To get a grip on the biodiversity crisis, we'll need to understand how wildlife is threatened in our own backyard.
In healthy populations, the song of regent honeyeaters is complex and long. But where the population is very small, the song is sadly diminished.
By only focusing on preserving the genetic purity of a species, conservationists risk the extinction of isolated populations.
