Taxonomy

Three subspecies recognized[1]:

  • A. i. incerta in the Arfak Mountains of western New Guinea
  • A. i. olivascentior from Wandamman and Weyland to Snow Mountains (western New Guinea)
  • A. i. brevicauda in the Mountains of eastern and southeastern New Guinea

Habitat

Found in montane forest.
Occurs mainly at 1200 to 2750 m, locally down to 900 m.

Behaviour

Diet

Feeds on insects.
Forages on the forest floor, making short runs with brief stops to glean. Foraging pattern similar to that of a plover.

Breeding

One nest was recorded in mid-October, another in early January. The nest is an open cup made of moss, grass and fine rootlets. One was placed on the ground close to a moss-covered tree root, the other 1.2 m above the ground in a tree hole. Lays one egg.
