Crates, Ross; Langmore, Naomi; Ranjard, Louis; Stojanovic, Dejan; Rayner, Laura; Ingwersen, Dean; Heinsohn, Robert


Cultures in humans and other species are maintained through interactions among conspecifics. Declines in population density could be exacerbated by culture loss, thereby linking culture to conservation. We combined historical recordings, citizen science and breeding data to assess the impact of severe population decline on song culture, song complexity and individual fitness in critically endangered regent honeyeaters (Anthochaera phrygia). Song production in the remaining wild males varied...[Show more]
