On this episode we speak with Oliver Metcalf, lead author of a new study using bioacoustics and machine learning (artificial intelligence or "AI") to study a very rare bird in New Zealand. We play some recordings of the beautiful hihi bird that illustrate the success of a last ditch reintroduction effort for this species (and in a place) that are otherwise very difficult to monitor. The findings suggest that bioacoustics can play a key role in assessing the effectiveness of conservation efforts.
