Thanks to everyone who gave me ideas on the identity of the dusk screecher on P5.. and my yard. I haven't heard it again, but I've been listening to audio-file after audio-file and still nothing matches it. The only ones who come close to matching the frequency/pitch and sound clarity would be a loud Screech-Owl whinny IF it had NO tremulousness at all, and rose then fell in a second or two, and then be silent. The Sasquatch site has 2 recordings of what they identify as N. Saw-Whet owl, and those recordings have a very similar pitch and clarity, (not sure those are correct sound terms) but that's the only site I've ever found of a Saw-Whet owl making any noise but tooting or some kind of squeaky noise. I just read that Saw-Whet Owls like to nest in hollowed out pileated woodpecker holes, and there sure are a lot of those out on P5, but I guess it is too early for them to be thinking about nesting.. but maybe establishing territories? I've listened to a lot of Barred Owl recordings (everything on the Macaulay library site) but most, if not all of them I could recognize or could easily imagine coming out of a Barred Owl's beak. There really was no hoot-like, toot-like, raspy or tremulous quality to the sound. I think it was a noise a(n evil) person COULD have easily have made. I've got to get used to carrying my iphone with me during the evening with my finger poised on the RECORD button! I'm not sure if it ever repeats the noise, though, so I have to be vigilant and have quick reflexes! (Something tells me I'm not going to get a recording : ( ) Maybe someone else in the Norwich area will hear it and be better at describing it than I am. I will try to get up the nerve to go out there again around the same time of afternoon. Has anyone ever heard a dear actually scream? Not snort, but scream like a woman? I've never heard it but there are people who insist that they have heard it.
