SLENDER TEAL, MULLER’S DUCK, OR SUMATRA TEAL. 
(Nettium gibberifrons. Querquedula gtbberifrons ). 
Now classed by the Zoological Society of London as a 
Teal, this slim and agile bird is easily recognisable by the 
narrowness of its build. 
It is an inhabitant of Sumatra, Australia, and New 
Zealand, and the Zoological Society received eighteen Slender 
Ducks in 1860, which have since bred in the Gardens, where 
it is known as Miiller’s Duck. The market value is about £3 
to £4 the pair. The British Museum possesses some well- 
preserved specimens.

giving a spotted appearance; bill black: legs brownish-black ; 
speckled head ; no white ring round eye; wing-bar white.
