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.
Identification
The Japanese pygmy woodpecker is 13–15 cm (5.1–5.9 in) long. The crown is grey-brown. A white supercilium starts above the eye and continues to the neck and breast. The ear coverts are brown, and there is a white moustachial stripe and a grey-brown malar stripe. The chin and throat are white. The mantle and back are dark brown, with white bars. The upperwing coverts and flight feathers are brownish-black and have white bars. The breast has a brownish suffusion. The breast, flank and belly have variable streaks. The tail is blackish, with white bars on its outer feathers. The iris is chestnut, the beak is blackish and the legs are grey. The male has a small red mark on the side of its nape, and the female does not. The female's beak, wings and tail are longer than the male's. The juvenile bird's throat is often streaked. The bird becomes smaller and darker from the north of its range to the south. It's call is a high "tsi-tsi-tsi" and it has a quick drum.

Range and habitat
This woodpecker is found in Korea, northeastern China, southeastern Siberia, Sakhalin, Japan and the Ryukyu Islands.

Behavior
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.

Crimson Finch
Neochmia phaeton
Elegant, long-tailed finch, adult male brown above, intense crimson below, with a cherry-red face and small pale spots on the side of the chest. Birds in New Guinea and Cape York with white belly, those elsewhere in Australia with black. Female duller, with only red face. Juvenile mostly brownish with dark bill but note long tail. Star Finch has shorter tail, greener plumage. Inhabits tall grass areas, especially with Pandanus (palm-like tree with leaves attached in a corkscrew pattern).
Pink Cockatoo
Cacatua leadbeateri
Distinctive cockatoo found in a wide variety of habitats across inland Australia, typically favoring dry woodlands, where it feeds on seeds. Relatively small, with pink underparts and white upperparts. Magnificent, long white crest has colorful band of red at base, in subspecies leadbeateri inset with another band of yellow. In flight, pink underwings evident. Often observed feeding on the ground beside roads. Call a wavering, high-pitched note.
Smoky Warbler
Phylloscopus fuligiventer
Dark sooty leaf warbler with a pale brow stripe and no wingbars. Yellow wash to the underparts tends to be absent in worn birds. Extremely similar in appearance to Dusky Warbler, which averages larger and darker overall, and has a longer, brighter brow stripe. Breeds in scrubby areas above the treeline and moves downhill into shrubby and grassy foothill and lowland areas. Forages low on the ground, often around rocks or water. Song is a repetitive series of liquid notes. Calls are dry, hard “chuck” or “tick” notes.
