1471. Surniculus lugubris stewarti

(1471) Surniculus lugubris stewarti Stuart Baker.
THE Ceylon DRONGO-CUCKOO.
Surniculus lugubris stewarti, Fauna B. I., Birds, 2nd ed. vol. iv, p. 166.
This subspecies is found in Western India from Karwar in the Bombay Presidency to Ceylon,
Here again our evidence, such as it is, about the eggs of this Cuckoo is very contradictory. Davidson and Bell have both seen Drongos feeding young Drongo-Cuckoos, and the latter has taken eggs from Drongos’ nests which he believes to have been those of the Cuckoo. He describes the eggs as “the same size as those of D. ater, in whose nests they were found, and are similar ; the shape is somewhat abnormal, tending to both ends being somewhat obtuse.” Though this evidence certainly supports that of Rattray, we again have an egg so large that it is contrary to all we know of Cuckoos’ eggs which is really certain.
Wait and Stewart’s Ceylon evidence is stronger. First they both find young Cuckoos in the nests of the Black-fronted Babbler, and then they obtain quite a number of eggs in the same kinds of nests. These are in type much more like the supposed eggs of Surniculus taken by Coltart and Kuschel. The ground is grey-white and they are sparsely speckled and blotched with brown and underlying marks of neutral tint—in fact the eggs are not unlike those of the foster parent.
Three of these eggs measure 19.3 x 14.7, 10.6 x 14.8 and 19.5 x 14.6 mm. A fourth egg taken in a nest of an Iora measures only 17.5 x 13.8 mm.
I think it is almost certain that these eggs will prove to be correct.
The breeding season in Ceylon is from December to May and in Travancore January to March.
