Juvenile European Starlings have lost their smooth, mouse grey/pale brown colouring which they have displayed between May and August and are taking on their juvenile moulting look (above left photo) which starts the darker, speckled look they show in the July to September period. They then move on to the adulting breeding look (above right photo) between December and August. There are two other plumages: one being the juvenile (May to August) and the adult non-breeding (September to February). All of these phases have overlapping time periods with all other Starlings depending on the actual egg-laying and hatches dates.
