Indonesian Serin
Chrysocorythus estherae
Rare and localized highland finch, restricted to upper montane forest and open scrubby and grassy habitats above the treeline. Generally not very obvious, often foraging quietly in dense growth, but flocks will sometimes betray their presence by flying overhead and giving a chorus of chittering twitter calls. Found only on high peaks in Sumatra, Java, and Sulawesi. Combination of thick conical bill, bright yellow wing-bars, and well-streaked underparts are unique within this species’ range and habitat. A currently undescribed population in north-central Sulawesi has reddish-orange in place of other populations’ yellow patches. Song is a dry, whirring buzz following a few husky notes.

The Indonesian serin (Chrysocorythus estherae) is a species of finch in the family Fringillidae. It is found in Indonesia. Its natural habitats are subtropical or tropical moist montane forest and subtropical or tropical high-altitude grassland. The Indonesian serin was formerly placed in the genus Serinus but a phylogenetic analysis of mitochondrial DNA sequences found that the species was not closely related to other member of Serinus nor to the geographically nearest finch, the Vietnamese greenfinch but to the European Goldfinch Carduelis carduelis and to the Citril Finch Carduelis citrinella. The species was therefore assigned to a separate genus Chrysocorythus, a name that had previously been proposed by the German ornithologist Hans Edmund Wolters in 1967. The Mindanao serin (C. mindanensis) of Mindanao was formerly considered conspecific, together called the mountain serin, but was split as a distinct species by the IOC in 2021. The Indonesian serin is polytypic with four subspecies, including the nominate subspecies of western Java. The other races include: Chrysocorythus estherae vanderbilti (Meyer de Schauensee, 1939) (including Serinus estherae ripleyi Chasen, 1939). Sumatra. Chrysocorythus estherae orientalis (Chasen, 1940) (including the replacement name Serinus estherae chaseni). Tengger range, eastern Java. Chrysocorythus estherae renatae (Schuchmann & Wolters, 1982). Mount Rantekombola, Sulawesi. There are also outstanding records of an unusual taxon of this species in Lore Lindu National Park, northern Central Sulawesi.

Northern Pied-Babbler
Turdoides hypoleuca
A boldly marked babbler with gray-brown upperparts and mostly white underparts. Also note the pale eye and variable gray-brown blotching on the sides and on the breast. Found in woodland, thickets, and lush scrub, almost always in small groups which forage by hopping across the ground. Similar in shape and size to other babblers, but easily separated by the strikingly light-and-dark plumage. Nasal babbling call is frequently given, usually by a whole group in chorus.
Boulder Chat
Pinarornis plumosus
Large, unique, sooty-colored chat with a proportionately small head and long broad white-tipped tail (except on central feathers), often seen only on spread tail. White spots in wings are obvious only in flight. Immature is paler. Pairs and family groups prefer rocky granite hills and outcrops that have light tree cover, especially embedded within Mopane and Miombo woodland. Mobile, they scuttle and bound over rocks and perch in trees, tail regularly raised or fanned. Gives a loud varied collection of high-pitched whistles and trills, often likened to a squeaky wheel.
Black-headed Trogon
Trogon melanocephalus
Handsome, medium-size, yellow-bellied trogon of tropical lowlands. Occurs in forest, but also in hedgerows, semi-open areas with taller trees, mangroves; not as tied to forest as is smaller Gartered Trogon. Perches at mid-upper levels, at times with several birds in a small area. Both male and female have a complete blue-gray eye-ring, and the underside of the tail is marked with big blocks of white. Digs its nests in arboreal termite nests.
