Black-hooded Sunbeam occurs in the Andes of northern Bolivia in La Paz, Cochabamba, and northwestern Santa Cruz (Bond and Meyer de Schauensee 1943, Fjeldså and Krabbe 1990, Hennessey et al. 2003.)
The primary elevational range of Black-hooded Sunbeam is 2500-4200 m, although there are records to as low as 1800 m (Fjeldså and Krabbe 1990, Hennessey et al. 2003). This sunbeam also may have elevational movements (Hennessey et al. 2003).
