More pics from Vadu. I'm not sure about the first one (pics 1 and 2), but i would go with YL. 3 is a nice Caspian portrait. 4 and 5 are with de same individual (a 1cy YL).
hi cristian,
male 1cy caspian in #997! with that big bill, very pointed tip, strong collar, pale distal parts to MC and GC and thumbnail-like broad tertial crescents as well as general appearance (jizz) there can't be any doubt.
all birds (except the BHG) in #998 are YLGs.
that juv/1cy caspian is a good catch! we haven't got many pics of juv caspians.
cheers
