Taxonomy

Forms a superspecies with Frill-necked Monarch, Ochre-collared Monarch and Pied Monarch and was often considered conspecific with the first two.

Subspecies

There are 6 subspecies[1]:

  • A. t. telescopthalmus:
  • North-western New Guinea, Salawati and Misool islands
  • A. t. batantae:
  • Batanta and Waigeo islands (New Guinea)
  • A. t. aruensis:
  • Aru Islands (New Guinea)
  • A. t. lauterbachi:
  • North coast of south-eastern New Guinea (Milne Bay to Huon Peninsula)
  • A. t. harterti:
  • Southern New Guinea (Mimika River to Purari River); Boigu Island
  • A. t. henkei:
  • Coastal south-eastern New Guinea (Hall Sound to Orangerie Bay) - other authorities treat this subspecies as an intergrade between harterti and lauterbachi

Habitat

Rainforest, gallery forest, forest edge and secondary growth.
Occurs in lowlands and hills up to 1500 m.

Behaviour

Diet

Feeds on arthropods like crickets and grasshoppers.
A conspicuous species, usually seen singly or in pairs. Often acts as a core member in mixed-species flocks, with Spot-winged Monarch in the same flock.
Forages at mid-level and lower canopy. Gleans prey from leaves and branches, also feeds in dense thickets. Darts out with fanned tail after flying insects. Females usually higher up, making more aerial sallies than males.

Breeding

Breeding season varies with locality, probably an opportunistic breeder. A monogamous species, defending its territory all year. Erects its frill on hindneck when alarmed or displaying.
The nest is a miniature hanging cup made of loosely interwoven fine twigs and bound with spider webs. It's slung between hanging creepers or branches, often in a fairly open place, 2.4 to 12 m above the ground. Lays 2 eggs.

Movements

A sedentary species.
