Yellow-bearded Greenbul
Criniger olivaceus
A fairly large and distinctive rainforest greenbul. Mostly dark olive-green, with a brown tail and some blue-gray bare skin around the eye. The bright yellow throat feathers are slightly puffy. Generally uncommon and inconspicuous in the understory and at middle levels of lowland rainforest. Similar in appearance to Western Bearded-Greenbul, but smaller, with a less puffy throat and no gray in the plumage. Similar to Red-tailed Greenbul, but has a yellow rather than pure white throat. Somewhat similar to Icterine Greenbul, but larger and much darker on the breast and belly. The song is a series of 3-4 chatty notes, sometimes ending on an upward inflection; similar to the song of Red-tailed Greenbul, but lower-pitched and less cheerful.
Taxonomy
Alternatively, the yellow-bearded greenbul has been classified in the genus Xenocichla (a synonym for Bleda) and has also been considered as conspecific with the white-bearded greenbul. Alternate names for the yellow-bearded greenbul include the olive bulbul, olive greenbul, olive-bearded bulbul, yellow-bearded bulbul, yellow-throated olive bulbul and yellow-throated olive greenbul. The name 'olive bulbul' should not be confused with the species of the same name, Iole virescens.

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.
