Chlorospingus flavovirens occurs on the lower Pacific slopes of the Andes in north-west Ecuador (Esmeraldas and Pichincha) and south-west Colombia (Nariño and Valle del Cauca¹⁶). In Esmeraldas, it is known from El Placer, Awacachi Corridor⁹, Alto Tambo¹⁵, Cotacachi-Cayapas Ecological Reserve^10,11, and the Canandé Reserve¹². In Pichincha, it occurs along the Milpe road⁹. In Colombia, there is a cluster of four sites in Nariño and two sites in Valle del Cauca (also close to each other), and there are large areas of mostly intact habitat between these two areas^4,5. It is fairly common to common at a few localities⁴.
