The Dawn Chorus

Come and learn about the functions and evolution of the dawn chorus, and how human activity is changing it.Listening back, i think it's important to note that this research applies to diurnal (awake in the daytime) birds. Nocturnal birds never came up in my research, probably for that very reason, but I thought i'd mention it here nonetheless!Also, I'm not sure why the last birdsong transition sounds a bit funky - it occurred during the final mastering step, and the rest were fine, so I don't know! Oh well, there's beauty in imperfection! This episode is dedicated to my Aunty Christine.Follow me on instagram: matt.rossellaSupport the show on patreon: patreon.com/blurbs439References:De Framond, L., & Brumm, H.
