Two terrific owl photos

My friend and old Missouri canoeing partner, Bob Cole, emailed me these two, terrific, Great Gray Owl pictures. I have no details about when and where they were taken, and even more importantly, who took them, but will add any info as I receive it. The first picture is a great shot in itself, but the second picture is really special in that it wonderfully illustrates the camoflaging capabilities of this biggest (up to 33"/83 cm.) of all our owls. Several species of owls sit on tree branches, close to the tree's trunk, to achieve this near-invisibility. Does it work? You tell me. Great Grays are rare visitors to southern Ontario in winter, but are fairly approachable and when you do see one, it will stick in your memory for a long, long time.
