@jonty I never considered that this would be a thing that exists, but now you've mentioned it I'm like "obviously this exists and works quite well"
@jonty essentially the perfect use-case for classifier models
@gsuberland There's also a bat version! They're a lovely thing to have set up, you get to see when birds arrive on migration.
@jonty does the bat one use an ultrasonic mic?
@gsuberland Yep, but it turns out most decent mems mics will do these days and there are some nice projects that bolt a USB interface to them
