Straight-billed Hermit
Phaethornis bourcieri
Large, drab grayish hermit with a long straight bill. Lacks a strong face pattern. Also note elongated white central tail feathers. Occurs in lowlands across much of northern South America, typically below 700 m. Found within terra firme forest, staying low and quickly zipping around flower patches in the understory.
Identification
The straight-billed hermit is 12 to 14 cm (4.7 to 5.5 in) long and weighs 3.5 to 5 g (0.12 to 0.18 oz). It is one of the few hermit hummingbirds with a straight bill. Its upperparts are olive green and the underparts brownish to grayish. The innermost pair of tail feathers are longer than the others and have long white tips; the others also have white tips. P. b. major is significantly larger than the nominate but has similar plumage.
Taxonomy
The straight-billed hermit and needle-billed hermit (P. philippii) were at one time placed in genus Ametrornis that was later merged into Phaethornis. The South American Classification Committee (SACC) of the American Ornithological Society, the International Ornithological Committee (IOC), and the Clements taxonomy recognize two subspecies, the nominate P. b. bourcieri and P. b. major. However, BirdLife International's Handbook of the Birds of the World (HBW) follows a 2017 publication and treats P. b. major as a separate species, the ash-bellied hermit. A third subspecies, P. b. whitelyi, has been proposed but its characteristics are within the variation seen in the rest of the nominate.

Range and habitat
The nominate subspecies of straight-billed hermit is found from southeastern Colombia south through eastern Ecuador into northeastern Peru and east through southern Venezuela and the Guianas into Brazil as far south as both banks of the Amazon River. P. b. major is found only in east-central Brazil south of the Amazon River and east of the lower Tapajós River. The species mostly inhabits the understory of terra firme forest and adjacent semi-deciduous and foothill forests. It can occasionally be found in other landscapes such as várzea forest, bamboo thickets, plantations, and secondary forest. In elevation it ranges as high as 1,600 m (5,200 ft), in southern Venezuela.

Behavior
The straight-billed hermit is a "trap-line" feeder like other hermit hummingbirds, visiting a circuit of a variety of flowering plants for nectar. It also consumes small arthropods.<p>The straight-billed hermit's breeding seasons vary throughout its large range, from March to May in Brazil and July to November in Peru. It builds a long cone-shaped nest from plant fibers and spider silk suspended under the tip of a long drooping leaf. The clutch size is two eggs.<p>The straight-billed hermit's song is "a high-pitched phrase repeated over and over, punctuated by short dull-sounding notes, 'tsii’ti’ti’tsii...tip...tip...tsii’ti’ti’tsii....tip...tip...tip...'”, and is very different from the songs of other Phaethornis hermits. Its calls are usually given in flight and include "a rather monotonous 'tseet' and a dull 'chep'."

Akun Eagle-Owl
Ketupa leucosticta
A small insectivorous eagle-owl that sallies to catch flying insects from mid-canopy perches near openings in lowland forest. Has a distinctive pale belly with large dark spots, a brownish-gray face and back, yellow eyes, and a banded tail. Vocalizations include soft grunts, a short ascending or descending whistled “woooh,” and short trilled calls. Vocalizations can resemble those of other eagle-owls within its range, but Akun Eagle-Owl’s distinctive pale belly and large, obvious spotting on a mostly white chest are unique.
Black-girdled Barbet
Capito dayi
Stocky bird with a stout bill. Plumage is largely black and white, but the male has a red cap, and both sexes have a red vent. Canopy dweller in humid forests, including the forest edge; often seen at fruiting trees. Accompanies mixed-species flocks. Sings a series of low, hollow “hooo” notes that accelerates towards the end, similar to the songs of some antthrushes.
Long-eared Owl
Asio otus
Medium-sized, rather slender owl with long "ear" tufts. Extensive range across Northern Hemisphere. North American birds are rather dark and coarsely marked, with pumpkin-colored face patches and yellow eyes. Eurasian populations are paler overall, especially on the face, and have reddish eyes. Strictly nocturnal; rarely seen foraging at dusk and dawn. Found in areas with a mix of dense cover for roosting, such as brushy thickets or conifer groves, and open spaces for hunting. Generally uncommon to rare and seldom-seen, but can gather in communal winter roosts with dozens of individuals (if you're lucky enough to find a roost, do not disturb the birds). Compare with Short-eared Owl. Typical vocalization is a single low “woop” repeated every few seconds; also gives a wide range of maniacal catlike screeches and doglike barks.
