Blyth's Leaf Warbler
Phylloscopus reguloides
Fairly bright mid-sized leaf-warbler, yellowish-green above and white below with two wingbars, a broad yellow-suffused eyebrow, and a pale stripe across a gray crown. Amount of white in the tail is intermediate between White-tailed Leaf-Warbler and Emei Leaf-Warbler. A brighter crown stripe separates Blyth’s from the Emei, and unique behavior serves to distinguish this species from White-tailed: Blyth’s constantly flicks wings one after the other, while White-tailed flicks them simultaneously. Kloss’s Leaf-Warbler is much brighter overall, especially on the head and vent. Hartert’s and Claudia’s Leaf-Warblers are closely related, physically similar, and may pose issues in areas of overlap: look out for a more yellowish breast on Hartert’s and a whiter eyebrow and less white in the tail in Claudia’s. Blyth’s song is a high “tsi-tsslehlee-tsslehlee” or “tsi-tchew-witty-tchew-witty-tchew,” with the introductory note separating it from Hartert’s but not always Claudia’s. Breeds in broadleaf (often oak), coniferous, or mixed forests at middle to high elevations, and descends into lower foothill regions in the winter.
Identification
Blyth's leaf warbler (Phylloscopus reguloides) is a species of leaf warbler (family Phylloscopidae). It was formerly included in the "Old World warbler" assemblage. It is found mainly in Southeast Asia, southern China and along the Himalayas till northern Pakistan. Its natural habitat is subtropical or tropical moist montane forests. This bird was named after the English zoologist Edward Blyth. In regard to its birdsong complexity, which takes into account the number of distinct notes, Blyth leaf warbler's high complexity is a consequence of increased variation between song types.

Bartlett's Tinamou
Crypturellus bartletti
Small tinamou of floodplain rainforest. Reddish brown with limited black barring on the wings. Found in tall lowland rainforest, especially around water and in seasonally flooded areas, and can be quite common. Listen for a series of whistles given at a pace of about one note per four seconds that gradually accelerates until about twice as fast; recalls the song of Cinereous Tinamou, but faster and usually accelerating.
Long-tailed Tit
Aegithalos caudatus
Adorable, active little bird with a minute stubby bill. Distinctive: tiny and fluffy with attractive pinkish, black, and white plumage and very long tail. Some plumage variation across range; adults in northern parts of range have white head without broad black eyebrows and whiter underparts, while those further south are darker. Juveniles (seen in summer–early autumn) have brown head sides; become like adult by winter. Often travels in groups, at times joining with flocks of other tits and small woodland birds. High-pitched, fussy calls add to restless demeanor. Inhabits wooded and forested habitats, parks, gardens, and hedges in farmland; sometimes visits bird feeders.
Spangled Honeyeater
Melipotes ater
A large, common, honeyeater of montane forests on the Huon Peninsular. Blackish with a paler throat and long tail. Chest and belly covered in white spots in a half-moon shape. Large irregular-shaped, bare, yellow facial skin that can flush to red. Somewhat sociable, being found in small to large groups. Huon Melidectes is a similar size but has a very different face. Calls, squeals and parrotlike squawks.
