Last week we caught another good number of Shelduck in the duck trap, this bird (photo below) is a good example of a 5 (young bird). Notice lots of grey/brown feathers in the white wing panel and large white tips to the primaries/secondaries.
For our first post about ageing Shelduck see: 'Shelducking' 15/02/12, similar posts are available for help with ageing Teal and Wigeon.
