compared. Worn specimens show a much more oily green 
tint on the mantle and inner secondaries. 
Common along the coasts of the NW. Malay Penin- 
sula and on the islands of the Straits of Malacca during the 
winter months, but rare even on migration in the south of the 
peninsula. Apparently not resident.

In the Malay Peninsula this species has been found breed- 
ing in July but as a resident it is scarce. It is, however, 
common on migration during the winter mcnths.

A fine adult female from Ko Khau, Trang, has the wing 
(measured dry) 232 and an immature male from the same 
locality 237. Shelley loc. cit. gives the wing of an adult as 8} 
in. (210) so that the specimen he measured, if correctly recorded, 
must have been exceptionally small. Gyldenstolpe’s adult male 
from Koon Tan, North Siam, measured 237 mm. 
The species is evidently fairly common in the northern 
third of the Peninsula though probably only in the winter 
months but is extremely rare south of the latitude of Penang. 
As is the case with so many migratory species birds that have 
not yet attained the fully adult plumage appears to be in the 
great majority.
