Mallard Duck
  Anas platyrnchos.
  
  Mallard ducks are the most familiar of all ducks. They are the ancestor of the 
  domestic duck.
  
  Physical Description
  The male is called a Drake. Its body is black, grey and white. The Mallard's 
  rump is black and the tail feathers are white. It has grey, white and black 
  wings, and has bars of green on them.
  The female ducks are called hens. The females have light darker brown 
  patches on some feathers.
  The drakes moult and take on the same coloration as the hens.
  The Mallard duck chicks are white.
  Mallards are about 50 - 60cm in length and have a wing span of 81 - 95cm.
Habitat
  Mallard ducks are very common over Europe. They are also found in parts 
  of Asia, Africa and America. Mallards that live in the North and East migrate 
  in winter.
  They inhabit parks, canals, rivers, ponds, lakes woodland and gardens. Mallard 
  ducks build their nests on land and line them with feathers.
  
Mallard ducks which are 
  found in parks and villages are semi-domesticated, partly due to the fact that 
  visitors to parks like to feed the ducks bread. 
   
 
  
Call
  Mallard ducks make the familiar 'quack' noise. The drake's call is louder 
  and higher pitched than the females.
  
Nesting
   Laying eggs in March, they lay 9-13 eggs. They hatch in 27 days.
  
Look-alikes: Shell 
  Duck, Ruddy Duck.
  
Diet: They eat small 
  plants and animals. Mallard ducks feed in the water with their heads submerged 
  and their tails sticking up in the air. This is called 'dabbling'. They feed 
  both day and night.
  
Lifespan
  They live about 20 years in captivity.
  
  Mallards have a record of being the most abundant duck in the world.
