Hi everybody
I saw a strange duck in the PN of Aiguamolls dell Emporda, Spain. I suppose it is a kind of Shelduck because of its size, easily comparable to other Common Shelducks swimming around, and wing pattern : white under and upper wing coverts. After a look in HBW vol1, it looks like a female Australian Shelduck (!) because of white eye-ring, base of bill, and collar. But many differences remain : brown color of head, difference of color between belly and upper body, white line betwen undertail and belly, and rusty undertail. That is the reason why I am suspecting an hybrid between Australian Shelduck and an other Shelduck, maybe common or ruddy. Can anyone help me to "choose the right hybrid"? Is an hybridation possible between a Shelduck and other ducks?
Thanks a lot
