Ruiseñor de Formosa

<em>Tarsiger johnstoniae</em>, the Collared Bush Robin, is a small passerine bird in the family Muscicapidae. This species is assessed as Least Concern on the IUCN Red List. It is documented in Taiwan, where it is endemic and inhabits montane forests, particularly in dense undergrowth at higher elevations. Members of the genus <em>Tarsiger</em> are typically shy, ground-foraging birds that feed on insects and other small invertebrates. The Collared Bush Robin is named for the distinctive collar pattern in the male's plumage, which contrasts with the brownish coloration of the female. Diet, population estimates, population trend, and biological measurements such as average length, weight, and lifespan are not specified in the available records. Biological traits of this species remain poorly documented in the scientific literature. Its Least Concern designation indicates that the population is not currently at elevated extinction risk, though as a Taiwanese endemic restricted to montane forest, it may be sensitive to climate-induced shifts in its habitat.
