The cerulean kingfisher (Alcedo coerulescens) is a kingfisher in the subfamily Alcedininae which is native to parts of Indonesia. With an overall metallic blue impression, it is very similar to the common kingfisher, but it is white underneath instead of orange. Males average bluer than females, which have a greenish cast. The cerulean kingfisher is native to Sumatra, Java, the Kangean Islands, Bali, Lombok and Sumbawa, all in Indonesia. It is a resident species that inhabits low-lying areas near streams, canals, flooded paddy-fields and tidal estuaries.
