Area of Study: Regency honeyeater

Darwin Leader Jeongwoo Park brings a unique perspective as an ethologist to the story of the critically endangered Regent Honeyeater—one of Australia’s rarest birds, now numbering fewer than 400 in the wild. In this insightful conservation film, Jeongwoo explores not just the ecological threats to the species, such as habitat loss and invasive species, but also the striking cultural collapse unfolding within its population: the loss of its song. With so few adult males left in the wild to pass on their vocal traditions, young birds are failing to learn proper song—a vital trait for attracting mates. This breakdown of cultural transmission, described by scientists as a “meme bottleneck,” mirrors the concept of genetic drift: a loss of diversity not in DNA, but in learned behaviors essential for survival. Filmed in collaboration with Taronga Zoo, the project documents pioneering work such as “song tutoring,” where young birds are taught wild songs using audio playback and live adult tutors. This behavioral rewilding is complemented by careful genetic management and habitat restoration. Jeongwoo’s film offers a deep, multidimensional insight into conservation—showing that saving a species is not just about numbers, but about preserving identity, culture, and ecological connection.
