trees, or climbing round them in search of minute insects, ants, and small caterpillars, which constitute their chief food. 

 The males utter at times a low harmonious note, which the females respond to by a simple repeated note. The nest is 

 formed on the ground at the base of the large trees, and the female generally deposits five eggs.

Bill rather strong and broad at the base, with the culmen straight and keeled at the base, and the 

 apical part curved, and the sides compressed to the tip, which is emarginated ; the gonys very long and 

 ascending ; the nostrils lateral, and placed in a broad membranous groove, with the opening anterior, 

 oval, and exposed. Wings moderate and rounded, with the fourth, fifth, and sixth quills equal and 

 longest. Tail short and rounded. Tarsi very long and slender, with the front covered with broad 

 scales. Toes long, with the outer toe longer than the inner and united at the base, the hind toe very 

 long ; the claws moderate, compressed, and curved, that of the hind toe very long, much curved, and 

 acute. 



It is in the tropical parts of America that the species of this genus are found : they reside in the forests, and arc usually 

 observed on the ground in the neighbourhood of large ant-hills, the inhabitants of which constitute their chief food. 

 They run very actively on the ground, and their cry is very acute, and is heard before that of other birds at the break 

 of day. The female usually deposits two eggs on a bed of dried leaves collected together on the ground at the base of 

 a large tree. 



Established by Vieillot in 18l6 (Analyse, $c, p. 48.). Myioturdus of M. Boie (1826) and Chamwza of Vigors (1825) are synonymous.
