Your mockingbird shots are really outstanding. I like all of them, but I believe the third is my favorite. The expression and feather detail make it jump out. The mockingbird is also Arkansas' state bird, and they can generally be found in large numbers. They don't tend to visit my yard, but I can drive less than a mile to find them.
My first white-throated sparrows of the season made their appearance yesterday along with a flock of dark-eyed juncos, so I guess winter is truly on the way.
