Red-naped Trogon
Harpactes kasumba
Incandescently beautiful but sluggish and surprisingly hard to detect, this is a species of moist lowland and foothill forest. Male has a black head, bright red nape and underparts, brownish-orange back, and black-and-white-barred wings. Female is brownish with a yellow breast and belly. Both sexes have bright blue eye-rings and bills. Gives a series of gulpy squeaks: “kyew, kyew, kyew, kyew”.

分布与栖息地
The red-naped trogon is presumed to be a permanent resident or sedentary bird. Sedentary is “commonly used in the special sense of ‘non-migratory,’” and resident is defined as “remaining throughout the year in the area under reference”. At least 4,000 species of bird are regular migrants, which is approximately 40 percentage of the world's population of birds, however the red-napped trogon is not one of these. It does not migrate, but instead remains in the same location all year round.Red-naped trogons are confined to the Sundaic regions lowlands, also known as Sundaland, with a distribution size of 989,000 km2. The Sundaic lowlands is a biogeographical region of South-eastern Asia which encompasses the Sunda shelf, Malay Peninsula of the Asian mainland, and the large islands of Borneo, Java and Sumatra, including their surrounding islands. The eastern boundary of the Sundaic region is the Wallace Line which separates the Indomalaya and Australasia ecotones. <p>The global population size has not been quantified, but the species is described as rare in Thailand, fairly common in Peninsular Malaysia and Sumatra, rather scarce in Sarawak and uncommon in Singapore, Indonesia, Sarawak, Sabah and Brunei. The current population trend shows a decline in the number of red-naped trogons at a moderately rapid rate, owing to habitat loss and degradation throughout its distribution range.

Dja River Swamp Warbler
Bradypterus grandis
A large gray-brown warbler with a long and graduated tail, a white throat, and a heavily streaked upper breast. A highly localized resident in wetlands and swamps with tall sedge, typically within the forest zone; also occurs in adjacent tall grass and forest edge. Secretive and furtive, often creeping around close to the ground within its preferred habitat, but it will also sit up to defend its territory. Sings a strident and distinctive song with 3–4 downslurred “seet” introductory notes that accelerate into a throaty trill. Little Rush Warbler is smaller than Dja River Swamp Warbler and has a different song.
Pied Monarch
Arses kaupi
Small black-and-white flycatcher found in wetter forests of northern Queensland. White underparts except for black breast band, with black mask, tail, and wings, blue eyering, and back back with white band. Rear of head has large puffy white collar (like a space helmet). Compare Frill-necked Monarch, which lacks black breast band and has more black under chin. Forages treecreeper-style, moving up and down tree trunks looking for insects in the bark. Calls include a fast repeated whistle.
Ash-throated Casiornis
Casiornis fuscus
Large rufous flycatcher with a slight crest, a cinnamon back, dusky flight feathers, and buff underparts. Inhabits wooded caatinga (dry scrubby forest) in the breeding season, with migrants also found in Cerrado and Amazonian savannas and light woodland in the non-breeding season. The similar Rufous Casiornis has a rufous back, the same color as the wings.
