August 3, 2025 - Rufous-capped Antthrush (Formicarius colma) Found in parts of Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela, these antthrushes live in lowland forests and swamps. They have been recorded feeding on ants and grasshoppers, generally foraging alone on the forest floor in leaf litter and on logs, often around the edges of army ant swarms. They probably build cup-shaped nests in cavities, though few have been found. Females lay clutches of two eggs.

These antthrushes are found in forests in parts of Costa Rica, Panama, Colombia, and Ecuador. They eat arthropods, tiny reptiles, and frogs, foraging alone or sometimes in pairs on the forest floor. Breeding between December and May, depending on the area of their range, they build shallow cup-shaped nests from leaf stems and dry leaves in hollow palm stumps.

These antthrushes are found in parts of Costa Rica, Panama, Venezuela, Colombia, Ecuador, and Peru. Foraging alone or in pairs, they sometimes follow army ant swarms, but little else is known about their diet. They sing their whistled, two-part song from the forest floor. Their breeding habits are virtually unknown, though a bird was found in breeding condition during the month of June in Colombia.

This family contains just 8 eligible species in two genera (Formicarius and Chamaeza).
