Ornithologists collected museum specimens of the Kaua'i O'o in the early 1970s, preserving physical evidence of the species before its final disappearance from the wild.

Fewer than 500 Kaua'i O'o individuals likely remained by the 1970s, with the species confined to remote wet forests on the island's north shore during its final decades.
