 Previously known only from a single specimen collected in 1873, this rare bird was rediscovered in October 1998 around forested valleys of Mount Sahendaruman in southern Sangihe.Its diet consists mainly of insects and other small invertebrates.Due to ongoing habitat loss, a small population size, and limited range, the cerulean paradise flycatcher is evaluated as Critically Endangered on the IUCN Red List of Threatened Species.
