Nidification. Messrs. E. Gr. Herbert and W. J. E. Williamson found this bird breeding in Siam, placing its nests in holes of trees standing in Paddy cultivation. One nest found by Herbert was placed in a Palmyra palm. They breed from March to July and lay four eggs, sometimes only three. These are exactly like the eggs of Acridotheres tristis but a little darker blue in tint and are not quite so big. Twenty eggs average 29.4 x 26.9 mm.: maxima 31.0 x 21.4 and 30.7 x 21.9 mm.; minima 26.8 X 21.0 and 29.8 x 19.8 mm.
