"The sexes are alike in size and color. Young birds are rather more 

 rufescent below and have the streaks on the head tinged with rufous. 

 Both specimens collected by Doctor Steere had the iris hazel, but Mr. 

 Everett gives the iris as white in all those obtained by him." (Sharpe.) 



"This species seems to be confined to the Island of Basilan, where it 

 is extremely common in the forest and second growth. It works about 

 the dense tangle of vines, and usually keeps within five to ten meters of 

 the ground. Thirteen males average: Length, 134; wing, 60; tail, 54; 

 culmen, 16; tarsus, 18; middle toe with claw, 18. Eight females, length,
