About the Black-hooded Sunbeam

The black-hooded sunbeam (Aglaeactis pamela) is a species of hummingbird in the "brilliants", tribe Heliantheini in subfamily Lesbiinae. It is endemic to Bolivia. The black-hooded sunbeam is monotypic. The black-hooded sunbeam is about 12 cm (4.7 in) long including its 15 mm (0.59 in) straight black bill. Males weigh about 5.2 g (0.18 oz) and females 5.8 g (0.20 oz). The adult male is mostly purplish black, with glittering golden green to bluish green on the lower back and rump and a white tuft in the center of the breast. The tail is rufous with dusky tips to the feathers. Adult females are colored like the male but are duller overall and with less iridescent lower back and rump. Juveniles are somewhat browner than adults, with a reduced breast tuft and an olive cast to the tail.
