Asian Fairy-bluebird

Identification

The Asian fairy-bluebird is a medium-sized, arboreal passerine measuring 24 to 27 centimetres in length. The species exhibits striking sexual dimorphism. Males are unmistakable: they display glossy, iridescent ultramarine-blue upperparts with lilac reflections, contrasting sharply with deep black underparts, flight feathers, and head sides. Some wing coverts and middle tail-feathers are tipped or glossed with blue. Females and first-year males are considerably duller, appearing entirely in brownish-blue tones with darker brown flight feathers and tail. Both sexes have a distinctive crimson iris, pinkish eyelids, and black bill and legs. Notably, young males acquire adult plumage in March without undergoing a complete moult, with feathers gradually becoming fringed in bright blue.

Range & Habitat

This tropical species is distributed across a vast range spanning southern Asia, Indochina, and the Greater Sundas. Its range extends from Sri Lanka and the western coast of India through the Himalayas and northeastern regions including Assam, across Bangladesh and Burma, and throughout most of Indochina, Peninsular Malaysia, Sumatra, Borneo, and Java, including the Andaman and Nicobar Islands. In India, it is confined to evergreen forests of hills and plains, while elsewhere it inhabits humid and deciduous forests from lowlands up to approximately 1,600 metres elevation. The species shows a preference for mature rainforests and cardamom plantations under native shade trees, being less frequent in coffee plantations.

Behaviour & Diet

The Asian fairy-bluebird is common throughout most of its range, typically moving about in small parties or pairs. It is an arboreal bird, generally found in larger forest trees. The species feeds principally on fruit, supplemented by nectar and some insects. Its distinctive call is a liquid two-note sound rendered as "glue-it." Breeding occurs from February to April, when pairs construct shallow, cup-shaped nests made variously of moss or small twigs in saplings or small trees. Clutches typically consist of two greenish-white eggs marked with brown.

Best Time & Places to See It

The breeding season from February to April offers the best opportunity to observe this species, as birds are actively nesting and more conspicuous. Travellers should visit mature rainforests and humid deciduous forests throughout its range, with particular success likely in cardamom plantations under native shade trees. The species is common in most suitable habitats across its distribution, making it a reliable sighting for those exploring tropical forests from India and Sri Lanka through Southeast Asia to the Greater Sundas.

Photography Tips

The brilliant iridescent blue plumage of males, particularly the ultramarine-blue with lilac reflections on upperparts, requires careful exposure metering to capture accurately without losing detail in the deep black underparts. Position yourself in mature forest canopy areas where these birds naturally forage. The contrast between male and female plumage makes photographing both sexes rewarding for documenting sexual dimorphism. Early morning light will best reveal the glossy, iridescent qualities of the male's blue plumage, while the bird's arboreal habits mean patience and a telephoto lens are essential for successful photography.
