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 arid keeled at the base, and 
fl 
apical part curved, and the sides compressed to the tip, which is emarginated ; the gonys very long a 
ascending; the nostrils lateral, and placed in a broad membranous groove, with the opening anteri° r ’ 
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 h r ° a 
scales. Toes long, with the outer toe longer than the inner and united at the base, the hind toe v e1 ^ 
reel, an L 
long ; the claws moderate, compressed, and curved, that of the hind toe very long, much curv 
acute. 
It is in the tropical parts of America that the species of this genus are found : they reside in the forests, and arc 
observed on the ground in the neighbourhood of large ant-hills, the inhabitants of which constitute their clue ^ 
They run very actively on the ground, and their cry is very acute, and is heard before that of other birds at the ^ ^ 
of day. The female usually deposits two eggs on a bed of dried leaves collected together on the ground at the 
a large tree.
