Kloss's Leaf Warbler
Phylloscopus ogilviegranti
Unlike “Blyth’s-type” leaf warblers, the similarly-sized but somewhat stouter Kloss’s and Davison’s leaf warblers flick both of their wings at the same time. A brightly-marked leaf warbler with a yolk-yellow brow and crown stripe, and a pale-yellow vent which contrasts with the white breast and belly. Wing bars are also yellow and average stronger than those of Claudia’s, Blyth’s, and Hartert’s warblers. Yellow vent and strong crown stripe may cause confusion with Eastern Crowned Warbler when the latter is migrating, but look for the relatively small, stubby bill and the strong double wing bars of Kloss’s.
Identification
Kloss's leaf warbler (Phylloscopus ogilviegranti) is a leaf warbler found in Cambodia, China, Laos, Thailand, and Vietnam. Its natural habitats are temperate forests, subtropical or tropical moist lowland forests, and subtropical or tropical moist montane forests. Kloss's leaf warbler was formerly considered as a subspecies of Davison's leaf warbler. It was promoted to species status based on evidence from both molecular genetic and vocalization studies.

South African Shelduck
Tadorna cana
A mostly rusty-colored waterfowl. Male has a gray neck and head; female similar with a whitish face. Resident and nomadic throughout its range, preferring estuaries, rivers, and impoundments within arid zones. Gives a honk call. Egyptian Goose is similar, but larger, with a brown blotch in the middle of the chest and a different head pattern that includes a tawny eye surrounded by an expanded rusty eye-ring. Egyptian Goose honk is higher and harsher than this species.
White-bellied Erpornis
Erpornis zantholeuca
Small, crested, yuhina-like bird, frequently seen as a part of mixed flocks in a wide range of forested habitats. Upperparts yellowish green, underparts dingy gray except for yellow undertail coverts and whitish throat. Forages mostly in the upper layers of vegetation, from which its loud “nay nay” call is often heard.
Olive-green Tanager
Orthogonys chloricterus
Large tanager found in the canopy of montane forests and at forest borders in coastal mountain ranges. Highly gregarious; gathers in groups of up to 20 individuals and often visits feeders. Rather nondescript, olive-green above and yellowish below with a dark bill and eyes. The song is a very short and loud “sreee.”
