Rosybill (Rosy-billed Pochard) x Pochard (Common Pochard) Netta peposaca x Aythya ferina
At the time I identified these birds as Rosybills but upon seeing one of the photos of the male Joern pointed out some inconsistencies with that ID. Most obviously is the back colour which seems too pale for a pure Rosybill. There is perhaps also a little too much black on the bill and on the vent. We think the most likely ID is Rosybill x Pochard.
I think the female may also be a hybrid - I'm not well-versed in the extent of variation within pure Rosybill but the bill pattern of this bird looks suspiciously Pochard-like to me.
