Could someone confirm the age of this sinensis Cormorant please? I aged it in the field as 1st summer, but would like others' opinions. The bird was present at Thornwick Pool, Flamborough, on 24th & 25th June, but I found it dead today. The primaries (especially outer ones), secondaries and rectrices look very worn, and surely the crown, hind-neck & upperparts would be browner if it were a juvenile. The humerals and their largest coverts (I was surprised how small these feathers are) appear new; second generation?
Thanks in advance.
