2024 is Ka Makahiki o Nā Manu Nahele: The Year of the Forest Birds

2024 is Ka Makahiki o Nā Manu Nahele: The Year of the Forest Birds, a time to celebrate the jewels of our Hawaiian forests. Our native forest birds are uniquely Hawaiian: they exist only in the Hawaiian Islands and nowhere else in the world. These birds have critical ecological roles as pollinators, seed dispersers, and insect managers of Hawaiian forests. Our forest birds are an inextricable part of Native Hawaiian culture in their roles as ʻaumakua (family deities) and messengers between akua (gods) and kānaka (people). Nā manu nahele are celebrated in mele (songs) moʻolelo (stories), ʻōlelo noʻeau (proverbs), kaʻao (legends), and in the creation of feather adornments including lei hulu.

Our nā manu nahele are at risk: of 84 forest bird species known from either the fossil record or human observation, an astonishing 58 species have gone extinct. Of the 26 species that remain today, 24 are listed by the International Union for the Conservation of Nature as vulnerable, near-threatened, threatened, endangered, or critically endangered, including the ʻio seen here (PC: Bret Mossman). To learn more about why Hawaiʻi has lost so many native birds and what is being done to save those that remain, explore below and come to one of our Makahiki o Nā Manu Nahele events this year to meet the manu experts who help prevent extinction.

Makahiki o Nā Manu Nahele is brought to you by a partnership of manu enthusiasts from DLNR Forestry & Wildlife, Kamehameha Schools, Kauaʻi Forest Bird Recovery Project, Maui Forest Bird Recovery Project, the ʻAlalā Project, the University of Hawaiʻi Rapid ʻŌhiʻa Death outreach group, Bishop Museum, US Fish & Wildlife Service, Birds Not Mosquitoes, the Coordinating Group on Alien Pest Species, the Invasive Species Committees, Hawaiʻi Association of Watershed Partnerships, and the Nature Conservancy of Hawaiʻi.

Resisting extinction – THE NEXT TOOL FOR SAVING KAUA‘I FOREST BIRDS FROM EXTINCTION INTRODUCED

(KOKE‘E-WAIMEA CANYON STATE PARK, KAUA‘I) – A dozen researchers and technicians last week began releasing incompatible male mosquitoes to try and stop the near-certain extinction of at least four species of Native Hawaiian honeycreepers. A first for Hawai‘i, the release took place just off a road on the Alaka‘i Plateau on Kaua‘i.

The release of 20,000 male mosquitoes is a pilot study. The day was tinged with excitement and no small measure of emotion, as many of the people involved have been working to save the honeycreepers and studying mosquitoes’ impact on them for more than a decade.

Female mosquitoes that carry avian malaria are moving higher and higher into honeycreeper habitat as temperatures warm. Previously, the region was too cold for mosquitoes. Now, they are transmitting avian malaria, which kills many honeycreepers rapidily, in the forests that were once the birdsʻ last refuge. One species, the ʻakikiki, has declined to as few as five or six individual birds living in the wild.

Dr. Cali Crampton, Project Leader of the Kaua‘i Forest Bird Recovery Project (KFBRP) said, “I’m both sad and excited at the same time. Sad to know that our forest birds are suffering so greatly from these mosquito-borne diseases. But, after years of trying everything we can to save them from extinction, it’s a relief to know that we are at the cusp of launching a tool that can reverse those declines.”

The tool or technique is known as IIT, for Incompatible Insect Technique. Thursday’s releases are part of a pilot study and will inform the wider scale applications of IIT aimed at reducing mosquito populations in bird habitat.

The day began with two team members retrieving two large, cardboard boxes at the airport holding pods containing incompatible male Culex mosquitoes. The materials were examined by the Hawai‘i Department of Agriculture.

After a quick stop to drop a small number of mosquitoes at the DLNR Division of Forestry and Wildlife (DOFAW) base yard in Līhu‘e, to act as data control for the insects being released in the forest, the entire team gathered in a small clearing in Koke‘e, laid a plastic tarp on the ground, and arranged 20 pods in preparation to release the male mosquitoes.

The team had already strung up what they call a bug dorm, a rectangular mesh enclosure which is the center of a longevity trial, to see how the male mosquitoes will survive after being released. Dozens of traps, surrounding the release site, are already in place. Over the next week the bug dorm and the traps will be checked regularly.

Bryn Webber, KFBRP Mosquito Research Coordinator, explained, “We’re looking at collecting data on how far they travel through the forest and how long they live. That information will be used for landscape-level releases to help determine how many pods to use and how the mosquitoes disperse across the landscape.”

Each pod holds 1,000 mosquitoes and once uncovered, most of them immediately fly away. It’s a little challenging avoiding the tendency to swat at them. But, no one got a single mosquito bite, because male mosquitoes are not able to bite.

Crampton is wearing one of her organizationʻs shirts which says, “Save a Bird, Swat a Skeeter.” She laughs, “I’m definitely not swatting any skeeters today because these mosquitoes are the savior mosquitoes. These incompatible males will breed with females on the landscape and prevent successful fertilization, so no second generation and no more eggs, causing their population to decline.”

The team is unified in its message, reminding people that male mosquitoes don’t bite, so they don’t spread diseases in birds or people.

Mele Khalsa, Natural Resource Manager on Kauaʻi with The Nature Conservancy, Hawaiʻi and Palmyra, commented, “Avian malaria is only carried by one species of mosquito, the female Culex quinquefasciatus, or Southern House mosquito. They are the only vector for this deadly disease of our avian friends, so we’re just looking to prevent the spread of this one mosquito.” She added this is not a ‘one and done’ project and will continue until mosquitoes are suppressed in honeycreeper habitats.

Allison Cabrera, with the Pacific Cooperative Studies Unit, spent the last three years in the field preparing for this day. She summed up the group’s feelings, “This is huge. We’ve done so much work and spent so much time to get to this point. It’s so exciting. We’re here finally. It’s great and it feels wonderful.”

Wildlife conservation agencies (state and federal) are one step closer to protecting forest birds from mosquito-borne diseases in Kauaʻi

HONOLULU — The Hawaiʻi Department of Land and Natural Resources (DLNR) and U.S. Fish and Wildlife Service (USFWS) are one step closer to protecting forest birds from mosquito-borne diseases in key high-elevation native forest bird habitat on Kauaʻi, with their proposal to employ Incompatible Insect Technique (IIT) to reduce mosquito populations. A jointly prepared Environmental Assessment (EA) has been finalized and issuance of a finding of no significant impact (FONSI) at the state and federal levels.

 

Introduced diseases, particularly avian malaria spread by invasive mosquitoes, are the greatest threat to forest birds.  Just one bite can kill a forest bird. Implementing mosquito control is urgently needed to prevent extinction of Hawai‘i’s forest birds and is part of the U.S. Department of the Interior’s Hawaiian Forest Bird Keystone Initiativeand supported with Bipartisan Infrastructure Law funding.  The DOI offices and bureaus, working alongside the DLNR, the Native Hawaiian community, and many public and private partners are leading a comprehensive initiative to prevent extinction of additional Hawaiian forest birds. The use of IIT mosquito control is a critical component of a multi-pronged initiative and the DOI Strategy for Preventing the Extinction of Hawaiian Forest Birds.

 

IIT is a way to control insect pests, like mosquitoes, without using harmful chemicals. In Hawaiʻi, this technique involves releasing male mosquitoes that carry a different, incompatible strain of bacteria (Wolbachia) than what is present in the wild mosquito population. When these incompatible male mosquitoes mate with the wild female mosquitoes, the resulting eggs do not hatch, decreasing the mosquito population over time. This approach does not employ genetic engineering and does not involve or result in the genetic modification of either mosquitoes or bacteria.

 

“Already, 10 of the 16 native honeycreepers of Kaua‘i have gone extinct, and three of the remaining six species are endangered or threatened, with research documenting that the ʻakeke‘e and ʻakikiki would be driven to extinction within the next decade unless immediate action is taken.”, said Earl Campbell, U.S. Fish and Wildlife Service field supervisor for the Pacific Islands Fish and Wildlife Office; “The Service’s purpose and need for the project is an urgent matter and directly supports DOI’s strategy that contributes to the recovery and conservation of several federally listed species, including the ‘akeke’e, ‘akikiki, puaiohi, and ‘i’iwi, as well as other avian species with concerning declines in population and range.”

 

The Service and DLNR jointly produced the draft EA, released on June 23, 2023, for a 31-day commenting period that concluded on July 24, 2023. On July 11, 2023, the Service, DLNR, and their partners, held an open house on Kauaʻi to dialogue with members of the community, receive public comments, and answer questions.

 

On September 22, 2023, the Service issued a FONSI to conclude the National Environmental Policy Act process and document the decision of the final EA. A FONSI is issued when environmental analysis and interagency review during the EA process find a project to have no significant impacts on the quality of the environment. The statements and conclusions reached in the FONSI are based on documentation and analysis provided in the final EA.

 

The DLNR, a cooperating agency on this project, has prepared its own finding covering actions on state-managed lands and private lands within the project area. Today, the  Hawai‘i Board of Land and Natural Resources approved and issued a State FONSI, which concludes the Hawai‘i Environmental Policy Act process and enables DLNR to move forward with IIT mosquito control on State lands.

 

“Native honeycreepers like the ‘akikiki have literally crashed in their native habitats in the montane regions of Kaua‘i. The latest surveys conducted by the Kaua‘i Forest Bird Recovery Project, only detected five remaining ‘akikiki in the wild,” said DLNR Division of Forestry and Wildlife Administrator David Smith.

 

Hawaiʻi’s native forest bird species have undergone precipitous declines and extinctions since the arrival of humans to the archipelago, particularly Europeans; 39 of the 56 native Hawaiian honeycreepers have gone extinct and 11 of the remaining 17 species are endangered or threatened. Although several factors have led to declines of these remaining species, the main threat to Hawaiian honeycreepers is currently avian malaria (Plasmodium relictum) and avian pox (Avipoxvirus spp.); nonnative diseases that are principally spread by the nonnative southern house mosquito (Culex quinquefasciatus). Until recently, there were no viable means available to control mosquito vectors at the landscape scale within natural areas in Hawaiʻi.

 

The DLNR manages 22 natural areas comprising the most intact habitats on Kauaʻi with the intent of safeguarding these habitats and species, as well as the cultural heritage associated with them. The proposed project would occur on approximately 59,204 acres (23,959 hectares) of forest reserves, state parks, and private lands in the Kōkeʻe and Alakaʻi Wilderness areas of Kauaʻi. This project is consistent with the statutory missions and responsibilities of the Service and DLNR.

Action Alert | Submit testimony for OCTOBER 13 BLNR Meeting

Share your manaʻo by THIS THURSDAY, 10/12 on the Final Kauaʻi EA with the BOARD OF LAND AND NATURAL RESOURCES

Aloha, friends of our nā manu nahele,

On October 13, 2023, the Department of Land and Natural Resources-Division of Forestry and Wildlife (DLNR-DOFAW) will be requesting the Board of Land and Natural Resources to approve the Final Environmental Assessment (EA) titled “Final Environmental Assessment for Use of Wolbachia-based Incompatible Insect Technique for the Suppression of Non-native Southern House Mosquito Populations on Kauaʻi”. DLNR-DOFAW prepared this Final EA with the US Fish and Wildlife Service (USFWS) as a cooperating agency.

DLNR-DOFAW requests the Board approval of this Final EA and authorization for the Chairperson to issue a Finding of No Significant Impact (FONSI) for this effort to stabilize and recover populations of critically endangered Hawaiian forest birds on the island of Kauaʻi.

To prevent the extinction of Kauaʻi’s nā manu nahele, we, together with DLNR-DOFAW and the numerous partners within Birds, Not Mosquitoes are proposing to control invasive mosquitoes that spread diseases like bird malaria. Mosquito control would be implemented on a landscape level in critical forest bird habitats in Kauaʻi.

Send an email to  blnr.testimony@hawaii.gov for written testimony or find instructions for oral testimony here: https://dlnr.hawaii.gov/meetings/blnr-meetings-2023/

Mahalo nui for raising your voice for nā manu nahele.

ALL HANDS EFFORT TO SAVE KAUAʻI BIRDS FROM EXTINCTION

Bird experts on Kauaʻi are using all the tools in their toolbox to keep critically endangered forest birds from going extinct. One honeycreeper species, ʻakikiki, could disappear from the wild this year due to mosquito-borne avian malaria, with another species, ʻakekeʻe, not far behind. Warmer climates in recent years have allowed invasive mosquitoes to move to higher elevations, increasing the risk of disease to native forest birds. While conservation partners wait for final approval of a proposed mosquito birth control, also known as the Incompatible Insect Technique (IIT), they are stepping up their use of other, more traditional tools to give the birds a lifeline. 

Hawaiian Honeycreeper Celebration Day 8.08 Designated by Hawaii Legislature

After multiple rounds of testimony from students across the state, the Hawaii State Legislature designated 8.08 as Hawaii Honeycreeper Celebration Day. Events to celebrate our honeycreepers are taking place across the state this month. For a full list of events, you can check out the event listing on the Birds Not Mosquitoes website, where you can also learn more about the testimony given by our own Kaua’i students.

ALL HANDS EFFORT TO SAVE KAUAʻI BIRDS FROM EXTINCTION

Bird experts give honeycreepers a lifeline while waiting for mosquito birth control

Bird experts on Kauaʻi are using all the tools in their toolbox to keep critically endangered forest birds from going extinct. One honeycreeper species, ʻakikiki, could disappear from the wild this year due to mosquito-borne avian malaria, with another species, ʻakekeʻe, not far behind. Warmer climates in recent years have allowed invasive mosquitoes to move to higher elevations, increasing the risk of disease to native forest birds. While conservation partners wait for final approval of a proposed mosquito birth control, also known as the Incompatible Insect Technique (IIT), they are stepping up their use of other, more traditional tools to give the birds a lifeline.

August 8 is legislatively designated as Hawaiian Honeycreeper Day, and it’s the day the team from the Kauaʻi Forest Bird Recovery Project (KFBRP) is taking to the skies to expand use of two naturally-occurring bacteria, Bacillus thuringiensis (sold commercially as “Dunk”) and Bacillus sphaericus, to prevent mosquito larvae from hatching in the uplands of Kauaʻi.

These bacteria are harmless to humans but deadly to mosquito larvae. They’re found in soil worldwide, and are widely used in organic agriculture and water treatment. While project staff have used Bacillus to control mosquito larvae for years, it has traditionally been applied by hand while hiking across the many streams and valleys of the Alakaʻi wilderness. Adding an aerial approach allows the team to address a larger area and hopefully save more birds.

Dr. Cali Crampton of KFBRP said, “The increased use of Bacillus should provide a stopgap for ʻakeke’e, allowing the species to avoid extinction long enough to benefit from the proposed mosquito birth control tool. Both Bacillus and the IIT birth control use bacteria to suppress mosquitoes. The two tools are separate but work together to address different parts of the mosquito life cycle: the Bacillus bacteria kill mosquito larvae, while different strains of the Wolbachia bacteria used in IIT result in unviable eggs that never hatch into larvae.

While conservation partners are currently focused on helping birds, people should also see benefits from increased efforts to suppress mosquitoes in Kauaʻi’s mauka regions.

The combined use of organic bacteria and other integrated pest management efforts, such as fixing potholes in roads and overturning containers of standing water, should help popular hiking and camping areas in Kōkeʻe and the Alakaʻi to once again become mosquito-free.

About the project

Hawaiʻi’s forest birds are facing an extinction crisis. Avian malaria transmitted by non-native mosquitoes has decimated native forest bird populations. Of Kauaʻi’s 16 native honeycreepers, 10 have gone extinct. Of the remaining birds, the ʻakikiki is predicted to go extinct by 2025 and the ʻakekeʻe by 2034 (Paxton et al. 2022; see EA for full citation).

The Department of Land and Natural Resources (DLNR) and U.S. Fish and Wildlife Service (USFWS) propose using the Incompatible Insect Technique (IIT) to reduce mosquito populations within approximately 59,204 acres of forest reserves, state parks, and private lands in the Kōkeʻe and Alakaʻi areas of Kauaʻi. This project is intended to suppress mosquitoes known to transmit diseases to native forest birds in critical higher-elevation native forest habitat.

The USFWS and DLNR are preparing a joint environmental assessment (EA) to address the impacts of the release of male mosquitoes with incompatible Wolbachia in the Kōkeʻe and Alakaʻi Wilderness areas. This EA provides background information concerning IIT and outlines the proposed action, potential impacts, and strategies to avoid and minimize potential negative effects of the proposed release of incompatible male mosquitoes within the project area on Kauaʻi. The EA is available below.

Both DLNR and USFWS are members of Birds Not Mosquitoes, a multi-agency partnership urgently working to protect the native Hawaiian honeycreepers from extinction. In addition to the EA below, users may want to review the educational information on this partnership site, including a description of how IIT functions, and answers to Frequently Asked Questions about protecting Hawaiʻi’s birds through mosquito control. Users interested in native birds can explore our native bird profile pages.

KAUA‘I TEAM TRYING TO SAVE NATIVE HONEYCREEPERS PRESSES ON

(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.

EAST MAUI EA APPROVED | Update from March 24 BLNR Meeting

Mahalo nui to the numerous voices that shared their manaʻo with the Board of Land and Natural Resources (BLNR) last Friday, March 24th. Your dedication in championing this vital cause shows the power of collective action and the impact we can make when we work together towards a common goal.

We would like to extend our gratitude to the Board of Land and Natural Resources for their decision to approve the East Maui environmental assessment and authorize the Chair to issue a Finding of No Significant Impact.

The decision to approve the final environmental assessment demonstrates the Board’s dedication to ensuring that large-scale management actions are done responsibly and with consideration for the environmental impact. In addition, their willingness to engage with the public and listen to all perspectives reflects the Board’s commitment to transparency and accountability. The public outreach, scoping meetings, and comment periods allowed for broad community input and a more robust result.

This decision will benefit the manu nahele, particularly the manu of Maui, and the larger ecosystems as we work together to preserve the biocultural treasures of Hawaiʻi.
We will keep you in the loop about the Kaua’i Environmental Assessment coming up next.
