The Eastern Baya inhabits the Malay Peninsula, Tenasserim and Burma and was 
also obtained in Siam though it was apparently rather rare. 
Like the next species it inhabits grassy plains and rice-fields and is generally seen 
in flocks feeding on seeds. 
The wing measure is a little shorter than that one recorded by Harrert (Novitates 
Zoologice Vol. IX. 1902 p. 578).

do Chieng Hai 1/s 1914. L = 130 mm.; W = 65 mm.; T = 45 mm.; C = 14,5 mm. — Irides: black. 
Bill: black. Legs: pale brown. 
This subspecies of P. m. manyar Horsr. from Java was very common indeed on 
the large grassy plains of Upper Siam. Around the town of Chieng Hai for instance, 
numbers of nests belonging to this bird were being built at the time of my visit to this 
place at the beginning of August 1914. The nests were placed either among the high 
elephant grass or in some low trees. The eggs were not laid at the time of my stay there 
and even about three weeks later they did not contain any eggs. 
Fam. Fringillide.

Passer montanus: Schomburgk p. 256; Grant p. 70; Barton p. 106; Williamson I p. 44; Miller p. 386. 
The Malay Tree-Sparrow was very common indeed in Bangkok and in almost every 
town and village of Central Siam and in the Siamese Malaya. 
32. Passer flaveolus. Bryra. — The Pegu House-Sparrow.

The Pegu House-Sparrow is apparently very rare and only confined to the Northern 
parts of the country. However, WILLIAMSON records it from Bangkok, which seems to me 
a little doubtful. 
Outside Siamese territory it has been obtained in the Burmese Provinces and 
Karennee and it is said to occur in Cochin China.
