The shining sunbeam (Aglaeactis cupripennis) is a species of hummingbird in the "brilliants", tribe Heliantheini in subfamily Lesbiinae.

Their throat is rufous dotted with dusky gray, the breast a patchy buff, and the belly reddish brown.

[6] The nominate subspecies of shining sunbeam is found in all three Andean ranges of Colombia and south from there through Ecuador to Peru's departments of La Libertad and Huánuco.

[6] The species inhabits sub-páramo to páramo, landscapes characterized by grasslands with scattered shrubs and trees.

It feeds at a wide variety of bromeliads, vines, and trees including Embothrium, Puya, and Fuchsia, and males defend patches of flowering plants.

It builds a compact cup nest of moss and cobweb lined with soft plant fibers and sometimes decorated on the outside with bark or lichen.

[1] It is generally fairly common, occurs in a wide range of habitats, and is found in several protected areas.
