The Louisiade monarch is a species of bird in the family Monarchidae endemic to Papua New Guinea. It is found in the Louisiade Archipelago. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist shrubland. It is threatened by habitat loss.
Region
Louisiade Archipelago, Papua New Guinea
Typical Environment
Occurs on several of the larger islands in the Louisiade group, notably Misima, Tagula (Sudest), and Rossel (Yela). It inhabits subtropical and tropical moist lowland forests, forest edges, and tall secondary growth. Birds may also use overgrown gardens and selectively logged forest, provided sufficient canopy and midstory remain. The species is patchy where primary forest has been heavily cleared but can persist in mosaic landscapes. It is largely tied to humid, well-vegetated habitats with dense foliage for foraging.

The Louisiade monarch is a small monarch flycatcher restricted to the Louisiade Archipelago of Papua New Guinea. It favors shaded forest interiors and edges, gleaning insects from leaves and making short sallies after flying prey. Taxonomically it has been placed in both Monarcha and Symposiachrus. Ongoing habitat loss on its limited island range poses the main threat.
Temperament
solitary and territorial
Flight Pattern
short rapid wingbeats
Social Behavior
Typically found singly or in pairs within well-defined territories. It forages methodically through the midstory, often sallying to snatch prey from foliage or in mid-air. During breeding, pairs build small cup nests in forks of slender branches and share incubation and chick-rearing duties.
Migratory Pattern
Resident
Song Description
Song consists of thin, high-pitched whistles interspersed with short, sharp ticks. Calls are simple contact notes used to maintain pair cohesion and advertise territory in dense forest.
Plumage
A contrasting black-and-white monarch; males show glossy black head and upperparts with clean white underparts and a distinct white wing patch. Females are similar but may appear slightly browner or duller on the upperparts. The tail is dark with pale edging and the throat and breast are bright white. Plumage is crisp with sharp borders between dark and light areas.
Diet
Feeds primarily on small insects such as beetles, flies, moths, and caterpillars. It gleans prey from leaves, twigs, and bark and will make quick aerial sallies after flying insects. Occasional small spiders and other arthropods are also taken. Foraging is deliberate, using short hops and brief hover-gleans to inspect foliage.
Preferred Environment
Most often forages in the shaded midstory and lower canopy of moist forest. It also uses forest edges and taller secondary growth with tangled vines and broadleaf understory. In disturbed areas it concentrates along remnant riparian strips and dense thickets.
