Last night's Owl Prowl was a huge success. I didn't think it was going to work, playing owl calls through bluetooth speakers, but it totally did, very quickly. Amazing to see 3 or 4 Barred owls swooping from tree to tree silently then perching and calling back to the speakers, just like the guide hoped they would. Huge birds flying silently then vocalizing loudly and repeatedly. Magical.
Octodon is a nice general purpose instance.
