Viridian Dacnis is endemic to the border region of northwestern Colombia and southeastern Panama, where it is generally rare. In Colombia, it occurs on the Caribbean slope on both sides of the Gulf of Urabá, and east to the Sinú Valley; on the Pacific slope, it is reported from the Jurado and Salaquí Valleys (Meyer de Schauensee 1951, Haffer 1975, Hilty and Brown 1986). These localities are in western Cordoba, northwestern Antioquia, and northern Chocó). In Panama, it is restricted to eastern Darién (Wetmore et al. 1984, Ridgely and Gwynne 1989). A sighting was reported from El Real, Darién on 13 Januay 1978 (Wetmore et al. 1984). It is probably most common in Jurado, Chocó on the Pacific base of Serranía de los Saltos (Fundación ProAves 2011). In Panama, they are found in Darien National Park and in Cana in the Cerro Pirre foothills (Fundación ProAves 2011). This species is generally in the lowlands to 600 m elevation, up to 700 m, and is perhaps more common in foothills than lowlands (Isler and Isler 1987, Ridgely and Tudor 1989, Restall et al. 2007).
