Little Shrikethrush (Tagula)
Colluricincla megarhyncha discolor
A chunky bird with a notably thick dark bill. Fairly nondescript: olive-brown on the upperparts and paler below. Found at low and middle elevations, in the understory and at middle levels of humid forest. Rich, melodious, variable song consists of whistles and rasping notes, often in an up-and-down pattern. Within its limited range, most likely to be confused with female Louisiade Whistler, but drabber overall, without yellow underparts.

Canary Flyrobin
Devioeca papuana
A small bird of montane forest interior. Olive-green upperparts, yellow underparts, black bill and orange legs. Sallies for insects in the midstory but can also hop around flicking wings and fanning its tail. Somewhat similar to Yellow-legged Flycatcher and White-faced Robin, but Papuan Flycatcher occurs at higher elevation and lacks any white on the face or throat. Voice, a high-pitch, jumbled song or a simple “chip”.
Fulvous-dotted Treerunner
Margarornis stellatus
A uniquely-marked little Furnariid. Very uncommon in restricted range on the west slope of the Andes in Colombia and Ecuador. Mostly bright orange-rufous with a dazzling white throat that bleeds down into bold speckles on upper breast. Singles or pairs forage with mixed-species flocks, usually hitching along mossy branches in the middle to upper levels. Occurs in humid mossy forest from around 1,200–2,200 m, typically at lower elevations than Pearled Treerunner.
Spotted Bamboowren
Psilorhamphus guttatus
Strange-looking small bird with a slender bill and a rather long tail. Found in bamboo stands in humid forests and second growth where it can be very hard to see. Males have a spotted gray head, back, and breast and a brown tail, rump, and belly, which is faintly barred. Females are similar but browner. The song can be delivered loudly or quietly and can be easily overlooked.
