I had started working through the dabbling ducks (see below), following the order given in the IOC World Bird List. Now with the unified AviList available, it makes sense to follow that sequence, but this has resulted in a whole lot of shifts among the ducks. I will now work through some of the gaps that have opened up before continuing with the dabbling ducks. Below are those species I had covered already plus one or two hybrids added on an ad hoc basis.
Knob-billed Duck Sarkidiornis melanotos
Maned Duck Chenonetta jubata
Blue-winged Goose Cyanochen cyanoptera
Diving ducks (Family Anatidae: Subfamily Aythyinae)
Dabbling ducks (Family Anatidae: Subfamily Anatinae)
Hybrids: Sea duck (Family Anatidae: Subfamily Merginae) x Dabbling duck (Family Anatidae: Subfamily Aythyinae)
