Population justification: The population is estimated to number 34-150 individuals (Fauzan and Bashari 2016), roughly equating to 21-100 mature individuals. This total is similar to those reported from 2001 (19 to 135 birds [Riley and Wardill 2001]); 2003, 2005 and 2006 (<215 birds [BirdLife Indonesia 2007); and 2009 (30-106 [Burung Indonesia 2009]). Each survey has visited a greater number of potential sites and added new locations, but has not managed to increase the total estimate.

Trend justification: Within the Sahendaruman crater, small-scale habitat loss continues in some valleys inhabited by the species (Martin 2018). Small-scale clearance (plots of c.0.3 ha that may or may not have been previously cleared) was recorded in most valleys surveyed below or adjacent to territories of the Cerulean Paradise-flycatcher (Martin 2018). At two valleys near Malamenggu village, clearance and selective logging occurred between surveys in November 2014 and in May 2015 (Martin 2018). In these valleys, three individuals were present during the first survey (Fauzan and Bashari 2016), but none were found in 2015 (Martin 2018). Consequently, the species is believed to be suffering from a continuing decline, certainly in the area of suitable habitat and likely also in numbers of mature individuals.
