Eye bright chestnut ; bill black ; feet pinkish white. 
This species was not noted below Caicara. but was observed on 
the upper river as far as I extended my explorations. It inhabits the 
thick forest, and while not rare it is more often heard than seen. It 
has a high flute-like whistle that is very difficult to trace. Birds may 
be very near, concealed in the thick underbrush, but as they walk 
rapidly away from one, the call notes seem to ccmie from half a dozen 
different directions. I have never seen them anywhere except on the 
ground where they walk and run easily and gracefully over the fallen 
ileaves, and when flushed fly but a short distance and again drop to 
the ground. 
In the American Museum collection is a series collected by 
Klages at Suapure and Maripa on the Caura River.
