THE CEYLON EMERALD DOVE.
Chalcophaps indica robinsoni Stuart Baker, Bulk B. O. C, xlviii, p. 58 (1928). Chalcophaps indica. Blanf. & Oates, iv, p. 26 (part.).
Vernacular names. Nila robeya (Cing.).
Description. Similar to the preceding form but with the grey of the head and nape running down the hind neck to the scapulars in a well-defined line. It is also a smaller bird.
Colours of soft parts as in the typical race.
Measurements. Wing, 132 to 143 mm., 127 to 134 mm.
Nidification. This Emerald Dove breeds in the forests of Ceylon from January to June, its nidification being just like that of the preceding bird. The eggs are small and two pairs taken by Phillips are almost white; these may, however, be unusual, as Wait records the eggs as pale buff. The few I have measured average 26.1 x 19.9 mm.
Habits. Similar to those of the Indian bird.
