(768) Dicrurus macrocercus minor Layard.
THE CEYLON BLACK DRONGO.
Dicrurus macrocercus minor, Fauna B. I., Birds, 2nd ed. vol. ii, p. 358.
This race is confined to Ceylon only, and with the present breeding material available for comparison it is impossible to say whether it extends into South Travancore, though this seems probable. Except that it is not such a common ubiquitous bird as our Indian races, there is nothing to be said about the breeding of this race.
Wait says that it is not uncommon in the Jaffna Peninsula and the coastal region of the Mannar district, and that it frequents open and cultivated lands as well as scattered thorny jungle.
In Ceylon the breeding season is from March to May, while in Travancore—if the bird there is minor—the season seems to be March and April.
In Ceylon it lays two or three eggs only, while the Travancore bird lays three, and once Bourdillon took a four.
Twenty-one Ceylon eggs average 24.2 x 18.1 mm. ; sixteen from Travancore average 24.5 x 18.4 mm., which would seem to show that the birds laying them are very much nearer in size to the Ceylon than to the Northern bird : maxima 27.0 x 19.0 and 26.1 x 19.2 mm. ; minima 22.8 x 18.9 and 24.4 x 17.2 mm.
I have seen no pure white ones among either the Ceylon or Travan¬core eggs.
