Hi Madeline
As you rightly suggest, ringing data provides us with the most accurate movements of individual birds, especially the constant effort projects. Unfortunately, there's no way of telling for certainty, without ringing, specific movements of individual birds. The BTO is probably your first point of call given the second Atlas tetrad surveys that have been done since 2007, along with roving records, breeding bird surveys. The current Atlas is being compiled from nationwide winter and spring/breeding surveys so is probably the best source of info for you as far as relatively recent changes to bird movements vis a vis climate change etc. You can access most of the results online at the BTO website from the main page.

There can be some minor differences between some species wintering cf. to our breeding individuals. Continental Robins for example, tend to be a lot shyer than our resident Robins and also tend to have a more orangey/extensive breast colour. Migrant (Russian?) winter Starlings for example tend to develop their breeding plumage earlier than our resident ones prior to migration in late Feb/early March.
