The generally common Gilded Hummingbird is found in lightly wooded country, including parks and gardens, over central-southern South America, from northeast Bolivia south to Uruguay and northern Argentina. It is a fairly nondescript hummingbird in many respects, with virtually no sexual dimorphism other than the fact that females are slightly duller. Virtually the entire plumage is iridescent golden-green, with a coral-red, dark-tipped bill, a very small white post-ocular spot, and a golden-bronze tail. The species’ overall body color and mainly red bill should easily identify it. The Gilded Hummingbird is presumed to be mainly sedentary, but is considered to be a migrant visitor to the Brazilian state of Mato Grosso, although such movements are still barely understood.
