Distribution

Region

Sunda Islands (Indonesia)

Typical Environment

This species occupies upper montane forests, forest edges, and subalpine scrub on Indonesian islands, especially around the tree line. It frequents open patches with shrubs, grass tussocks, and scattered trees such as Casuarina. Birds often feed along trails, clearings, and on weedy slopes, moving between patches of seed-bearing plants. Outside the breeding season it can descend slightly to adjacent high-elevation secondary growth.

Useful to know

The Indonesian serin is a small finch of high montane habitats, often seen in lively, fast-moving flocks. It has historically been placed in Serinus but is now commonly treated in Chrysocorythus. Its bright, tinkling song carries over mossy forest edges and subalpine scrub. It is generally overlooked due to its remote, high-elevation range.

Behaviour

Temperament

social and active

Flight Pattern

short rapid wingbeats with undulating finch-like flight

Social Behavior

Often seen in small, loose flocks outside the breeding season, moving quickly between seed sources. Pairs nest in dense montane shrubs or small trees, building a neat cup. Both parents are believed to feed the young, and family groups may linger together after fledging.

Song Description

A bright, thin, tinkling series of trills and twitters, reminiscent of siskins. Calls are high-pitched chips and rapid twittering contact notes used to keep flocks together.

Inland dotterel

The inland dotterel is an endemic bird of the arid Australian interior. It forms loose flocks in sparsely vegetated gibber plain and claypans in the day where it loafs in the shade and eats shoots of shrubs. It is most often encountered at night when it forages on roads for insects. The relative remoteness of its habitat means that it is not well studied. The most detailed observations of the species were made by the South African arid-zone ornithology specialist Gordon Maclean in the 1970s. Alternate English names include Australian plover, inland plover, desert plover and prairie plover.

Inland thornbill

The inland thornbill was originally described by English ornithologist John Gould in The Birds of Australia. Inland thornbills are within the order passerines. The inland thornbill belongs to the genus Acanthiza, which now has three more species than the eleven outlined by Gould in The Birds of Australia. The Noongar people of southwestern Western Australia call A. apicalis "Djoobi-Djoolbang". The inland thornbill is also known as the broad-tail thornbill and presently contains several subspecies that were once considered independent species. The word apicalis comes from the Latin for 'tipped'.

Inti tanager

The Inti tanager, also known as the San Pedro tanager, is a species of bird in the family Thraupidae. It is the only member of the genus Heliothraupis. It is restricted to the lower Yungas of western Bolivia and southern Peru. Despite its striking coloration, call, and evolutionary distinctiveness, it was only described in 2021, and the bird's discovery and documentation to Western science only occurred during the prior two decades. On January 31, 2022, the South American Classification Committee of the American Ornithological Society (SACC) announced its formal addition to their South American species list.

Invisible rail

The invisible rail, Wallace's rail, or drummer rail is a large flightless rail that is endemic to the island of Halmahera in Northern Maluku, Indonesia, where it inhabits impenetrable sago swamps adjacent to forests. Its plumage is predominantly dark slate-grey, and the bare skin around its eyes, the long, thick bill, and the legs are all bright red. Its call is a low drumming sound which is accompanied by wing-beating. The difficulty of seeing this shy bird in its dense habitat means that information on its behaviour is limited.
