Zeledon's antbird (Hafferia zeledoni) is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Colombia, Costa Rica, Ecuador, Nicaragua, and Panama. Zeledon's antbird is 17 to 20 cm (6.7 to 7.9 in) long and weighs about 40 to 56 g (1.4 to 2.0 oz). Both sexes have a wide pale blue ring around their eye and a deep red iris. Adult males of the nominate subspecies are mostly black with variable amounts of white on the wing and wing coverts; the white is almost always hidden. Adult females are mostly dark brown that is paler on their underparts than above. Their lores and face are black. Males of subspecies H. z. berlepschi have more white on their wings than the nominate. Females are a paler and brighter brown than the nominate. In both subspecies the immature males look like adult females. Zeledon's antbird has a disjunct distribution. The nominate subspecies is found from Río San Juan Department in far southern Nicaragua south through Costa Rica into Panama as far as Coclé Province. In Costa Rica it occurs mostly on the Caribbean slope and much less frequently on the Pacific slope. Subspecies H. z. berlepschi is found from eastern Darién Province in Panama south on the Pacific slope through Colombia to western Loja Province in southwestern Ecuador. The species inhabits the understorey and edges of humid evergreen forest and mature secondary forest in the foothills. It mostly occurs in regenerating landslides and tree-falls on steep hillsides and ravines. In elevation it ranges between about 250 and 1,750 m (800 and 5,700 ft) in Central America though in Costa Rica mostly above 500 m (1,600 ft) on the Caribbean side and 900 m (3,000 ft) on the Pacific side. In Colombia it occurs between 100 and 1,600 m (300 and 5,200 ft) and in Ecuador mostly below 1,400 m (4,600 ft) but locally to 2,000 m (6,600 ft).
