Overview
Overview
The Shining Sunbeam is a common hummingbird of high Andean shrubland, forest edges, and gardens from Colombia south to Peru and Bolivia. Its warm cinnamon-brown body plumage combined with a metallic coppery sheen on the wings gives the species its descriptive name.
Both sexes are broadly similar in overall pattern, showing rich brownish body plumage set off by the iridescent bronze tones of the back and wing coverts, though males often appear slightly brighter overall.
Identifying the Feather
Feather Identification
- Body feathers: Warm cinnamon-brown across the underparts and much of the body
- Wing/back feathers: Iridescent coppery-bronze sheen, especially visible on the shoulder and back when catching light
- Tail feathers: Often show a rufous or bronzy cast, sometimes with darker tips
- Shaft color: Dark, contrasting somewhat with the warm brown vane color
- Size: Medium-bodied hummingbird, larger than many high-Andes species
- Similar species: The combination of cinnamon body tone and coppery-bronze wing iridescence separates it from other sunbeams and similarly sized Andean hummingbirds
Plumage & Molt
Plumage Details
Adults show warm cinnamon-brown body plumage with a strongly iridescent coppery-bronze sheen across the back, shoulders, and wing coverts. The tail often shows rufous tones. Sexes are similar, though males may show slightly more vivid iridescence. Juveniles are duller and less glossy until completing their first molt. There is no pronounced seasonal plumage variation.
Habitat & Range
Habitat & Range
Shining Sunbeams inhabit high-elevation shrubland, forest edges, hedgerows, and gardens along the Andes from Colombia south through Ecuador and Peru to Bolivia, generally above the tree line or in adjacent transitional habitats. The species is resident, with some local elevational movement following flower availability.
Behavior & Field Notes
Behavior & Field Notes
This hummingbird feeds on nectar from a variety of high-altitude flowering shrubs and trees, and also takes small insects. It is often seen perched on exposed twigs between feeding bouts, a common habit among high-Andes hummingbirds conserving energy in cool conditions. Nests are compact cups placed in shrubs or low trees. Calls include sharp chips and twittering notes used in territorial disputes at flowering patches.
