Being an old-timer I do remember this sequence of events. I recall walking over to the Multnomah County Library in downtown Portland to see a barred owl perched High overhead. This had been reported on the old phone tree of long ago, before the internet.
But I do have a question, do Barred owls eat red tree voles?
