Redwings return

My first Redwings of the autumn on Flash Lane this morning, at least twenty birds with around 50 Mistle Thrush. Ken had also seen Fieldfare.
The Redwing looked dark, are these Turdus iliacus coburni from Iceland rather than nominate iliacus from Scandanavia and Russia? Looking in Martin Garner's Challenge Series Winter they certainly show the heavy breast streaking and darker crown and ear coverts. Interestingly, there have still been very few Redwing on the east coast so have these birds come from the NW?
I've provided a more detailed write-up on the Redwing on my Wildlife Diaries site and included additional photos of Icelandic and nominate Redwings for comparison.
