The topazes are two species of hummingbirds in the genus Topaza. They are found in humid forests in the Amazon Basin. Males are by far the largest hummingbirds in their range – the giant hummingbird of the Andes is the only larger species in the family. Males have a total length of about 22 cm (8 ⁄4 in), although this includes their elongated rectrices. They are very colourful, being mainly strongly iridescent golden and crimson with a black hood and a green throat. Females lack the elongated rectrices and have a mainly green plumage.
