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.

Useful to know

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.
