111bis.- Murray's Vertebrate Zoology of Sind, p. 105.
Length, 9.75 to 10.37; expanse, 20 to 21.5; wing, 6.75 to 7.25; tail, 4.5 to 5.25; bill at front, 0.25 to 0.43; bill at gape, 1.18 to 1.31.
Very similar to G. europaeus, a description of which I give below : :-
Caprimulgus europaeus. :- Plumage above and that of the throat ashy-grey, thickly streaked and spotted with brown, mostly of a yellowish tinge ; head and neck with longitudinal blackish streaks; a white stripe beneath the base of the lower mandilble extends along each side of the lower part of the head, and there is a central patch upon the throat; primaries, secondaries, and tertiaries dark-brown; the outer webs blotched with reddish-brown and the three exterior feathers with a large white patch near the tips of the inner webs ; tail irregularly marked and indistinctly barred with blackish-grey and yellowish-brown; the two external feathers on each side white at their termination;' plumage of under parts yellowish-brown ; tarsi paler ; female like the male, the white spots on the quills and tail feathers absent. The following is a description of G. unwini: :- This species has the upper three-fourths of the tarsus feathered in front.
In both sexes the two outer feathers on each side are tipped with white, but the tippings are about 1.55 and 1.0 broad in the male on the outer and penultimate feathers respectively, and only about 0.75 and 0.44 in the female, and in the latter sex the white is less pure; both sexes have a white spot on the inner webs of the first three, and a corresponding one on the outer webs of the second and third primaries; but here again, while the spots on the inner webs of the male are about one inch broad, those of the female are about half the size.
Within our limits, this Night-jar has only been obtained in Sind, where it is very common.
