1620. Caprimulgus macrourus atripennis

(1620) Caprimulgus macrourus atripennis Jerdon.
THE SOUTHERN LONG-TAILED NIGHTJAR.
Caprimulgus macrourus atripennis, Fauna B. I., Birds, 2nd ed. vol. iv, p. 361.
This Nightjar, formerly called Jerdoni Nightjar, is found in Ceylon and the whole of Southern India in suitable country about as far North as Kanara in the Bombay Presidency on the West and the Godavery Valley on the East.
This is apparently more of a jungle bird than the Common Indian Nightjar, though it prefers open forest without much undergrowth. It also often frequents bamboo and scrub-jungle, even round villages, and occurs throughout the plains and in the hills up to some 4,000 feet or in Ceylon, according to Wait, up to 3,500 feet.
The only note in Hume’s ‘Nest and Eggs’ is that of Legge, who says that it breeds in the West of Ceylon during the latter part of the dry season in April and May. Davidson took numerous eggs in Kanara in March and early April ; Kinloch obtained a pair in the Nelliampathy Hills in February and I have a pair of eggs taken in Khandesh in July.
Although superficially it seems impossible to separate this bird from the macrourus group, its eggs, just as well as its voice, habits etc., are quite unlike any other macrourus eggs. The ground varies from a very pale cream to a rather dark dull buff, while the marks consist of blackish-brown spots scattered irregularly over the whole surface ; occasionally the spots are more reddish-brown but, what¬ever they are, they stand up boldly and clean-cut against the ground. Some eggs have a few specks also scattered about of the same colour as the spots, though these are unusual, but there are no secondary markings, no lines and no marblings. In one egg only I have seen two smudgy blotches of pale sepia with a darker outline.
In shape they are rather broader ellipses than is usual with Nightjar’s eggs.
Twenty-five eggs average 30.1 x 22.2 mm. ; maxima 81.3 x 23.5 mm. ; minima, 29.0 x 22.0 and 31.1 x 21.1 mm.
