Saw-billed Hermit
Ramphodon naevius
The saw-billed hermit is 14 to 16 cm (5.5 to 6.3 in) long and weighs 5.3 to 9 g (0.19 to 0.32 oz). It is one of the three heaviest hermits and the male is heavier than the female. Both sexes have saw-like serrations on the mandible and the male's bill has a hooked tip as well. (The unrelated tooth-billed hummingbird (Androdon aequatorialis) is the only other hummingbird that has a serrated bill.) Both sexes have scaly brown upperparts and dark and pale striped underparts. They have a reddish ochre throat, a dark patch through the eye, and a white supercilium. Voice: The saw-billed hermit's song is a "very high, chattering twitter". Calls include "a sustained, rapid series of very high 'bic' notes" and "a descending series...of 'seee' notes." The calls are apparently used while defending the trap-line.

White-chinned Sapphire
Chlorestes cyanus
The white-chinned Sapphire is a small hummingbird measuring 8–9 centimetres (3.1–3.5 in) in length and weighing approximately 2.8–3.5 grams (0.099–0.123 oz).The species exhibits marked sexual dimorphism. Adult males are readily identified by their bright coral-red bill with a dark tip, brilliant violet-blue head and throat, and small white chin patch, which may not always be conspicuous. The upper parts are golden green, becoming more copper toward the rump. The upper tail-coverts range from deep copper to purple tones. and the tail is steel blue to blue black.
