Pirre Hummingbird is resident in eastern Panama and in adjacent northwestern Colombia. In Panama it is reported from several ridges in eastern Darién: Cerro Sapo, the Serrania de Jungurudó, and Cerro Pirre (Wetmore 1968, Ridgely and Gwynne 1989, Angehr et al. 2004). In Colombia it occurs in northwestern Chocó, adjacent to the border with Panama (Wetmore 1968, Hilty and Brown 1986).
The elevational range of Pirre Hummingbird is from 600-1650 m (Parker et al. 1996), although on the eastern slope of Cerro Pirre it is most common between 1100-1275 m (Robbins et al. 1985).
