The outer pair of tail-feathers is barred black and white in eleven males 
and largely rufous with a grayish outer web and tip and a single subterminal 
black bar in nine specimens. Both these types of coloration occur in speci- 
mens from the same locality. 
The type has fewer spots in the upper wing-coverts than most of our 
Colombian birds, but I believe this to be due to individual variation. The 
back has, as a rule, but few bars and in six specimens is practically unbarred. 
In six of twenty males there is more or less rufous on the crown (in only one, 
a male from Paramo de Tama, does it form a ‘ patch’), the remaining four- 
teen have the crown dark slaty with essentially no rufous and but little or 
no black on the nape. 
The terminal white areas on the outer primaries are confluent in the 
second or third (or both) quills, in fifteen specimens, disconnected in five 
specimens. 
In the female, rufous appears more frequently in the crown than in the 
male. Only three of fifteen specimens are without it, while in three others 
it forms a well-developed ‘patch.’ Females in juvenal, or nestling plumage, 
are as deeply colored below as the most richly marked males and the streaks 
on the underparts are less sharply defined than in mature birds. On the 
other hand, what I assume to be fully adult birds, are pale fulvous heavily 
streaked with umber below, and the variations between these two extremes 
are doubtless attributable to age. A female from the type-locality is less 
heavily streaked below and less definitely barred on the tail than Colombian 
specimens. !

but male with the sides conspicuously spotted; crown darker, nape blacker, terminal
