I've got a raspberry pi that records birdsong at sunrise each morning here for those interested <a href="https://www.mohiohio.com" rel="nofollow noreferrer">https://www.mohiohio.com</a> Although it mostly recorded wind today. Scroll to get to another day. RSS feed available.
if you enjoy this, the Merlin bird app is pretty cool - it will show a waterfall visualization so you can see the pitch changes. it also can identify birds in real time.
I remember seeing a few years ago, maybe it was a landing page for a bird song data set, or classifier, a big grid of tiles of maybe spectrogram thumbnails of bird songs. Does anyone know what that was?
Beautiful. I want to give out a recommendation for the python library librosa which can create similar visualizations (although in a cartesian space as opposed to polar coordinates)
