I was just Googling myself again to see what turned up (which is mostly just stuff having to do with Lovecraftian fiction), and was reminded of this old website that is still there:  Owl Sounds.

The main feature of the page are zipped wavs and mp3s of barred owls singing outside my house.

This web page must be at least ten years old now.  When I first put it up I hadn't even heard of the mp3 format, which is why I originally used zipped wavs.  Later on (six years ago), I converted the old wavs to mp3 because they're easier to download on dialup.

Back when this page was newer, it got loads of traffic.  I got several emails from different school teachers who all told me they were using the sounds in their classes, which was pretty cool.

Oh and, uh, I kind of have a thing for owls.
