A couple of nights ago I was out on the back deck doing some observing with my large mounted binoculars, looking for a few open clusters and a few Messier galaxies. I'm in a suburban setting with adjacent woods. As happens a couple of times a month when I'm observing deep sky objects for an hour or two before bed, I heard a non-human animal shriek that mimics the "cry of the banshee." Turns out to be a night cry of a barn owl. This was confirmed by my naturalist/gentleman farmer neighbor who raises a few chickens. Apparently, the barn owl doesn't mind living far from his chickens and has been around for a couple of years now. Unless you have heard a barn owl calling out at night, you would think you were dealing with some dangerous predatory quadruped like a Fisher Cat (which we also have around).... but the cry of the barn owl is very distinctive. The only similar sound that I've heard was some years ago when I accidently stepped on my cat's tail. That roughly captures the idea of the sound...
