Justification of Red List category
Cyornis caerulatus is listed as Vulnerable under A2cd+3cd+4cd. The extensive clearing and degradation of lowland forests on Borneo and Sumatra has resulted in declines in suitable habitat of c. 20% over the past ten years. However, the extreme rarity of the species suggests rapid declines from threats that are not completely understood. It is suspected that the trade of the species has had, and will continue to have, a profound impact on the population. These impacts are inferred from the popularity of the genus in trade, and the rapid declines of the closely related C. banyumas. Consequentially, declines in the range of 20-40% are suspected.
