I was quite impressed by the large differences between the Komorners I have seen on German shows. But the breed has under-gone great changes here in Germany and other European countries because of standard desires and therefore strict selection towards a certain aim. The desire of European KT breeders leans towards full, round heads, the beak blending into this gentle arc. The eye is rather large for this head surrounded by an intense red colored cere. The Magpies always have bull eyes, the other varieties must have eyes of pearl color.
American KTs are longer in the beak and also the head , which is of elongated round shape.
A true name, because feeders are used in most European KTs. It seems to me like the crest complex of the American KT goes near the ornaments of the Old Dutch Capuchine, even if this comparison might be a bit extreme. The German standard drawing is more realistic in this point. When comparing the US standard drawing to birds I have seen on photographs, the birds on the photos all look rather long in the back part of the body, all not sloping down that steeply as shown on the desired ideal. The birds I have seen on photographs seem to me like they still lean towards the type of bird shown in Levi's book, even if there are differences.
