$2 WATER FOWL OF INDIA AND ASIA. 
The Pink-head by its dark body, buff quills, and pink 
or pale drab head. 
The Marbled Teal by its pale, washed-out-looking plu- 
mage, and silver-grey edgings to the pinion-quills. 
Of the genera of peculiar form the sexes are very un- 
like, but the following structural characters distinguish 
them from all other Indian Ducks of this section. 
The Pintail has a long sharp tail, half as long as the 
wing or longer. 
The Shoveller has a huge mis-shapen bill, very long, 
and twice as broad at the tip as at the root. 
Then come a number of species, referred to several 
genera, of which the male and female often present 
hardly any point of colour in common. They may, 
however, be sorted out partly by size and partly by the 
colour of the wing-bar. 
Of the bigger Ducks, with the wing nine inches or 
over :— 
The Mallard and its alles (three species) have a steel- 
blue or green wing-bar, edged with white. 
The Gadwall has a white wing-bar and the fringing 
of the bill showing well below the upper chap. 
The Bronze-cap has a black or green-black wing-bar 
and grey feet. 
Of the smaller Ducks, or Teal, with the wing under 
eight and-a-half inches :— 
The Garganey has the fringing of the bill just showing 
below the upper chap and the wing-bar dull green or 
wanting. 
The ordinary Teals (three species) do not show the 
fringing of the bill when this is closed, and have the wing- 
bar black and brilhant green or bronze.
