I worked at home today so at lunchtime I shot over to North Duffield Carrs where I was greeted by two Bewick's Swans in amongst the flock of Mute and Whooper Swans. Interestingly these were the same two birds I found back in mid-December - I can tell this because one of them was Darvic-ringed. Today I saw Craig, the Natural England Warden who'd actually been able to read the code.
Turns out it was ringed in November 2007 in The Netherlands (Darvic ring number yellow on left leg 702). This bird was then seen at Slimbridge WWT in 2007 and 2008 and was then seen at North Duffield in January 2009, December 2009, and February 2010 but was not reported from either here, or Slimbridge in the winter of 2010/2011 or 2011/2012.
This really shows the value of darvic-ringing/colour-ringing! I only got a 'record-shot' of the birds today, and have included a couple of pictures from last time I saw the birds.

Also present here was an increased flock of Pochard - at least 62 birds now! Also an increase in Tufted Duck (c.25) and Pintail (c.8-10).
Yesterday I got three year-ticks in the dark! Little Owl, Redwing and Snipe!
