Any easy way to get started on your own version of this without needing a mic would be to pull birds seen nearby using the eBird API and pairing scientific names. Won't be as accurate as a backyard mic, but will give you a direction to start.

Also if you have old e-ink device laying around, you can likely setup BYOD with TRMNL (or just buy one https://trmnl.com/) and send the bird images as a private plugin

The e-ink screens linked by OP are much more interesting from a color reproduction standpoint. TRMNL devices are either grayscale or 2 colors.

Very cool I also have a device, but don’t use strava much. Maybe I will now that I can see my results on screen

It really is the small things, fun being able to use hacky superpowers like this. makes me want to call my mom :)
