The northern shoveler, or really, to keep it simple, referred to as the shoveler. Sounds a bit like a hit TV series where a tough guy enforces the digging of holes. These were shot early morning, hence the lovely light.
These are surface feeing ducks with huge spatulate bills.
These were shot last year.
I have heard that they are OK to eat, but not particularly tasty. But do not try this in HK where all birds are protected. By law.
Here some simple shots of them flying....
and a couple of them splashing and feeding
