Dwarf Fruit-Dove
Ptilinopus nainus
A tiny fruit dove of lowland and foothill rainforest. Mainly green with bright yellow vent. Male has a distinctive purple mark across the chest and a pale crescent above the shoulder. Often found in pairs and sometimes mixing with other fruit-dove species. Feeds on fruit and also nectar. Similar to female Claret-breasted and White-breasted Fruit-Doves, but Dwarf Fruit-Dove is smaller and has yellow edging to the wing feathers. Call, a distinctive falling and rising, “oh-wah!” repeated several times.
Identification
With a total length of 13–15 cm (5.1–5.9 in), it is the shortest pigeon or dove in the world, but as it is thickset, several other species weigh less. Its plumage is overall green, but with contrasting yellow undertail coverts, and narrow bars to the wings. The inner wing-coverts and secondaries are more bluish in color compared to the rest of the body. This bluish-green coloring is most prominent on the scapulars, which are the body feathers that cover the top of the wing when the bird is at rest. The males differ in color and plumage from the female. The males have a dark purple patch on the belly and tend to have a gray patch on both sides of their upper breasts. Both males and females have a yellowish-green beak and purplish-red legs, in addition to a yellow area on their abdomen and undertail coverts. Juvenile fruit doves resemble the coloring of females, but have yellow fringes on most of their plumage. Eventually this yellow fringe will disappear, and the birds will resemble their gender colorings. These fruit doves will often be found in pairs of their own species, and sometimes intermingling with other fruit dove species.<p>Dwarf fruit doves will communicate with each other using a high-pitched, slow, soft, and prolonged up slur. With a one-second pause, the sound is repeated about six times. Their call resembles a “oh-wah” sound.

Range and habitat
The habitat of the dwarf fruit dove is forests in the lowlands and foothills of New Guinea, excluding northwestern New Guinea and the north coast of southeastern New Guinea. Additionally, they are found in the Raja Ampat islands off the coast of Northwestern New Guinea. They have been most found in hills up to 1100 meters. They can also be found at Varirata National Park in New Guinea.
- Migration
- Nomadic movement
Behavior
The dwarf fruit dove's nests have been found in September and November. Nests are found at varying heights in small trees from 3 meters above ground to 12 meters above ground. These nests are built by the female bird using twigs and dead leaves collected by the male.<p>90 percent of their diet comes from fruit, whereas the other 10 percent comes from nectar. The dwarf fruit dove can be considered a frugivore and nectarivore.

Other Birds
White-breasted Parrotbill
Paradoxornis ruficeps
Chunky parrotbill with a large head and a relatively short tail. Very similar in appearance to Rufous-headed and Pale-billed Parrotbills, but note brighter coloration and whiter underparts. Forages in small flocks, often with other species, in foothill forest bamboo clusters; also in reedbeds and tall grass. Song is a descending series of 4-5 whistles: “wee-dee-dee-dee-dee.” Calls include a loud, sputtering machine-gun chatter.
Gray-backed Sparrow-Lark
Eremopterix verticalis
A small, compact finch-like sociable lark that is both resident and nomadic, although movements are poorly understood. The sexes differ in plumage: the male has a gray-brown back and wings with a scalloped pattern, and a black head with bold white ear patches that reach the back of the neck; the streaky female is variable depending on geographic range, but always has a dark belly patch and tends to be paler than other female sparrow-larks. Flocks of 20 to 100 birds (often mixed with other sparrow-larks or with Stark’s Lark) can appear in grassy patches in semi-arid shrublands and fallow fields. They shuffle along in bare patches foraging for seeds and insects.
White-bellied Thicket-Fantail
Rhipidura leucothorax
A medium-sized, long-tailed bird of lowland and foothill wooded thickets. Blackish plumage with short white eye-brow, white patch on the side of the throat and prominent white tail tips. Also white-spotted chest and wing bars. Secretive and difficult to see. Keeps to cover with tail often cocked and fanned. Similar to Black Thicket-Fantail, but White-bellied unsurprisingly has a white belly. Also similar to Sooty Thick-Fantail but has the white tail tips. Voice, a falling note followed by a high-pitch ringing note “joo-wii!”
