A number of Hawaiian honeycreepers are going through imminent extinction resulting from avian malaria carried by invasive Southern Home Mosquitoes. Members of the multi-agency partnership Birds, Not Mosquitoes (BNM) have begun releasing non-biting male Southern Home Mosquitoes on Maui and Kaua‘i that cut back invasive mosquito copy and trigger their populations to lower. Following years of rigorous examine and evaluation, the releases started in November 2023 after regulatory approval from state and federal companies.
“This actually is a essential milestone because it demonstrates the power of our partnerships to make sure the long-term survival of our island’s honeycreepers,” stated Dr. Earl Campbell, U.S. Fish and Wildlife Service Area Supervisor for the Pacific Islands Fish and Wildlife Workplace. “It’s made much more momentous as our collaborative efforts happen throughout Makahiki o Nā Manu Nahele, the 12 months of the Forest Chicken.”
This work is a part of the U.S. Division of Inside’s Technique to Stop the Extinction of Hawaiian Forest Birds and it’s pressing: Hawaiʻi’s forest birds have declined from greater than 50 completely different native honeycreepers to only 17 species remaining as we speak.

“Manu (birds) are revered as our ‘ohana (household) and for too lengthy, their songs have been declining,” stated Ulalia Woodside Lee, Govt Director, The Nature Conservancy Hawai‘i and Palmyra. “We’ve a kuleana, a accountability, to present nā manu nahele (forest birds) an opportunity to nourish Hawaiian tradition and spirit, in addition to pollinate our forests and hold them rising. We’re trying ahead to the day when honeycreepers aren’t uncommon in Hawaiʻi’s forests.”
Mosquitoes are quickly transferring to larger elevations because the local weather adjustments and native forests get hotter and drier. With out considerably decreasing mosquito populations, a number of native chook species are more likely to go extinct within the wild in lower than 10 years, together with the Kiwikiu and ʻĀkohekohe on Maui, and ʻAkikiki and ʻAkekeʻe on Kauaʻi.
“After many years with out the instruments to unravel this drawback, this undertaking is our finest probability to avoid wasting the birds and native forests for future generations,” stated Dr. Chris Farmer, Hawai‘i Program Director for American Chicken Conservancy (ABC). “I’m excited and honored to be a part of this historic collaboration to deal with troublesome, beforehand intractable conservation issues, and decide to long-term options.”
The male Southern Home Mosquitoes, which don’t chunk or transmit illness, carry a pressure of the frequent, naturally occurring Wolbachia micro organism. After they mate with females within the wild, which carry a special pressure of this micro organism, their eggs don’t hatch, inflicting the mosquito inhabitants to lower. No new species are being launched to Hawai‘i; each the mosquitoes and the Wolbachia micro organism are already right here. This technique has been safely used to regulate the unfold of human illnesses by mosquitoes all over the world.
“This undertaking is our greatest alternative to reverse the development of shrinking chook populations for these species which might be discovered solely in Hawaiʻi,” stated Dr. Lindsey Nietmann, Forest Chicken Restoration Coordinator for the Hawai‘i Division of Land and Pure Sources Division of Forestry and Wildlife. “Along with defending the birds that stay in our forests, we hope these efforts will in the future result in the discharge of captive populations which might be at present in conservation breeding services and awaiting re-introduction to the wild.”
Monitoring is an important a part of this undertaking. It helps decide if mosquito populations are reducing, malaria prevalence is reducing, and native chook populations are stabilizing or growing. Maui Forest Chicken Restoration Undertaking (MFBRP) has been main implementation on Maui. Panorama-level deployment has begun over a number of thousand acres of distant forests on East Maui.
“Our monitoring is pushed by science and is designed to assemble the absolute best information,” stated Dr. Christa Seidl, MFBRP’s Mosquito Analysis and Management Coordinator. “Our discipline group offers important boots on the bottom and within the air, spending lengthy, usually moist days in distant forests checking mosquito traps and gathering information.”
Kaua‘i Forest Chicken Restoration Undertaking has been main efforts on Kaua‘i, and has accomplished small-scale pilot releases to evaluate how far the male mosquitoes journey. Subsequent steps embody releases over a number of thousand acres of forest on the Alaka‘i Plateau.
This undertaking couldn’t have occurred with out substantial state and federal partnership and funding. Specifically, the present administration’s Investing in America Agenda dedicated almost $16 million by way of the Division of the Inside to catalyze extinction prevention in Hawai‘i. This funding is a part of the broader Hawaiian Forest Chicken Conservation Keystone initiative. The Nationwide Fish and Wildlife Basis can also be a significant supporter.
“This effort represents the end result of many years of collaborative analysis between the Division of the Inside and State biologists, non-governmental organizations, and personal enterprises,” stated Dr. Dennis LaPointe, Analysis Ecologist at United States Geological Survey Pacific Island Ecosystems Analysis Heart. “The well timed growth of this protected and efficient instrument to suppress mosquito populations in forest chook habitats brings new hope for the preservation of the remaining Hawaiian honeycreepers.”
In 2024, the partnership will proceed releases on Maui, develop releases on Kaua‘i, and put together a Statewide Environmental Evaluation. The State Division of Well being will lead that evaluation, which is able to handle software of this technique for each conservation and public well being.
