Very pretty bird and very beautiful photographs. The pictures have it all - sharpness, perfect exposure, creamy OOF backgrounds, and great compositions. Hard to pick a favorite, maybe #3.
I love that bright warm orange against that cold snowy background. I saw a couple of these recently in the Sinkyone Wilderness on the north coast of California. Though I have a pretty good grasp of our common local birds, the Varied Thrush was a new one for me! Lovely little bird... :-)
