 dark streaks ; crown and nape brown, with broad rufous edges to 

 the feathers ; a streak running back above the ear-coverts, and a

 with some feathers round the orbit dark brown ; rest of sides of 

 head white, with a few dark shafts beneath the eye; upper 

 plumage from the nape brown with an ashy tinge; quills the 

 same ; inner webs of primaries, except near the end, with broad 

 white bars ; tail brown, middle feathers unbarred and pale-tipped,
