Warbling Antbird (Hypocnemis cantator) Science Article
Few nests of Amazonian antbirds (Thamnophilidae and Formicariidae) have been described. Here we present nesting records for five species of antbirds found in Tinigua National Park, Colombia. A pouchshaped pensile nest of the Warbling Antbird (Hypocnemis cantator) in a treefall gap within seasonally flooded forest contained two eggs colored like those found in French Guiana but different from those in Amazonian Brazil and Peru.
