Description
Blyth's kingfisher is between 22 and 23 centimetres (8 ⁄8 and 9 in) in length, making it the largest of the Alcedo kingfishers. The wing of the male is between 9.6 and 10.2 centimetres (3 ⁄4 and 4 in) long, and that of the female between 9.5 and 10.3 centimetres (3 ⁄4 and 4 in). On the male, the feathering on the head is black, with shiny tips of bright blue. It has a neck patch that is whitish or buff in colour, as is the chin. The breast and belly are rufous, except for a dark blackish-blue patch on the breast. The legs and feet of the bird are also red. The bill is entirely black in the male, while the female has a red base to the mandible. The iris of the bird is reddish brown. The lores of the bird are black, and have a buff coloured streak above them. The back of the bird from mantle to the tail coverts is a bright cobalt blue or azure, with a tinge of purple towards the rump and the tail coverts. When the bird is at rest, the upper parts may appear brownish black. The tail itself is a darker ultramarine blue. The wings and the scapular feathers are a dark greenish black. The feathers of the upperwing coverts have cobalt-blue tips, while the underwing coverts are dark rufous-red. The lesser and median coverts have prominent speckles of cobalt. Any distinctive features in the plumage of the juvenile are not known. The species is morphologically similar to the blue-eared kingfisher (Alcedo meninting), but in comparison is substantially larger. Its bill is heavier and longer than that of the blue-eared kingfisher, and is entirely black. Its crown and wings are less brilliant as those of the smaller bird, and it may be distinguished by the speckles of light blue on its crown and wing coverts. The dark ear coverts set it apart from the common kingfisher (Alcedo atthis), which has rufous ear-coverts. It is similar to the female blue-banded kingfisher (Alcedo euryzona), but the two species do not overlap in their range. The call of the species is described as a loud "pseet", less shrill but louder and more hoarse than that of the common kingfisher, and similar but louder to that of the blue-eared kingfisher. One of the calls made by the slaty-backed forktail (Enicurus schistaceus) is sometimes mistaken for the call of Blyth's kingfisher.

Feeding Habits
Blyth's Kingfisher primarily feeds on fish, with insects also included in its diet. It hunts from low, hidden perches above water, diving to catch its prey, and frequently reuses these spots.
Habitat
The blyth's Kingfisher typically inhabits streams and small rivers situated within deep ravines and hilly terrains, surrounded by evergreen forests. This species is also found alongside forest streams that adjoin well-wooded farmlands, predominantly inhabiting areas that foster a rich, perennially green canopy.
Dite type
Piscivorous

Behavior
The breeding period of Blyth's kingfisher is chiefly between April and May, extending to March and June. The nests are built at the end of a tunnel in a muddy bank, next to either a stream or a ravine in the forest. The tunnel extends straight, then rises, before descending to the chamber in which the nest is. This chamber is between 15 and 20 centimetres (6 and 8 in) wide and 10 and 13 centimetres (4 and 5 in) high. The width of the tunnel is typically 8 centimetres (3 ⁄8 in): the length varies with the soil, ranging from 45 to 60 centimetres (17 ⁄2 to 23 ⁄2 in) in hard soil to 2 metres (6 ft 7 in) in sandy soil. Between four and six eggs are laid, incubated by both parents. The parents sit very tight; nests become covered in faecal matter. The periods of incubation and fledging are not known. The species feeds on fish and insects it catches by diving in water bodies. Unlike other Alcedo kingfishers, Blyth's kingfisher dives from a shrub close above the water, rather than from an exposed vantage point. The species is presumed not to migrate. It is described as a shy bird.
Distribution Area
Blyth's kingfisher frequents small rivers and waterways in evergreen forest, hilly regions, or deep ravines. It is sometimes found near streams near well-wooded farmland. Its elevational range is chiefly between 400 and 1,000 metres (1,300 and 3,300 ft) above sea level, extending to a minimum of 200 metres (660 ft) and a maximum of 1,200 metres (3,900 ft). The density of the species is low across its range. In China, it is known to be found in the Mengyang Nature Reserve in Yunnan, and in the Nonggang National Nature Reserve and Diding Nature Reserve in Guangxi province. It is also known to be present in Hainan. In Vietnam the species is found in Annam and western Tonkin, in which regions it is fairly common. In northern Laos and the Annamite mountains, it may be locally common. It is also found in Myanmar, where its density varies considerably, and is either a visitor or a rare resident in northwestern Thailand. It is rare in Bhutan in northeastern India, and a vagrant in Bangladesh and eastern Nepal. Its range in northeast India includes the eastern Himalayas, up to 1,200 metres (3,900 ft).
Species Status
The population of Blyth's kingfisher has not been quantified globally. In China, the species is estimated to have fewer than 100 breeding pairs. The species occurs at a low density even within a favorable habitat. The habitats it favors are being degraded and fragmented by human activity. Other potential threats to the species include water pollution in the rivers it inhabits and anthropogenic disturbance such as deforestation. No specific conservation actions are known to have been taken to protect the species. Due to the presence of human disturbance, its population is thought to be in slow decline. The International Union for Conservation of Nature categorizes the species as "near threatened"; it has previously classified the species as "vulnerable."
