The thumbnail had Alan Murphy all over it already...excellent shot. Technically very good as usual. I love the OOF branches in the lower right as they add a lot of depth to the photograph. Only a different pose could improve this IMO. Very nicely done!
Alan...lovely shot as usual. The sharpness of the cactus makes this image. But I find the bird a little oversharpened....but that might just be my personal taste.
