Dusky Tetraka
Crossleyia tenebrosa
Extremely rare and enigmatic tetraka. Dark olive-green overall, with a pale yellowish throat and ring around the eye. Chunky and short-tailed. Madagascar endemic that is known from a handful of sites in the northeastern rainforest at middle and low elevations. Inhabits the ground and understory and acts much like Yellow-browed Oxylabes, but lacks that species’ bold eyebrow. Shorter-tailed than Spectacled Tetraka, with a duller eye-ring. Call is a very high, thin “seet” given singly or in a quick series.

White-lored Tyrannulet
Ornithion inerme
Small flycatcher of rainforest canopy. Olive with bright white or buffy wing bars and a gray head. Black eye line with white extending from the base of the bill to above and behind the eye. Bold wing bars help distinguish it from similar flycatchers; also, note darker olive plumage and clean facial pattern. Forages singly or in pairs in the canopy of mature rainforest, and, like many rainforest tyrannulets, can be quite inconspicuous. Listen for its voice, a slightly accelerating series of 4-5 high whistles: “pwee, pwee, pwee-pee.”
White-collared Yuhina
Parayuhina diademata
Small brown bird with a flashy white patch on the back of an erect crest. Inhabits broadleaved forests and adjacent second growth, parks, and gardens in hilly and montane regions. Often travels in flocks, sometimes associating with other species. Usually forages at middle levels in the forest. Gives dry trills and buzzy whistles.
Plain-winged Antwren
Myrmotherula behni
Small, rare antbird found in lush cloud forest along the east slope of the Andes and in the tepui region of Venezuela, Guyana, and extreme northern Brazil. Male is dark gray with black throat and breast; extent of black is geographically variable. Female is brown with a pale throat. Similar to Slaty Antwren but lacks wing markings. Inhabits forest understory, where often encountered with mixed-species flocks. Song is a series of four to ten soft whistles.
