Great Grey Owl Sighting

Just before Christmas I was outside working on adjusting the Christmas lights and two houses down the street I could hear some squeaking. After listening for a minuter or two I realized this was our neighbour playing with their dog. A little squeak here and there...it was pretty funny. This was around dusk. Suddenly I saw what turned out to be a great grey owl just coasting over my head, through our neighbour's yard and landing on the tree to observe. It was amazing to see the wing span and how smooth it flew. This is actually the third owl sighting in the last 3 years.
