Hej
Er der en hybridexpert, der gider forklare en hybridnovice, hvorfor det er en hybrid.
hilsen Jørgen

Flankefarven er fin for en Halsbåndstrold, men den har alt for meget top, hvilket viser, at der Troldand i fuglen.
Desuden ville man på en ren Halsbåndstroldand, trods billedets kvalitet, kunne se hvidt ved næbbasis.

Tak til THH for oplysningerne. Det var også det jeg regnede med var årsagen. Det er godt med disse kommentarer til hybridænderne.
