Makira Dwarf Kingfisher

Overview

The Makira dwarf kingfisher (Ceyx gentianus) is a species of bird in the family Alcedinidae that is endemic to Makira Island. Its natural habitat is subtropical or tropical moist lowland forests.
This species was formerly considered one of the 15 recognised subspecies of what was then known as the variable dwarf kingfisher (Ceyx lepidus or Alcedo lepidus). A molecular phylogenetic study published in 2013 found that most of the insular subspecies had substantially diverged from one another.
