It is the largest fairy-wren. It is 13–16 cm (5.1–6.3 in) long and weighs 12–17 g (0.42–0.60 oz).

Males of the nominate race have light royal blue crowns. The forehead, lores, and the side of the head up till the narrow collar is black. The upper back, along with the scapulars and uppertail-coverts is a deep turquoise-blue, with the lower back being blue-black. The upperwing and the tail are blackish-blue with tinges of blue, and the throats and underparts are a navy blue in color. It has dark brown eyes, black bill, and dark grey-brown legs. Females of the nominate race have a head that looks similar to the male, but have chestnut upperparts, white underparts, deep blue throats, and a black tail with whitish tips. They also have lighter are more mid-brown legs. Juveniles look like females, but have a dusky head, rusty brown upperparts, and entirely white underparts. M. c. mysorensis differs slightly in appearance with its crown being cobalt blue instead of royal blue, and M. c. bonapartii is slightly darker than the nominate race.[3]

It is found on the island of New Guinea and the Aru Islands. It is found in tropical lowland, forests, wetlands, and degraded former forests. They inhabit dense secondary growth that occurs at the edges of forest, along with forest openings, riversides, roadsides and overgrown gardens. They are not as affected by habitat disturbance and appear to like disturbed habitats like gardens and parks. [3][4]
