The spotted crocias is a passerine bird in the family Leiothrichidae. It is endemic to the island of Java in Indonesia, where it is confined to west Java.
Region
West Java montane forests
Typical Environment
Confined to the montane evergreen and mossy forests of western Java, Indonesia. It favors dense, humid interior forest with abundant epiphytes and bamboo thickets. Birds are most often encountered along forested ridges, ravines, and mature secondary growth, rarely descending to lowlands. It can occur at forest edges but is most frequent in intact canopy and subcanopy layers.
Altitude Range
900–2000 m

The spotted crocias is one of only two crocias species, the other being the grey-crowned crocias of Vietnam. It keeps to mossy, shaded montane forest and often joins mixed-species flocks while foraging. Its tiny range in West Java makes it vulnerable to habitat loss, and protected areas like Gunung Halimun–Salak National Park are important strongholds.
Temperament
skulking and wary
Flight Pattern
short rapid wingbeats
Social Behavior
Usually seen in pairs or small family groups, often joining mixed-species flocks with other montane insectivores. Nests are placed in dense vegetation, with both parents participating in care. Territorial during breeding but otherwise relatively tolerant of nearby conspecifics.
Migratory Pattern
Resident
Song Description
A series of clear, mellow whistles interspersed with soft trills and chatters. Calls include thin tseep notes used to maintain contact within flocks.
