Canivet's Emerald

Male Canivet's emeralds are 7.8 to 9.3 cm (3.1 to 3.7 in) long and weigh 2.1 to 2.8 g (0.074 to 0.099 oz). Females are 7.5 to 8.6 cm (3.0 to 3.4 in) long and weigh about 2.3 g (0.081 oz). Males of the nominate subspecies have a red bill with a black tip. Their crown is bright golden to golden green and the rest of the upperparts a less brilliant golden green. Their underparts are brilliant golden green with white tibal tufts. The tail is long and forked, blue-black or black with a blue gloss, and the central two or three pairs of feathers have dark brownish gray tips. Voice: What is thought to be the Canivet's emerald song is "an endlessly repeated, characterless wiry tseee tseeree". Its call has been described as "a dry, scratchy chut or chit, sometimes run together into a soft, staccato chatter"
