1108. Passer flaveolus

(1108) Passer flaveolus Blyth.
THE YELLOW-BELLIED Sparrow.
Passer flaveolus, Fauna B. I., Birds, 2nd ed. vol. iii, p. 182.
This Sparrow is resident all over Burma from Arrakan on the West and from the Shan States on the East as far South as Prome in Tenasserim. East it occurs throughout Siam, Annam and Cochin China.
Oates found this bird breeding very commonly in Pegu both in houses and in holes in trees. In Siam Herbert and Williamson obtained series of eggs from holes in trees “nearly all in trees standing in rice cultivation,” but the latter also had the bird breeding in his garden both in holes in trees and in the thatch of outhouses. Harington, Wickham, Mackenzie, Cook and Hopwood, who all saw many nests of the Yellow-bellied Sparrow, found it more of a Tree-Sparrow than a House-Sparrow, though they took a certain number of nests from thatched roofs of bungalows and also one or two from niches on rafters under the thatch.
The nests are described as just like those of the Tree-Sparrow, a miscellaneous assortment of grass, leaves, roots and other odd¬ments, always well lined with feathers. Sometimes the nests were very bulky, sometimes rather scanty, but the lining never varied.
April is undoubtedly the month in which most eggs are laid, but I have others given to me by various collectors, taken in each month from February to July, while probably eggs are laid occa¬sionally in any month of the year.
* Although this bird has long been known as the "Pegu House-Sparrow,” this name may confuse, as there are other House-Sparrows in Pegu, whilst the bright yellow belly at once separates this Sparrow from others.
The eggs number three or four, sometimes two only, and are in appearance like other Tree-Sparrow eggs. In one clutch of four taken by Mackenzie in Maymyio there is one pure white egg, one almost black, the dense stippling covering the whole ground, while the two remaining eggs are mottled grey.
Eighty eggs average 18.6 x 13.9 mm, : maxima 21.0 x 14.2 and 19.2 x 15.2 mm. ; minima 16.1 x 13.8 and 17.0 x 12.9 mm.
As is usual with all Tree-Sparrows, both parents often stay in the nest together and when the young are hatched the whole family sleep in it. The male has a little twittering chirp which he sings to his wife when she is sitting, often giving away the site of the nest by so doing.
