The diet of the hooded pitohui is dominated by fruit, particularly figs of the genus Ficus, grass seeds, some insects and other invertebrates,[10] and possibly small vertebrates.[19] Among the invertebrates found in their diet are beetles, spiders, earwigs, bugs (Hemiptera, including the families Membracidae and Lygaeidae), flies (Diptera), caterpillars and ants.[28][29] They feed at all levels of the forest, from the forest floor to the canopy,[10] and are reported to do so in small groups, presumably of related birds.[30] The species also regularly joins mixed-species foraging flocks, and on Yapen and between 1,100–1,300 m (3,600–4,300 ft) above sea-level it will often act as the flock leader. This leadership role, and indeed their participation in mixed flocks, is not true across all of their range however.[31] Breeding Little is known about the breeding biology of the hooded pitohui and its relatives due to the difficulties of studying the species high in the canopy of New Guinea.[30] Nests with eggs of the hooded pitohui have been found from October through to February.[10] The nest that has been described was 2 m (7 ft) off the ground. The nest is a cup of vine tendrils, lined with finer vines and suspended on thin branches.[10][30] The clutch is one to two eggs, 27 mm–32.8 mm × 20.5 mm–22.2 mm (1.06 in–1.29 in × 0.81 in–0.87 in), which are creamy or pinkish with brown to black spots and blotches and faint grey patches; in one egg all the markings with at the larger end.[10][32] The incubation period is not known, but the species is thought to be a cooperative breeder, as more than two birds in a group have been observed defending the nest from intruders and feeding the young. Young birds, which are covered in white down as nestlings before developing their adult plumage,[33] have been observed being fed acorn-shaped red berries and insects. Young birds will make a threat display when approached in the nest, rising up and erecting their head feathers. As chicks develop directly into adult plumage, it has been suggested tha
