Bird Conservancy’s community engagement activities. The mosquito birth control project will be an extensive management action on multiple islands, using a technique new to Hawai‘i. Because honeycreepers are uncommon to extremely rare and found in remote areas, most people—even those who live in Hawai‘i—are unfamiliar with them. Inspiring people and connecting them to the need to save these species is critical to building the public support necessary for the project to succeed.
The success of this project will prevent additional extinctions of Hawaiian birds and help populations of these birds to rebound, providing opportunities for everyone to see and experience these precious beings of the Hawaiian Islands.

According to a press release issued by the U.S. Department of the Interior (DOI), a significant amount of federal funding will be sent to Hawaiʻi to help address the extinction crisis facing at least four species of native Hawaiian birds, including Kauaʻi’s ʻakikiki and ʻakekeʻe.

A few weeks ago staff members, Hannah Landwerlen and Evan checked a Puaiohi nest that they have been monitoring in the Alaka’i and found that the nestling and the female were killed by a predator. When Field Leader, Justin Hite first started this job in 2015, he went to check that same nest and also found the female torn to pieces. These kind of events are particularly hard for the staff at KFBRP, because their positions here are way more than just jobs.

In a recent DLNR Press release (below) and news conference (video below), experts discuss the extinction crisis faced by some of Hawai’i’s rarest forest birds. A report was presented to decision makers offering a selection of actions to address the current crisis. Also included in the report are conservation strategies for other species. Experts warn that if no action is taken four species of forest birds would face extinction within 1-10 years and as many as 11 additional extinctions would occur in the next decade.
