Reed Bunting?

What a difference a day makes!  Today it is bright and sunny although still very cold; we have a steep access drive and this morning it was slick with black ice.  I walked down to the prom and found a lot of birds in the salt marshes.  I think they were mostly Reed Buntings but this one in particular had much brighter and more rufous colouring than I have noticed before.  So if anyone thinks it is something different then please let me know.
