The Dunnock (Prunella modularis)
There is something about a Dunnock in Winter that makes it more attractive to view. Although there is a slight variation in colour in the two images here, that is down to the light at the time. However the markings appear to me to stand out more at this time. Perhaps its because of the surroundings (the dull brown of dead foliage) make it stand out. In Spring and Summer there is so much more colour in the background.
