My mom, just now, heard an owl at the WFA house hooting away (around 11 PM). For years I have listened for them at night here and haven't heard any, so this is absolutely exciting. I've been crossing my fingers that this autumn and winter are great for owls - I've loved the snowy owl irruptions, spotting them around this area every couple of winters.
My mom does not know her owl calls, but she made the call for me, and it's almost certainly that of a great-horned owl. The habitat at the WFA house is perfect for them. I'll have to keep my ears open!
