Gorget (bird)

Like many hummingbirds, the male Costa's hummingbird has an iridescent gorget.

A gorget is a patch of colored feathers found on the throat or upper breast of some species of birds.^[1] It is a feature found on many male hummingbirds, particularly those found in North America; these gorgets are typically iridescent.^[2] Other species, such as the purple-throated fruitcrow^[3] and chukar partridge, also show the feature.^[4] The term is derived from the gorget used in military armor to protect the throat.

Feather wear and exposure to the sun can produce changes in the apparent color of iridescent gorget feathers. For example, fresh gorget feathers on the Anna's hummingbird are rose red; these fade to a coppery bronzy color with age.^[5]
