Tepui goldenthroat

The tepui goldenthroat (Polytmus milleri) is a species of hummingbird in the subfamily Polytminae, the mangoes. It is found in Brazil, Guyana, and Venezuela.

The tepui goldenthroat is 11 to 12 cm (4.3 to 4.7 in) long. Males weigh 4.5 to 6.1 g (0.16 to 0.22 oz) and females 4.1 to 5 g (0.14 to 0.18 oz). Males have bronzy green upperparts and glittering green underparts. The tail is shades of green with a wide white band at the base and white tips. The area around the eye is dusky gray with white streaks above and below it. The female is smaller than the male and has dull white underparts heavily dotted with golden-green, especially on the breast. Juveniles are like the adults but with buffy edges to the head's feathers.
