Not a load of bull

For anybody who is interested in maybe trying to age birds in the field in simplified terms, i will post various points on the blog (if only just for you Dougie). Bullfinch are not exactly the easiest to start with but subtle differences can be seen. Apart from 4 old greater coverts the juv(5) male has retained the brown fringed carpal covert.

Whereas the bird below has moulted the old carpal covert and replaced it with the grey fringed carpal covert making this bird an adult(6).
