Rather handsome duck, green and purple iridescent plumage. This is the only duck like this on our local pond and has been there for over 2 years now. Is it an escapee? Can anyone help identify it please.

Cayuga Duck

This is a Mallard, and it is probably correct to describe it as a 'Melanistic Feral Mallard'.
Although it may not be a pure bred example it looks like a drake Cayuga Duck, which is a large domestic breed of Mallard with this colour plumage;
The Black East Indian is another breed of Mallards that is similar in colour but these are much smaller;

If you just call odd looking ducks like this 'domestic Mallards' you'll usually be right!

Odd - looking mallards seem to be flavour of the month - this is, as you noted, a particularly handsome specimen!
