[QUOTE="JANJ, post: 1408038, member: 20722"] While pale tips to medaian and greater coverts are good features of Caspian - the lack of such is not uncommon in certain sircumstances, such as when worn. The eye shadow, which is not so apparent, and a narrow dark line behind the eye is acceptable, as are the eye size. Head shape not always reliable due to mod- stance and so on. Inner primary pattern is also variable, usually the 'venetian blind' effect is quite apparent in CG, YLG usually with a less pale inners, but also variable but these thing are often difficult to judge correctly in images. Bill colour is good for CG at this age, in fact more in line with it, YLG often less pale bill base. But, as said before - the possibility of it being a YLG is possible.
