Sangihe lilac kingfisher
The Sangihe lilac kingfisher (Cittura sanghirensis) is a species of kingfisher in the genus Cittura, endemic to the lowlands of the Indonesian island of Sangihe. It was previously considered a subspecies of the Sulawesi lilac kingfisher (C. cyanotis), but was split as a distinct species by the IUCN Red List and BirdLife International in 2014, and the International Ornithological Congress and Clements followed suit in 2022.
