Mallard or Wild Duck
Anas platyrhynchos
Well truly the ubiquitous duck, certainly in the Northern Hemisphere. Where it didn't get to by its own efforts, it has been introduced, including into chunks of Oz and NZ. It has often seemed to me that within a few minutes of flying anywhere in the world you hear that irritating 'quack-quack-quack' of a Mallard. I'm sorry, I live by a pond and being woken by that loud 'quack-bloody-quack' at 3am gets stale quick, and they come round for bread, and bang on the back door, so I kinda have a love-hate relationship with this species. The chicks are cute though!
As 'the' duck it has had a fair number of names: Stock Duck (Orkney), Mire Duck (Forfar), Moss Duck (Renfrew, Aberdeen), Muir Duck (Stirling), Grey Duck (Lancashire) and the They've Shit on the Back Step Again Duck (Here).
Like so many birds they can forecast the weather, as in:
  " When ducks are driving through the burn
  That night the weather takes a turn."
In early usage the male was called Mallard and the female just Duck, the young were delightfully called 'Flappers'. We've all heard of the game 'ducks and drakes' for skimming stones on water which comes from the half-run on water half-fly actions of disturbed ducks.
Pointer in the "Oxoniensis Academia " (1749) relates the custom of the All Saints College, Oxon, of holding a 'Mallard Night' on 14th Jan every year to celebrate/remember a drake mallard imprisoned in a gutter or drain under the All Souls college and grown to a "vast bigness". I give you therefore parts of "The Merry Old Song of the All Souls' Mallard".
  " Griffin, bustard, turkey, capon,
  Let other hungry mortals gape on;
  And on their bones their stomach fall hard,
  But let All Souls' men have their Mallard.
  Oh ! by the blood of King Edward,
  Oh ! by the blood of King Edward,
  It was a swapping, swapping Mallard.
  The Romans once admired a gander
  More than they did their chief commander
  Because he saved, if some don't fool us,
  The place that's called the head of Tolus,
  Oh ! by the blood, etc. "
It goes on but you probably have to be well bleutered to really want more. I'll move on.
