- A. c. regalis:
- Andes of central Peru (Huánuco, Pasco and Junín) - Northern White-tufted Sunbeam
- A. c. castelnaudii:
- Andes of south Peru (Huancavelica, Ayacucho, Apurímac, Cuzco) - Southern White-tufted Sunbeam
Habitat
Found in patches of evergreen montane forest, especially common in Escallonia and Polylepis forest with flowering vines.
Usually in drier zones and at much greater altitudes than Shining Sunbeam. Occurs at 3500 to 4300 m, rarely up to 4600m.
Behaviour
Diet
Feeds on nectar from flowers of Barnadesia, Berberis, Brachyotum, Centropogon, Labiatae, Lupinus, Salpichroa and Siphocampylos.
