Challenging a 50-year-old narrative about Hawaiʻi's native birds, a new study from the University of Hawaiʻi at Mānoa found no scientific evidence that Indigenous People hunted waterbird species to extinction. Published in the journal Ecosphere, the research debunks this long-held myth and offers a new, integrated theory to explain the disappearances.

Researchers found no evidence that Indigenous People over-hunted birds to extinction. Instead, the authors suggest a new theory: the birds died out because of a combination of climate change, invasive species and changes in how the land was used-most of which happened either prior to Polynesian arrival, or after the suppression of Indigenous stewardship. The study also noted that now-endangered waterbirds were probably most abundant just before Europeans arrived, when wetland management was a core aspect of Kānaka ʻŌiwi (Native Hawaiian) society.

Refuting conservation theories

"So much of science is biased by the notion that humans are inevitable agents of ecocide, and we destroy nature wherever we go. This idea has shaped the dominant narrative in conservation, which automatically places the blame for extinctions on the first people-the Indigenous People-of a place. Even where there is zero scientific evidence to support it, the myth of Hawaiians hunting birds to extinctions took root in Hawaiʻi and for decades has been taught as if it was a scientific fact," said Kawika Winter, associate professor at Hawaiʻi Institute of Marine Biology (HIMB) and co-author of the paper. "Our study not only dispels this myth, but also contributes to a growing body of evidence that Indigenous stewardship represents the best ways for native birds to thrive in a world where humans are not going away."

This study re-examines existing evidence without the bias that the discipline has increasingly been criticized for-the idea that people are separate from and inherently bad for nature. The research provides a more nuanced understanding of history, paving the way for an increasingly robust approach to conservation research.

"Science has matured to a point where graduate students are being trained to challenge its own long-standing world view," said Kristen Harmon, lead author on the paper who recently earned a PhD from the College of Tropical Agriculture and Human Resilience (CTAHR) Department of Natural Resources and Environmental Management. "Our interpretation of historical ecology, how ecological systems change over time, influences our approaches to solving global-scale ecological problems. Bringing together information from different disciplines and knowledge systems can yield a more accurate picture of reality, which is ultimately the goal of every scientist."

Empowering Indigenous stewardship

The study's conclusions are expected to help transform conservation actions in Hawaiʻi, particularly for the recovery of endangered waterbird populations, such as ʻalae ʻula (Gallinula chloropus) and ʻaeʻo (Himantopus mexicanus knudseni).

"Recent studies support what Hawaiians have always known-that restoration of loʻi (wetland agro-ecosystems) is critically important to bring these waterbirds into abundance again," said Melissa Price, an Associate Professor who runs the Wildlife Ecology Lab at CTAHR. "If we wish to transform our islands from the 'Extinction Capital of the World' into the 'Recovery Capital of the World' we need to restore relationships between nature and communities."

This new understanding could help change how we protect these birds and mend long-standing disagreements in the community.

Ulalia Woodside Lee, who was not a part of this research project, offered some reflections as the Hawai'i and Palmyra Executive Director for The Nature Conservancy, "For generations, Native Hawaiians have been criticized for causing the extinctions of our precious native birds. This has contributed to a breakdown in trust between the Hawaiian community and conservationists, and the exclusion of Native Hawaiians from important conservation decisions. This study will help us to move past those untruths, so that we can all move together into a brighter future where our native species are thriving again."

"What we found is that none of these previous explanations hold up, including the dominant one that claims that Native Hawaiians hunted birds to extinction."

"And so what our theory suggests is that it was a confluence of changes with climate, introduced species, shifts in the forest and other things that have really contributed to the extinction of these birds."
