Japanese Pygmy Woodpecker
Yungipicus kizuki
Small black-and-white woodpecker with round-headed, short-billed profile. Both sexes have a pale, lightly streaked belly and white bars on the back, but only the male has a tiny red fleck at the back of the eyebrow. Often forages on thin twigs and outreaching branches too slender for other woodpeckers, hanging upside down like a tit or nuthatch. Slightly larger Gray-capped Woodpecker is longer-billed, with a buffy belly and different head pattern. Gives extremely high, thin “tsi tsi tsi” calls and a single quick, echoing drum.

行为
The Japanese pygmy woodpecker occurs in pairs and mixed-species foraging flocks, searching on trees for invertebrates, such as spiders, caterpillars, ants and aphids, and berries. Its calls are khit and kzz notes, and it drums weakly in short bursts. Breeding starts in March in southern Japan and in late May in northern Japan. A nest hole is excavated in a dead branch. The eggs are white, measuring about 19 mm (0.75 in) by 15 mm (0.6 in). Five to seven white eggs are laid and then incubated for 12 to 14 days. Fledging occurs after three weeks.

A small green-backed songbird with a bold white eye-ring, a black face, a yellow throat, a white belly, and a yellow base to the undertail. Occurs in forest and nearby secondary growth in lowlands and foothills, sometimes in small groups. Confined to Seram. Conspicuous white eye-ring separates it from all other species except Warbling and Ambon White-eyes, from which it differs in its black forehead. Gives chattering “twee” call notes and a short, rapidly undulating twittering song: “titli-titli-titli.”
