I'd ringed him last year on the 5th of March as an adult, but he has a greater covert pattern that looks like he was an age 5 (born last year). This makes me more nervous about ageing Robins! I reset the trap and caught him again, but the blackbird who also uses it didnt come close enough.
Robin with 4 OGCs that look juvvy.
On Sunday I went along to Wicken Fen for a spot of ringing and a meeting/practical about nest recording. Nothing special on the ringing front but the nest recording people were phenomenal! They spotted things I swear were invisible.
Since then I've been on brief forays into the orchard, no nests found yet but I have seen some Lottis with nesting material - so they are nesting somewhere nearby.
Hi Limey: after capturing many such Robins ringed in previous years, many of them retained the major outer coverts pale color and shape of tile.
ReplyDeleteMany also with the upper jaw of a fairly uncommon and can not be assured as age, age 4 if I place a Euring to these birds.
If gets 6 Euring only and exclusively to those individuals who have major coverts without pints, after many years capturing birds marked in previous years, I have come to the conclusion that these if they are adults.
Congratulations on your blog. Sincerely Fernando Gavilan.
Talking about it to other ringers they appear to rely more on tail shape, which I'll be bearing in mind for future captures!
