The Kauaʻi thrush, also known as the Kauaʻi ʻōʻō, is a small bird native to the Hawaiian island of Kauaʻi. It is known for its distinctive brown plumage and melodic song. This species primarily inhabits forested areas, where it forages for insects and fruits. Once abundant, the Kauaʻi thrush has faced significant population declines due to habitat loss and the introduction of predators. Conservation efforts are ongoing to protect its remaining habitats and promote recovery. The bird is an important part of the island's ecosystem, contributing to seed dispersal and insect control.
