Duck ID Check - Grangettes on Lake Geneva, Switzerland. (1 Viewer)

Hello,
Sorting though some photos from 2021 I remembered this picture of a duck seen at Les Grangettes on Lake Geneva in May 2021. I thought it was a male Pochard but was never 100% sure. Can anyone advise please.
Best regards and thanks in advance

Hello,
welcome to birdforum.
No, the choice is between a Tufted Duck and Greater Scaup. Uniform dark (nearly blackish) head and upperparts, contrasting with quite uniformwhie belly is bad for Pochard. They have either a red-brown head in male types and greyer body or a complexer head pattern in female types (hiope rthat helps).

Its a Tufted Duck by:
  • just discernable tuft at rear head
  • many (at least) female Greater Scaups have a more extensive white blaze around the bill in may.
  • head seems not bulky=rounded enough for a typical Greater Scaup

Many thanks for the help and quick reply. It just looked brown to me compared to the obvious Tufted duck that were also there - so thanks for the ID.

I think it's probably tufted on balance although I find it difficult. I'm pretty sure the "tuft" is actually part of the wall behind. One fat tuftie!

Hard to judge for sure but my suspicion would be Tufted. Still though with the prevalence of hybrid Aythya in Europe, I frequently avoid trying to be too certain. In a year of keeping my eyes peeled for Ferruginous Duck or anything else here in CH, all of my interesting birds have been either the common species or likely hybrids :ROFLMAO:
