Ilahits. Schoniburgk states (Reis. Guian. iii. ]\ 674)' that this 

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

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

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

 ease and great rapidity through the branches of the undergrowth. 

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

 the Savannas. Its food consists chiefly of insects.
