Be in nature this week without having to leave home — perfect for those of us in lockdown. First up, our brand new podcast, Nature Track. No music, no voices, just the beautiful sounds of the Australian wilderness in long, uninterrupted recordings — the perfect relaxing soundtrack for work, exercise, meditation or sleep. Secondly, our new citizen science project, Hoot Detective. Listen to audio from the wild across Australia and see if you can identify the owl calls — it's very exciting when you hear your first boobook! We also look at the emerging field of ecoacoustics; the cost of ferals in Australia; and the missing spider wasp. And if you missed Catalyst you can catch up with the Wildlife Revolution.
