Purple-bibbed Whitetip
Urosticte benjamini
The purple-bibbed whitetip is 8 to 9 cm (3.1 to 3.5 in) long and weighs 3.8 to 4.2 g (0.13 to 0.15 oz). Both sexes have a medium-length straight black bill and a prominent white stripe behind the eye. Both have glittering green upperparts. Males have a violet lower throat white below it and a grayish belly with green spots. The tail is dusky bronze; the central feathers have wide white tips that appear as an oval spot. Females have white underparts heavily spotted with green. The tail is dusky bronze with purple near the end and white tips on the outer feathers. Voice: The purple-bibbed whitetip makes a "mellow, nasal-sounding fast twittering 'tweetweetweetwee...'" that can sound like "a laughing chatter". While feeding in flight it also makes "single lower-pitched scratchy notes, 'chrrrrr'". Another call is a "very high-pitched 'pseee'."

Sword-billed Hummingbird
Ensifera ensifera

Adults are 13–14 centimetres (5.1–5.5 in) long excluding the bill and weigh 10–15 g (0.35–0.53 oz), with males being slightly larger on average than females. The most distinctive feature of the species is the enormous bill, which is 8–12 centimetres (3.1–4.7 in) long. The bill is the largest of any hummingbird and the largest with respect to body length for any bird. The sword-billed hummingbird displays sexual dimorphism. Males have shorter bills but longer wings and tails than females. Voice: The sword-billed hummingbird makes a low, guttural, slightly trilled trrr.
