(1001) Aethiopsar grandis grandis (Moore).
THE SIAMESE YELLOW-BILLED JUNGLE MYNA.
Aethiopsar grandis grandis, Fauna B. I., Birds, 2nd ed. vol. iii, p. 59.
This Jungle Myna occurs in South-West Burma, Eastern Burma as far North as Karenni and the South of the Southern Shan States and South to Mergui ; East of Burma it is found in Siam and Cochin¬ China and has been recorded from Yunnan, where we would have expected the next race, infuscatus.
Although this bird is common in Siam, Herbert’s notes upon its breeding are, as he himself says, unfortunately brief. All he records is the following (Journ. Siam. Nat. Hist. Soc. vol. vi, p. 112, 1923):—“This Myna is found in fair numbers in the paddy fields, but is not nearly so common as G. nigricollis or S. superciliaris. The five clutches in my collection come from Ayuthia, Samkok, Hua Thakae and the Tachin side, and were laid in June and July. The bird is said to lay only in the branch-holes of trees but I found one pair at Sapatoom with a nest in a Palmyra Palm.”
Later Herbert took another clutch on the 12th May.
Beyond the above I can find no notes on the breeding of this bird. The nests found by Herbert contained three or four eggs, generally the former, and these in appearance are just like other Mynas’ eggs, but vary in depth of colour more than most. Two clutches are quite pale, the others being a rather deep blue ; the texture is very smooth, fairly glossed and with no corrugations ; in shape they vary from short, broad ovals to a long, pointed oval.
Twenty eggs average 29.4 x 20.9 mm. : maxima 31.1 x 21.4 and 30.7 x 21.9 mm. ; minima 26.8 x 21.0 and 29.8 x 19.8 mm.
