行为
The Napo sabrewing's movements, if any, are not known.<p>The Napo sabrewing forages for nectar from the understory to the mid-strata of the forest. In addition to nectar it feeds on small insects by hawking from a perch. No details of its diet are known.<p>Napo sabrewings have been noted in breeding condition in October and November, but nothing else is known about the species' breeding phenology.<p>The Napo sabrewing's song is "a long series of two notes repeated continuously at evenly spaced intervals 'tslip...tseek...tslip...tseek...' or 'trrip...tseek...trrip...tseek'." Its calls include "a single 'chip' or doubled 'chirrip'" that sometimes become a short rattle.

White-lined Antbird
Myrmoborus lophotes
Large antbird of bamboo stands in river edge forest. Males are dark gray with bright white wing bars and a darker blackish crest that is raised when agitated; females appear two-toned: orange above, with creamy white face and underparts. Both sexes have a red eye. Primarily found in bamboo, but occasionally found in other dense habitats, like cane thickets and heliconias along streams. Song is a descending, accelerating series of whistled notes, with a noticeable gap between the first note and the rest; “TEW … tew, tew, tew, tewtutututu”.
Reed Cormorant
Microcarbo africanus
A small, speckle-backed cormorant that is common and widespread in fresh water. The adult is blackish with a short black crest above the bill. Immatures are brownish with paler underparts. Although they share the same habitat with Great Cormorant, Long-tailed Cormorants can be separated by their much smaller size, red eyes, and proportionately longer tails. Generally, Long-tailed Cormorant avoids the marine habitats of the similar-looking Crowned Cormorant, which has a larger crest, an unspeckled back, and a shorter tail.
Melodious Warbler
Hippolais polyglotta
Medium-sized warbler, light olive-brown above and yellowish below with a rather long bill. Compared to Icterine Warbler, wings are shorter and lack the pale panel. Song is fast and prolonged, containing quite a lot of mimicry and usually some House Sparrow-like chattery calls intermixed. Breeds in southwest Europe and northern Morocco, in forests, scrubbier vegetation, orchards, and well-wooded gardens. Winters in various wooded habitats in tropical Africa, including wooded savanna.
