Adult male. Above brown in different shades, finely mottled with 

 darker brown, sometimes rather greyish brown, often rather rufous ; 

 top of the head with longitudinal black spots, bolder in the centre 

 of the crown, where they form a long stripe; ear-coverts golden 

 buff ; scapulars with large black spots, chiefly on the outer webs, 

 and broadly bordered with bright buff; primaries deep brown, 

 with a broad white band across the first four or five, often indistinct 

 on the fifth, and more or less fulvous on the outer webs ; wing- 

 coverts with terminal buff spots ; outermost pair of rectrices deep 

 brown, with a more or less developed white streak on the inner 

 webs, the next pair white, more or less dusky on the outer webs ; 

 the following pair white, inclining to buff, barred with dusky near 

 the base and on a great part of tlie outer webs, this coloration 

 varying in extent ; lower parts buff, regularly barred with dusky, 

 darker on the breast ; a broad white band across the throat, some- 

 times almost interrupted in the middle. Total length about 10 to 

 11 inches, wing 5-7 to 6-9, tail 5-7 to 6-G, tarsus 0-9 to 1-1. 



Adult female. Similar to the male, but smaller, the markings 

 duller and therefore not so beautifully contrasted, the band across 

 the primaries not pure white, but more or less shaded with buff ; 

 outer rectrices barred with buff, only the tips of the next two pairs 

 white. Wing 5-G to 6-5 inches, tail 5-4 to 6. 



Young. Colours duller, the abdomen not so distinctly barred as 

 in adult individuals ; white on the tail less in extent ; white on the 

 primaries less pure ; head not so boldly streaked, but with drop-like 

 spots, surrounded by light grey. 



The nestling is covered with buff down, darker above. 



This species, like many Goatsuckers, varies greatly in colour and
