Description
The gilded sapphire is long and weighs . Both sexes have a medium length, straight, coral red bill with a black tip. Adult males are mostly iridescent golden-green, with a pale rufous chin and a glittering golden-bronze tail. Adult females are almost the same, but duller overall and with a grayish lower belly. Juveniles are like the adult female with buff fringes on the feathers of the head.[Schuchmann, K.L., G. M. Kirwan, and P. F. D. Boesman (2020).

Distribution and habitat
The gilded sapphire is found in northeastern to south central Bolivia, essentially all of Paraguay and Uruguay, central and southeastern Brazil, and northern Argentina. It inhabits open landscapes such as savannah with scattered trees, the edges and clearings of forests, plantations, and gardens. It is most numerous at elevations between . It is regularly found down to and up to , and locally even higher.[

Behavior
Movement
The gilded sapphire appears to be generally sedentary, but it is migratory in parts of Brazil and adjacent Boliva. Its movements elsewhere, if any, are poorly understood.[
]
Feeding
The gilded sapphire forages for nectar at a wide variety of native and introduced plants, shrubs, and trees. It seeks nectar at all levels of its habitat. In addition to nectar the species feeds on insects caught by hawking

Breeding
The gilded sapphire's breeding season in Brazil spans from September to February but has not been defined elsewhere. It builds a cup nest of plant seed fibers and cobweb with lichen and bits of leaf on the outside. It typically places it somewhat exposed on a thin horizontal branch or in a fork about above the ground, but occasionally as high as . The female incubates the clutch of two eggs for 14 to 15 days and fledging occurs 20 to 28 days after hatch.[

Vocalization
The gilded sapphire's song is "a repeated high-pitched, cricket-like trill of variable length". Its call is "a short dry rattle 'trrrt'."[

has assessed the gilded sapphire as being of Least Concern. It has a very large range and though its population size is not known it is believed to be increasing. No immediate threats have been identified.[ It is considered very common throughout its range and it "readily accepts man-made habitats such as gardens and plantations ndrange expansion can be expected."][
