I took this photo a couple of years ago at Frampton Marsh in Lincolnshire. Their body shape suggests mallard but I can't find any reference for their colouration. Can anybody help?
Hi Bill, yes they are one of these domesticated variety of Mallards which seem to be everywhere these days. I think it may be a variety known as Khaki Cambells.
No problem Bill
If you want to see the weird and wonderful varieties they've bred from the humble Mallard take a look HERE.
