hi cristian,

the extensivedark mark on bill and small mirrors indeed suggest a younger bird but it's much more likely a 4th cycle (now 5cy) than 3rd cycle - most 3rd winters don't have p9 mirrors and at least show some dark markings to alula and primary coverts.

best,

lou

Thank you for your comment, Lou. 5cy seems to be the most likely age...
