Alternative names: Black-headed Pitohui; Lesser Pitohui; Lesser Wood-shrike

Pitohui dichrous

Identification

22 - 23cm, 8.6-9 inches. 67–76 g

Adult

  • Black head, chin, throat and upper breast
  • Rufous-chestnut uperparts
  • Black tail and upperwing
  • Bright rufous-chestnut rest of underparts
  • Reddish-brown eye
  • Dark brown to black bill
  • Legs black
  • Sexes similar.

Juvenile

Similar species

Similar to some subspecies of Northern Variable Pitohui and Southern Variable Pitohui but note bright rufous plumage.

Distribution

Endemic to New Guinea. Also on Yapen Island.
Locally fairly common.

Taxonomy

Clements accepts two subspecies[1]:

  • P. d. dichrous
  • Mountains of n New Guinea and Yapen I.
  • P. d. monticola
  • Mountains of central New Guinea

However other authorities[2],[3],[4] treat this species as monotypic.

Habitat

Forests and secondary growth, forest edges, sometimes low trees on beaches and mangroves Found at 350 - 1700m, locally up to 2000m and at sea level

Behaviour

Resident species

Diet

Feeds mainly on fruit but takes also some insects and grass seeds.
Chicks fed with invertebrates and berries.

Breeding

Breeding recorded from October to February. The nest is a cup made of curly vine tendrils, suspended from slender branches around 2m above the ground. Lays 1 - 2 creamy or rose eggs, speckled light and dark brown to black, with background light grey patches.
Upwards of three adults are known to feed chicks at one nest, with four or five defending the nest.

Vocalisation

Song is irregular. A series of combinations of 3–7 harmonic whistles, with up- and downslurs of varying length interspersed with reluctant spaces. Normally starting with 2 notes of thesame pitch followed by upslur. Other sounds include “tuk tuk w’oh tuw’uow”, two noisy whistles, “woiy, woiy”, two downslurred whistles, “tiuw tow”; three ascending whistles getting louder, “hui-whui-whooee” and six fast, identical upslurs.

Toxicity

The skin and feathers contain powerful neurotoxic alkaloids of the batrachotoxin group (also secreted by the Colombian poison dart frogs, genus Phyllobates). It is believed that these serve the birds as a chemical defence, either against ectoparasites or against visually guided predators such as snakes, raptors or humans. (Dumbacher, et al., 1992) The birds probably do not produce batrachotoxin themselves. It is most likely that the toxins come from the Choresine genus of beetles, part of the bird's diet. (Dumbacher, et al., 2004)
