(1630) Caprimulgus asiaticus Lath.
THE COMMON INDIAN NIGHTJAR.
Caprimulgus asiaticus, Fauna B. I., Birds, 2nd ed. vol. iv, p. 372.
This Nightjar is found over the greater part of Ceylon, India and Burma, in the last country as far South as Tenasserim. In India it is absent from some of the driest areas such as the deserts of Rajputana and Sind, though even in the latter country Sir Evan James recorded it as not uncommon about Sehwan. Herbert also found it breeding near Samkok and Bangkok in Siam.
The birds breed in almost any kind of country other than actual forest and at all elevations from the plains to about 6,000 feet. Its eggs have been taken in open uncultivated waste land, bare and stony, dotted with small shrubs or covered more or less with short stubbly grass. Sometimes they have been found in fallow-land or in low crops ; often in thin bush or in thatching grass-land ; at other times in thin mixed scrub or bamboo-jungle and not in-frequently even in deciduous forest. Major Cook records finding them in a “thick, dark piece of jungle” ; Thompson found them “in a quite unsheltered spot in the middle of a dry pebbly nullah and sometimes at the base of a dead wall.” In Siam Herbert once found a pair breeding in a garden but, generally, in open waste land or in scrub-jungle.
Over the whole of the area occupied by this Nightjar there seems to be two regular seasons, first March and April, and secondly the middle of June to the middle of August. At the same time eggs may be found in almost any month of the year. Herbert in Siam, Venning in Burma and myself in Bengal have taken eggs as early as February Davidson found them still breeding freely during September in Kanara, and I have beard of odd clutches being taken in January and November.
The eggs, except for being so much smaller, are just like those of macrourus, pale stone-cream to deep salmon-buff in ground¬colour, with the normal primary blotches of red and reddish-brown, with others underlying of pale grey and pinkish-lavender. An egg taken by Wait in Ceylon is very handsome, the ground is a bright pale salmon, while the primary marks consist of a few huge blotches and smaller specks of deep chestnut-red and still larger secondary ones of pale lavender-pink. A pair taken by Herbert is a great contrast to this, the markings being almost invisible, the whole egg appearing to be a rather bright terra-cotta brick-red.
One hundred eggs average 26.5 x 10.9 mm. : maxima 28.3 x 20.7 and 28.2 x 21.0 mm. ; minima 24.0 x 20.0 and 26.2 x 18.3 mm.
