Both sexes of nominate race have olive-brown head, whitish chin, buff neck and underparts; upperparts dark green-blue, wings and tail bluer, rump azure; bill scarlet, darker at tip; iris dark brown; legs and feet orange-red.

Habitat: It is found in lowland waterside habitats such as the forested edges of streams, canals, large rivers, reservoirs, lakes and seashores. It is also found in primary rainforest, swamp-forest, bamboo-forest and mangroves, but also in more open areas such as coconut plantations and paddy fields; often seen perched on mangrove roots on seashore. It is found from Seashore up to 870 m.
Food Habits: It eats marine and freshwater fish, crabs and other crustaceans, but also takes frogs, lizards, rodents, young birds, also insects and insect larvae. It perches quietly on stilt roots in mangroves or on branch overhanging water, above the water, watching for prey and occasionally bobbing head or wagging tail; sits vertically, with bill inclined at 40° below horizontal; plunges down at steep angle into water or on to land to capture prey, which is then taken back to the perch and banged against branch a few times to immobilize it, before being swallowed. It follows foraging smooth-coated otters and catching prey items disturbed by them.
Breeding Habits: They breed in Jan-Sept in India. The nest is excavated in a riverbank, or decayed tree trunk, or ground or arboreal termitarium. Both sexes dig nest-tunnel that is 9–10 cm wide, up to 1 m long, ending in nest-chamber 23 cm in diameter and 13 cm high .They lay a clutch 2-5 eggs. The female parent incubates. The fledging period is 40 days. Both sexes feed the young.
