The North American Ring-necked Duck Aythya collaris was seen by Abdelhak Elbanalk and Rachid El Khamlichi while birding at the wetlands adjacent to the town of Kénitra (northern Morocco) on 16 may 2011.
While watching three individuals of Ferruginous Duck Aythya nyroca taking off, and a Marbled Duck Marmaronetta angustirostris landing in the same spot, Abdelhak saw a drake Ring-necked Duck and immediately called Rachid to “shot” the bird with his camera. They kept watching the ducks and saw a female Ferruginous Duck coming out from the vegetation. Then they saw the Ring-necked Duck went to the Ferruginous Duck and stayed close to her and after 10 min they both disappeared in the vegetation. "So, this is what we saw. We don’t claim that there where any displaying, but the closeness of the two ducks and the constant effort of the drake Ring-necked Duck to follow and to stay with the female Ferruginous Duck makes us wonder whether it was willing to mate with her", said Abdelhak. This is probable especially that we know that both species are closely related and there are many cases of hybrids with different ducks of the genus Aythya. Have you seen a case like this, if yes we would like to hear from you? Are there any hybrids resulted from these two species, at least in wildfowl collection?
