Habits. Scbomburgk states (Reis. Guian. iii. p. 674)'"that this 

 is a shy bird and that it inhnbits the Savannas, where it may be 

 seen in pairs on the low Cnratella-trees or on the ground beneath 

 isolated bushes. It is most agile, and crefeps with astonishing 

 ease and great rapidity through the branches of the undergrowth. 

 He had the greatest trouble in procuring a specimen, for as 

 soon as it discovers what it thinks to he a suspicious object, it 

 keeps up a scratching noise. It nests in low bush or small trees in 

 the Savannas. Its food consists chiefly of insects.
