History Photographed on Instagram: "The Kauaʻi ʻōʻō was the last of the Mohoidae, a bird family that existed for over 15 million years. Once common in Kauai’s forests, it went extinct due to predators, disease, and habitat loss. Its haunting final call, recorded in 1987, was a song for a mate that would never come. Its extinction marked the loss of an entire avian family in modern times."
