It was a few years ago on Loch Morlich in Scotland where I encountered what I think is a female Spatula querquedula. The species is listed as least concern on the Red List, but numbers are in decline and threats are aplenty:
habitat deterioration and destruction (dam building, irrigation)
These two Anas platyrhynchos had made their home in the little park around lake Kuchajda in the middle of Bratislava. I find mallards beautiful and totally underrated. The species is considered least concern and in some regions invasive.
Tadorna ferruginea is a rather special bird. In Buddhism, it’s sacred. The species is also nocturnal.
I saw this specimen at the Farmoor reservoir near Oxford – that’s really unusual. It’s quite likely the bird has gone feral, because the main area ranges from south-east Europe to Asia. The European population is in decline, mainly because of hunting.
