 and ramp black, covered with wavy white lines ; the interscapular 

 region usually washed with reddish brown ; wing-coverts and scapulars 

 reddish brown, finely mottled with black ; primaries, primary-coverts, 

 and secondaries dark brown, the latter largely mottled with reddish 

 brown on the outer web ; the basal part of the outer web of the third

 of the marbled white band on the tail. 



A quite young male has most of the upper parts dull reddish brown 

 thickly mottled with black, a few feathers on the mantle have the 

 ground-colour grey, and the upper tail-coverts are widely tipped with 

 white ; the wing-coverts, scapulars, and secondaries have whitish- 

 buff tips extending for some distance up the shaft, and the second- 

 aries are also irregularly mottled along the outer margin with pale 

 buff ; chin and throat whitish, neck mottled with black, chest and 

 breast rufous-buff intermixed with a few black feathers ; rest of 

 underparts dirty white more or less mottled with dusky ; tail- 

 feathers dull brownish red, with marbled bars and tips of buff.
