Chestnut-necklaced Partridge
Tropicoperdix charltonii
A shy partridge of tropical lowland rainforest. Brown with buff speckled upperparts, dark barring on the chest and sides, orange-brown belly, rusty bib, black speckled collar, and white, finely speckled throat. Uncommon and declining throughout its range. Forages in small flocks on the forest floor. Found at lower altitudes than other partridges in range and distinguished by its yellow legs and pale orange ear patch. Song, often given as a duet, consists of loud, tremulous whistles.

The whitish supercilium, throat and neck have brown streaks. The upper breast is chestnut, with a blackish collar above it. The lower breast is brown, and the belly and flanks are buff. There are dark scales on the lower breast and flanks. The upperparts are brown, finely marked blackish and buff. The beak is greenish yellow, and the legs are yellow. The female bird is smaller and a little duller than the male. The subspecies atjenensis has brighter plumage, and graydoni has greenish-yellow legs.
分类信息
This species was described by Thomas Campbell Eyton as Perdix Charltonii in 1845. The IOC World Bird List recognises the subspecies T. c. charltonii found in the Malay Peninsula, T. c. atjenensis in Sumatra. Some authorities have considered the green-legged partridge (A. chloropus) to be conspecific with this species. The Sabah partridge (T. graydoni) was also previously considered conspecific.

Yellow-throated Apalis
Apalis flavigularis
A slender, long-tailed mid-story and canopy warbler-like bird with olive green upperparts extending to the flanks, a grayish face (sometimes extending to the forehead) with a striking pale lemon eye, and a bright yellow throat and breast bisected by a thin black bar. Pairs are resident in forest, forest edge, and plantations, where they may join mixed-species flocks. Song, often in duet, a strident repeated two syllable “ti-leep” from the male and a higher-pitched ‘ti-ti-ti….” from the female.
Junin Antpitta
Grallaria obscura
Medium-sized, plain antpitta found in a limited area of the eastern Andes in south central Peru. It is uniform brown lacking strong field marks, but the pale eyering helps separate it from the similar Oxapampa Antpitta. Range and voice are also very important for ID. Typical songs include a short “bit-burr” and a series of five or six grating whistles. Inhabits the understory of high elevation forest and is mostly terrestrial, but sometimes perches higher to sing. It was formerly considered a subspecies of what used to be called Rufous Antpitta.
Black Coucal
Centropus grillii
Small coucal of marshes, swamps, and wet grassland. Distinctive in breeding plumage: black with a rufous wing. In non-breeding plumage, buffy and streaked. Skulks in the undergrowth, occasionally emerging to sit on an exposed perch. Vocalizations are a two part “kuu-kuk” and a descending and accelerating series of “tow” notes. In non-breeding plumage, separated from White-browed and immature Senegal coucals by its slightly smaller size and lack of a white eye stripe.
