788. Dissemurus paradiseus rangoonensis

(788) Dissemurus paradiseus rangoonensis (Gould).
Dissemurus paradiseus rangoonensis, Fauna B. I., Birds, 2nd ed. vol. ii, p. 378.
This is the Central Burmese form, found North of the last race and occurring North as far as Pakokku, the Lower Chindwin and South Shan States. North again of this there is an intermediate area in which the birds merge gradually into D. p. grandis but, when one gets into the Northern Chin Hills, Kachin Hills, Bhamo, Northern Shan States and Yunnan, we can say quite definitely that the birds are all grandis.
Oates obtained the nests of this Drongo in Pegu, and it is one of the few of which he gives a description at all full. He writes :— “I have taken the eggs of this species on all dates from the 30th April to the 16th June.
“The nest is placed in forks of outer branches of trees at all heights from 20 to 70 feet, and in all cases they are very difficult to take without breaking the eggs.
“The nest is a cradle, and the whole of it lies below the fork to which it is attached. It is made entirely of small branches of weeds and creepers, finer as they approach the interior. The egg-cup is generally, but not always, lined with dry grass.
“The outside dimensions are 6 inches in diameter and 3 deep. The interior measures 4 inches by 2. In one nest the sides are bound to the fork by cotton-thread, in addition to the usual weeds and creepers.
“The eggs have very little or no gloss, and differ among them¬selves a good deal in colour. In one clutch the ground is white, spotted and blotched, not very thickly, with neutral tint and inky purple, chiefly at the larger end. Other eggs are pinkish-salmon, and the shell is more or less thickly or thinly covered with pale greyish-purple or neutral tint and brownish-yellow, or orange brown spots and dashes.”
Cook obtained eggs, which he gave me, in the lower Chin Hills on the 25th April and Hopwood found several nests near Rangoon and the Lower Chindwin in April and May.
There is little to add to Oates’s account. Nests and eggs differ in no way from those of D. p. paradiseus, and the few eggs I have seen are all of types already described under that form.
As regards the breeding season, Oates’s period, 30th April to 16th June, must be extended back to 25th April, but otherwise embraces the dates of all the nests of which I have any record.
The number of eggs laid is three or four.
Eighteen eggs average 27.6 x 20.3 mm. : maxima 31.0 x 22.0 mm. ; minima 24.5 x 20.0 mm.
