This was taken right outside a building called the Menil Collection in Houston. I was surprised at the age of this limb. There are several tree branches that touch the ground in this area and this one branch looked like it was on its way to the ground as well. Thoughtlessly, I touched it and it began to wobble. This bird flew out of nowhere, screeching at me and perched right next to the branch. He was not going to let me mess up his tree! Shame on me. Anyhow, I changed the photo to greyscale before selecting each little strand of moss. I then RGB'd the image again and altered the color in the moss only. Please view full size.
