Geomalia
species of bird
The geomalia or Sulawesi mountain thrush (Zoothera heinrichi) is a rare member of the thrush family endemic to Sulawesi in Indonesia. It is sometimes classified as Geomalia heinrichi, in which case it is monotypic in the genus Geomalia (which is the source of its primary common name).
The coloration of the bird is primarily dark brown with chestnut color on the breast. The long legs, long tail and short wings struck the discoverer as reminiscent of laughingthrushes, and the name Geomalia is itself a reference to another, superficially similar Sulawesi endemic, the malia, but the two species are not related. The specific name commemorates its discoverer, the German explorer Gerd Heinrich.
There has been some debate over the taxonomic affinities of the geomalia. While it has some features typical of thrushes (such as an upright posture, juveniles with spotted underparts, and thrush-like terrestrial foraging behavior), several others (such as its long, rounded tail; short wings; and apparent lack of a song) have led authors to question whether its placement in the thrush family is appropriate. A genetic study published in 2013 confirmed its placement in the family Turdidae, specifically as an aberrant member of the genus Zoothera.
Due to its isolation and the difficulty of getting to its habitat, the geomalia is little-studied. The species may be threatened by uncontrolled logging and other activities that cause degradation of the Sulawesi highlands, including the grounds of legally protected lands such as Lore Lindu National Park.
This brief starts where responsible research should: with the source description of “Geomalia” as species of bird. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of bird. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Dec 21, 2025. The linked authority identifier is Q20745683. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2013.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
