分布与栖息地
The species is found in dense to open forest throughout the island plateau, both in forest dominated by Pisonia and Pisonia/Xylosma, and in Timonius thicket, also occurring in Pandanus–Thespesia–Argusia embayment forests and coconut groves on the beaches. It is omnivorous and appears to be an opportunistic feeder, taking advantage of seasonal increases in prey. It forages in the leaf-litter, gleaning items such as skink Emoia cyanura eggs from the undersides of fallen leaves, large nematodes, beetles, moths, spiders, dead caterpillars, land snails and small insects. The breeding season is long, extending from late July to mid February (double broods are not uncommon) and clutch-size is 2–3. Helpers may provide extraparental care such as defending eggs and chicks from crabs and rats. Based on a small sample, adult annual survival is at least 43%, and reproductive success is a minimum of 0.95 chicks surviving to one month old per pair, per annum.<p>The population of the species was severely affected by a failed rodent eradication campaign on Henderson in 2011, but had returned to pre-eradication levels by 2015.

Arfak Honeyeater
Melipotes gymnops
A medium-sized honeyeater of montane forest and edge on the Bird’s Head of New Guinea. Dark gray with a black head and chest. White streaking from the upper belly gets broader, to all pale in the base of the tail. The most prominent feature is the large yellow patch of bare facial skin centered around the eye. No other co-occuring honeyeaters have this color and shape facial patch. Call, a long croaking whistle “Wuueeeeeeuuuuu!” first rising then falling back down.

Streak-breasted Bulbul
Hypsipetes siquijorensis
A medium-sized bird of foothill forest and edge as well as more open wooded areas. Fairly large for a bulbul. Dark brown above with a pale belly and a warm brown chest and throat with pale streaking. Note brown cheek and black crown that can be raised into a spiky crest. Similar to Philippine Bulbul, but larger, with a longer bill, a black crown, and a paler throat and chest. Voice consists of rather unpleasant grating chatters and harsh downslurred squeals.

Rufous-winged Antshrike
Thamnophilus torquatus
Medium-sized antshrike. Males have black-and-white barring on the breast and tail and a black crown that fades to gray on the back. Females have pale cinnamon underparts, a rusty crown and tail, and gray cheeks. Both males and females have rusty wings. Inhabits the understory of savanna woodlands, thickets, and scrub. The song is loud with a series of accelerating notes.
