What animals have gone extinct in Hawaiʻi?

Answered by Randy McIntyre

Several animal species have sadly gone extinct in Hawaiʻi, some of which include birds such as the Kauai akialoa, Kauai nukupuu, Kauai oo, large Kauai thrush, and Maui akepa. These extinctions serve as a tragic reminder of the fragility of our ecosystems and the impact of human activities on wildlife.

The Kauai akialoa, a bird endemic to the island of Kauai, was last confirmed to be seen in 1969. Its decline was attributed to habitat loss due to deforestation and the introduction of invasive species, which outcompeted the akialoa for resources.

Another bird species, the Kauai nukupuu, was last sighted in 1899. Its extinction is also linked to habitat destruction, as well as the spread of diseases by introduced mosquitoes. The loss of native forests and the introduction of non-native bird species contributed to the decline of the Kauai nukupuu population.

The Kauai oo, a striking black and yellow bird, was last confirmed to be seen in 1987. Similar to the previous species, its decline was mainly caused by habitat loss and the invasion of non-native predators, such as rats and feral cats. These predators preyed upon the eggs and nestlings of the Kauai oo, leading to their eventual extinction.

The large Kauai thrush, also known as the Kamao, was last confirmed to be seen in 1987. Its extinction can be attributed to a combination of factors, including habitat loss, predation by invasive species, and the introduction of diseases. The loss of native forests and the spread of non-native predators contributed to the decline of this bird species.

The Maui akepa, a small yellow bird native to the island of Maui, was last confirmed to be seen in 1988. Its extinction is mainly attributed to habitat destruction caused by deforestation and the introduction of non-native plant species. The loss of suitable habitat and the lack of food resources led to the decline of the Maui akepa population.

These extinctions highlight the ongoing challenges faced by Hawaiʻi’s unique and vulnerable wildlife. The introduction of invasive species, habitat destruction, and the spread of diseases have had detrimental effects on native species. Efforts are being made to protect and restore habitats, control invasive species, and raise awareness about the importance of conservation.

As an expert in the field, I have witnessed firsthand the devastating impacts of human activities on wildlife in Hawaiʻi. It is disheartening to see the loss of these unique and beautiful species, and it serves as a reminder of the urgent need for conservation efforts. Through education, research, and collaboration, we can work towards preventing further extinctions and restoring balance to Hawaiʻi’s ecosystems.
