ANTROSTOMUS SATURATUS Salvin. 



DUSKY WHIPPOORWILL. 



Adult male. — General color sooty black, but this much broken by 

 rather small spots (mostly transverse) of cinnamon-rufous, the pileum, 

 however, with several broad, irregularly serrated stripes of uniform 

 black, and, sometimes, with an admixture of whitish, barred with 

 black, on lateral portion, the scapulars with the black disposed in 

 the form of large, irregular spots or blotches, these sometimes more 

 strongly relieved by adjoiniag mottlings of pale rusty buff; outer 

 webs of primaries with rather small but distinct spots of cinnamon- 

 rufous; four middle rectrices sooty black with about ten broad 

 y\-shaped bars of cinnamon-rufous, averaging decidedly narrower 

 than the black interspaces (except on middle pair) and themselves 

 more or less broken by irregtdar small blotches of black; three outer- 

 most rectrices (on each side) broadly tipped with white, the cinnamon- 

 rufous bars much narrower, less broken, more directly transverse, and 

 becoming obsolete on distal portion, the white tips about 20-25 mm. 

 wide (measured along shaft) on the third and f oxirth (from middle) but 

 narrower on the fifth (outermost), on which the white is of less extent 

 on the outer web than on the inner; sides of head and neck and 

 general color of under parts sooty black, each feather with a terminal 

 pair of small cinnamon-rufous roundish or transversely oval spots, 

 these larger, and in form of V-shaped bars, on lower throat, but not 

 forming a distinct patch or band; middle of breast with several larger 

 spots of dull buffy whitish, the posterior imder parts with broad bars 

 of dull ochraceous-buff (broadest on imder tail-coverts), the flanks, 

 or posterior sides, and abdomen crossed by a broken band of large 

 spots of buff or buffy whitish; imder wing-coverts sooty black, 

 indistinctly spotted on outer margin of wing with dark rusty; inner 

 webs of primaries uniform dark sooty slate color; bill dull black; 

 iris dark brown; feet dusky, the tarsi becoming paler (duU flesh color 

 in life) on upper and posterior portions; length (skins), 212-230 

 (221); wing, 153-158.5 (155.6); taU, 115-122 (117.7); exposed cul- 

 men, 12.5-13.5(13); tarsus, 14-16 (15.2); middle toe, 15-15.5 (15.2)." 



AduU female. — Similar to the adidt male but the general "tone" 

 of coloration rather lighter, owing to the somewhat greater relative 

 size of the cinnamon-rufous markings and their lighter color, espe- 

 cially on upper parts, and with the three outer rectrices (on each side) 

 more narrowly tipped with light ochraceous-buff, instead of white; 

 length (skins), 220-230 (224); wing, 153-159 (156); tail, 117-120.5 

 (119.2); exposed cuhnen, 11-12.5 (11.8); tarsus, 15.5-16.5 (16); 

 middle toe, 15.5-16 (15.8).*
