Eurasian Three-toed Woodpecker
Picoides tridactylus
Distinctive black and white woodpecker with two large white stripes on the face. Males have a yellow crown and no red plumage elements. Patterning varies across range, with varying amounts of black on the back and sides. Shy and retiring, found in old coniferous and mixed forests, especially with spruces and lots of dead trees. Often forages by stripping bark off trunks to find the invertebrates underneath. Gives a hard, yapping chip, as well as a rattled series.

The Eurasian three-toed woodpecker is 21–22 cm (8.3–8.7 in) in length, just a little smaller than the great spotted woodpecker. The adult has black and white plumage except for the yellow crown of the male. Neither sex has any red feathers. It has black wings and rump, and white from the throat to the belly; the flanks are white with black bars. The back is white with black bars, and the tail is black with the white outer feathers barred with black. Juveniles of both sexes have a yellow crown.<p>The voice call of the Eurasian three-toed woodpecker is a kik or chik<p>The breeding habitat is coniferous forests across the Palearctic from Norway to Korea. There are also populations in the Alps and the Carpathian Mountains.<p>Three-toed woodpeckers nest in a cavity in a dead conifer or sometimes a live tree or pole. The pair excavates a new nest each year.<p>This bird is normally a permanent resident, but northern birds may move south and birds at high elevations may move to lower levels in winter.<p>Three-toed woodpeckers forage on conifers in search of wood-boring beetle larvae or other insects. They may also eat fruit and tree sap.<p>These birds often move into areas with large numbers of insect-infested trees, often following a forest fire or flooding.
分类信息
The Eurasian three-toed woodpecker was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae. He coined the binomial name Picus tridactylus. The type locality is Sweden. The specific epithet is from the Ancient Greek tridaktulos meaning "three-toed" (tri- is "three-" and daktulos is toe). The species is now placed in the genus Picoides that was introduced by the French naturalist Bernard Germain de Lacépède in 1799. The Eurasian three-toed woodpecker was formerly considered conspecific with the American three-toed woodpecker (Picoides dorsalis).<p>Eight subspecies are recognised:<p>The subspecies P. t. funebris is sometimes treated as a separate species, the dark-bodied woodpecker.

Amami Woodcock
Scolopax mira
Furtive, large, ground-dwelling shorebird endemic to the broadleaf forests of northern Okinawa Island and the Amami Islands. Similar to Eurasian Woodcock but darker overall, with notably longer legs and a thicker bill base. Patch of bare pinkish skin around the eye is diagnostic but absent in winter. Black bands on the top of the head not as thick and conspicuous as in Eurasian, which is a winter visitor. Like other woodcocks, displays both on the ground and in circular aerial displays. Flushes slowly and directly ahead.
Bougainville Hooded Whistler
Pachycephala richardsi
A distinctive whistler of dark, dingy appearance. Golden-olive above and bright yellow below, with a black hood and chest. Female golden below and olive above, with a gray head and a white throat. Mainly found in primary forest above 1200 meters of elevation, but does occasionally wander lower. Oriole Whistler also occurs but male has a bright golden throat, neck, and belly, and female is dark brown above and beige streaked with ruddy below. Bougainville Hooded Whistler’s voice is a mix of loud, almost electronic staccato whistles.
Yellow-bellied Elaenia
Elaenia flavogaster
Rather bulky small flycatcher, widespread in tropical lowlands. Fairly common in overgrown brushy clearings, savannas, and other semi-open areas with scattered bushes. Looks like many other small flycatchers, and where multiple species of elaenias occur it is often not possible to identify birds to species. On Yellow-bellied, note its spiky, white-based crest (rarely held flattened), burry drawled call, whitish wingbars, and pale yellow belly; does not flick its wings or tail.
