The Sulawesi Bush Warbler, *Locustella castanea*, is a captivating and elusive songbird endemic to the montane forests of Sulawesi and its satellite islands. Measuring approximately 13-14 cm (5.1-5.5 inches) in length and weighing around 11-15 grams, this species is characterized by its rich chestnut-brown upperparts, contrasting with a greyish-white throat and belly that often has a rufous wash on the flanks.
