Rufous-vented Whitetip

The rufous-vented whitetip is 9 to 10 cm (3.5 to 3.9 in) long and weighs 4 to 4.2 g (0.14 to 0.15 oz). Both sexes have a medium-length straight black bill and a prominent white stripe behind the eye. Both have shining green upperparts and a forked tail, though the female's is not as deeply indented as the male's. Males have shining green underparts with buffy undertail coverts. The tail is dusky bronze; the central feathers have wide white tips. Females have white underparts spotted with green. The tail is dusky bronze with white tips on the outermost feathers. Voice: The rufous-vented whitetip makes a "mellow, fast twittering 'tweetweetweetwee...'" that can sound like "a laughing chatter". While feeding in flight it also makes "a single lower-pitched scratchy note 'tzrrrrr'".
