all of which vary from a light buff (even almost white on edges of 
scapulars) to rich fulvous. These variations are probably due to age, 
the parts becoming darker with @Ecessive molts. In two females from 
Mariveles, Luzon, the buff spot on first primary does not reach the shaft.

“Adult male-—Similar to Caprimulgus affinis but differing as follows: 
General coloration darker. Upper parts hair-brown, finely vermiculated 
and dotted with clove-brown, light gray, and black; scapulars marked with 
broken spots of cinnamon; first- four primaries barred across their middle 
with pure white except the outer web of the first primary, this band 
varying from 12 to 24 mm. in width on the differing feathers, widest on 
the fourth; outer tail-feather white only on the terminal half, the basal 
half being cinnamon, clouded and irregularly cross-banded with brownish 
black, and the tips of both webs clouded with brownish black; second 
feather similar, but with much less of the dusky clouding at tip; lower 
abdomen and thigh-coverts cross-banded with pale sepia-brown; under 
tail-coverts and anal region buff, without cross-bands; upper third of 
tarsus feathered. Length of skin, 205; wing, 163; tail, 100; culmen, 8; 
tarsus, 19. 
“Individuals vary greatly in the character and size of the punctate 
and vermiculate markings of the upper surface. The vague black cross- 
bands of the middle pair of tail-feathers are somewhat V-shaped (open 
apically), numbering about eight. 
“In true affinis, adult males have the outer tail-feather all white, 
and the lower abdomen, thigh-coverts, and under tail-coverts ‘uniform 
pale fulvous buff.’ In C. affinis griseatus the bars are spread over the 
whole of the lower abdomen, thighs, and lower tail-coverts, and the color 
is more grayish rufescent than in C. affinis mindanensis, which appears 
to be closest to the form of C. affinis inhabiting Celebes.” ( Mearns.)
