About Cyanoptila cyanomelana (Temminck, 1829)
The Blue-and-White Flycatcher, Cyanoptila cyanomelana (Temminck, 1829), is a large flycatcher, measuring 16–17 cm in length with an average weight of 25 g, and has a striking, beautiful appearance. Adult males are deep cobalt blue, with black coloring extending from the face down to the upper breast and flanks; the rest of their underside is white. White is also present at the base of the outer tail feathers. Immature males have the same blue wings as adult males, but are brown on all other parts of the body. On average, females are smaller than males. Their head, face, and most of their upperparts are grey-brown, and the lower central portion of the throat is pale beige-white; young males closely resemble females. Females have a smaller-headed profile than other brown flycatchers found within their range. The species' song is a short series of whistles with a melancholic sound. Blue-and-white flycatchers breed in primary and secondary lowland and submontane forests, including taiga, wooded slopes, and gullies, at elevations up to 1200 m. They also breed in riverine thickets and plantations. Outside of the breeding season, they occupy coastal woodland, scrub, parks, and gardens. In Borneo, they winter at elevations up to 1850 m in forested hills, lower montane forest, plantations, and logged lowland forest. These flycatchers are most active during the morning.
