Rufous-webbed brilliant

The rufous-webbed brilliant (Heliodoxa branickii) is a species of hummingbird in the "brilliants", tribe Heliantheini in subfamily Lesbiinae. It is endemic to Peru.

The rufous-webbed brilliant is 11 to 11.5 cm (4.3 to 4.5 in) long. Males weigh about 5.8 g (0.20 oz) on average and females 5.4 g (0.19 oz). The species' English name comes from its cinnamon-rufous inner wing feathers; the rest of the wing is dusky. Both sexes have a black bill whose mandible base is paler. Males are mostly shining dark green. Their forehead is brighter glittering green and they have an iridescent rosy gorget. The undertail coverts are bright white. The central pair of tail feathers are green and the rest dark blue. Females also have shining dark green upperparts, flanks, and breast. They have a short white streak from the bill to below the eye. The throat and breast are white, with shining green tips to the feathers, and the belly is white to buffy. A gorget is often lacking, and when present is paler and yellower than the male's. The undertail coverts are bright white like the male's, but the blue outer tail feathers have white tips.
