The collared kingfisher (Todiramphus chloris) is a medium-sized kingfisher belonging to the subfamily Halcyoninae, the tree kingfishers. It is also known as the white-collared kingfisher, black-masked kingfisher or mangrove kingfisher. It has a wide range extending from the Red Sea across southern Asia to Melanesia. A number of subspecies and subspecies groups have been split from this species including the Pacific kingfisher, the Islet kingfisher, the Torresian kingfisher, the Mariana kingfisher, and the Melanesian kingfisher.
It is most commonly found in coastal areas, particularly in mangrove swamps. It also inhabits farmland, open woodland, grassland and gardens. In some parts of its range, especially on islands, it can be seen further inland, ranging into forest or into mountain areas. Birds often perch conspicuously on wires, rocks or bare branches.
