This is what I first thought it was:
But it turned out to be a Barred Owl.
They are an impressive sight, especially when they are that close!!
Of course, most of us see them in the daytime just sitting in a tree resting up for the upcoming night's hunt.
There are quite a few of them around here and I just love to hear their calls. The have quite a repertoire. The following is a link to a YouTube video that will let you hear their vocalizations:https://www.youtube.com/watch?v=y5zc-NHIipw
I love these birds and love to listen to their calls and conversations. Now, you all have a great day and a great night to night, you hear?
