to assume that it is migratory. In the present case, in the absence of any direct 
statements to this effect, the dates, which have been recorded by various authors, 
tend to show that, while the species breeds in China (Swinhoe), it descends in 
the cold season with the N. E. monsoon into the Malay Peninsula and the East 
Indian Archipelago and stays till the S. W. monsoon begins, — that is to say 
from September-October to March. We make this statement with spme hesi- 
tation, inasmuch as it is certain that some specimens remain behind (though 
perhaps not south of the equator), a specimen in the Leyden Museum having 
been obtained in Morty Island by Bernstein on August P\ 1861. 
On the other hand, all the dates but one, which we have been able 
to find, point to its being a migratory species. Davison and Bingham speak 
of it as a rare straggler in Tenasserim, and a specimen given to Swinhoe by 
Captain Ebert flew on board ship off the Pescadores early in May, facts which 
also point to migration.
