Today we managed to photograph the wings of a juvenile, complete with 5 old greater coverts, and an adult in main moult, which illustrate really well some of the ageing features highlighted in the article.

Ageing Dunnocks
As the season progresses and eye colour becomes a less reliable character, I have been referring to an article from Ringing & Migration (Vol 28 (1): June 2013) on ageing Dunnocks, written by Stephen Menzie and Bjorn Malmhagen. I have found it very useful but the copy I made of the illustrations of the wings weren't very clear.
