fuscous-black; other tail feathers with long attenuated narrowly pointed 

 tips extending far beyond (75 mm. or more) the central rectrices, dark 

 dull olive-brown in color, with lengthwise irregular and incomplete wavy 

 markings of tilleul buff on the outer webs and close to the shafts on 

 the iimer webs, these pale markings reduced or almost absent on the 

 protruding narrow terminal portions of the feathers; lores, circumocular

 gape to the front and below the eye ; lower eyelid largely whitish ; cheeks 

 whitish splotched and speckled with mximmy brown ; chin and upper throat

 with dark huffy brown to dark olive-brown; two large bare gular sacs 

 on lower throat completely surrounded with white feathers with narrow 

 mummy brown tips ; posterior to these feathers on each side, but not on 

 the midventral area, are patches of very stiff, short, white feathers with 

 strong yellowish-white shafts and reduced white vanes; on each side of 

 neck is a patch of fluffy, soft, long, white feathers, and at the anterior 

 end of this are a number of long black hairlike feathers, the shortest 

 about 75 mm. and the longest twice that length (by July these are worn 

 down to mere stubs, but in fresh nuptial plumage they are very striking) ; 

 breast feathers long, white, tipped with fuscous-black and with narrow 

 blackish shafts, some of which protrude beyond the vanes giving a hair- 

 like appearance, the more anterior of these feathers with the blackish 

 "tips" actually terminally edged with white and very small in size, the 

 more posterior ones with no such white edges and w4th the dark spots 

 large; sides with the upper (dorsal) vane of the feathers similar to 

 those of the back but with a coarser pattern, the lower (more ventral)

 and upper throat without dusky brown specklings, the lower throat and 

 breast light pinkish buff crossed with narrow bars of blackish, the posterior
