A couple of days ago I found two Shelduck at North Duffield with darvic-rings. Thanks to an update from Craig at NE LDV I got the details of them:
Bird 1: ZL - was ringed on 6th February 2012 at Wheldrake and not seen/caught again until my sighting.
Bird 2: CF - was ringed on 2nd June 2010 at Wheldrake, was present in the LDV last March was was re-caught at Thorganby on 25th March 2013.
I also had another darvic-ringed bird on that date, and at least two today that I couldn't read due to their legs covered in mud!
If you're in the area (or further afield) keep an eye open for darvic-ringed/colour-ringed birds as there's a lot of them about! A total of 52 Shelduck were caught in the LDV this year, with 100 caught last year too...
