BAIKAL OR JAPANESE TEAL. 
(Nettion formosum. Querquedula formosa.) 
This is a very beautiful bird, which is found in North- 
eastern Asia, penetrating into China and Japan. It takes its 
name from the great inland lake Baikal in Siberia, where it is 
stated by Dr. Jerdon, quoting Pallas, to breed in May and June, 
laying its eggs in a slight hollow on the bare earth, lined with 
feathers. This Teal was among the earliest acquisitions of the 
Zoological Society, breeding from 1840 to 1843, after which 
time the species died out, and was not re-acquired until 1867, 
when two pairs were purchased out of a merchant vessel.
