Black-backed Dwarf Kingfisher
Oriental Dwarf Kingfisher (Ceyx erithaca)
"Colorful! Small!"
Also known as Black-backed Dwarf-Kingfisher or Three-toed Kingfisher
Guys they're just a normal kingfisher who happens to be tiny and also very brightly colored. They're so cute!
This kingfisher is most commonly found in deciduous and evergreen primary and secondary forests across the Indian Subcontinent. They can also be found in alluvial (riverside) forests, rubber gardens, or dense aggregates of palms, bamboo, or other shrubs.
Nests are built into stream banks, road cuttings, or the soil near roots of a fallen tree. The pair will dig together into the soft dirt, carving out a horizontal tunnel which ends in an egg chamber. Both parents will take turns incubating, though the mother stays with the eggs overnight. It takes about 18 days to incubate, and then 18-20 days for the hatched chicks to fledge.
There was some confusing while I was looking for pictures of this bird, especially since e-bird notes that they're named "Black-backed dwarf-kingfisher" and not "Oriental", yet the picture I found did not show a bird with a black back. Apparently some genetic testing has been done, since there has been dispute about the two color morphs being the same species.
"C. erithaca comprises two principal colour morphs: the black morph (the black-backed kingfisher or oriental dwarf kingfisher), and the rufous morph, which is sometimes designated as a separate species, (rufous kingfisher), C. rufidorsa. A recent study has revealed genetic differences between C. erithaca and C. rufidorsa, suggesting that they are not morphs, but two distinct lineages."

Found in parts of South and Southeast Asia, these small kingfishers live near forest streams. They eat insects and other invertebrates, as well as some reptiles and amphibians, hunting from perches. Pairs dig burrows as long as three feet (one meter) into banks, laying their eggs in nest chambers at the ends of the tunnels. Both parents incubate the eggs and feed the chicks.
