Bar-shouldered Dove
Geopelia humeralis
Medium sized dove with a scaled metallic copper patch on the hind-neck. Gray face and neck, with a pinkish belly. Juveniles have a less obvious patch on the neck, and with more muted plumage and an eye-line could be confused with the much larger Common Bronzewing. Forages on the ground in small groups. This species is abundant in woodlands, towns, parks and gardens in northern Australia. Voice is often a repeated 6-note phrase (low-low-high low-low-high).
识别特征
The dove has a blue-grey breast with chequered brown-bronze wings. The nape is similar to that of the peaceful dove in that the nape feathers are striated but differs in that the bar-shouldered dove does not have striated throat feathers like the peaceful dove. Furthermore, the nape feathers are copper in colour. These doves are also often confused with the introduced and common spotted turtle dove. The eye ring tends to be grey but red-brown when breeding. The juveniles are duller in colour.<p>Doves are often found in pairs, groups or large loose flocks and are seen commonly feeding on the ground feeding on seeds. Flight is direct and swift and wings whistle while the birds are in flight.

分布与栖息地
Bar-shouldered doves are usually found in thick vegetation where water is present, damp gullies, forests and gorges, mangroves, plantations, swamps, eucalyptus woodlands, tropical and sub-tropical scrubs and river margins. They can be found in both inland and coastal regions. The bar-shouldered dove is found throughout the east coast from southern New South Wales (with increasing numbers in the Blue Mountains and Illawarra regions), north to Cape York Peninsula and west to the Pilbara region (about Onslow, Western Australia). They have been observed with increasing frequency in southern Australia (specifically north-western Victoria) but may have been displaced in other natural locations by introduced species[citation needed]. They have also been observed in the Torres Strait and are also found in other countries of the South Pacific region, such as Papua New Guinea.

White-browed Brushfinch
Arremon torquatus
Handsome brushfinch found in humid forest along the east slope of the Andes in Bolivia, northwestern Argentina, and far southeastern Peru. It has an olive back, black mask, striped head, and white throat. In the northern part of its range it also has a black breast-band. Similar to Gray-browed Brushfinch, but has white (not gray) eyebrow; also note range. Inhabits thickets in forest understory. Typical song is a seesawing series of three to four high-pitched whistles.
Taiwan Partridge
Arborophila crudigularis
Subtly patterned sphere of a bird; the only hill partridge (genus Arborophila) on Taiwan, where endemic. Black-and-white facial pattern is diagnostic, unlikely to be confused with any other native bird. Female’s facial markings slightly weaker than male’s. Forages on the ground in small groups. Inhabits broadleaf and mixed forests in hills and mountains, where it forages quietly in the leaf litter. Gives loud, echoing tremulous songs, usually early in the morning and late in the afternoon. Generally shy but approachable where habituated at feeders.
Northern Royal Albatross
Diomedea sanfordi
Huge albatross of the Southern Ocean; breeds mainly on Chatham Islands in New Zealand, but ranges widely. Especially numerous in Humboldt Current off western South America. Easily separated at a distance from smaller albatrosses by white back. From the Wandering Albatross complex (including Snowy, Tristan, Antipodean, and Amsterdam Albatrosses) by uniformly dark upperwings at all ages with otherwise clean white appearance (including mostly white tail, occasionally with small black markings). This combination of features is never shown by Wandering-types, and Northern Royal never has dirty brownish markings on head and body or a mostly black tail. At close range, note the diagnostic narrow black “lips” on cutting edge of bill, lacking on Wandering-types. Also note slightly longer, thinner bill and shallower forehead, which give Northern Royal a “snoutier” look than Wandering-types. Very similar to Southern Royal Albatross; best separated by uniformly dark upperwings, especially on the leading edge. Youngest Southern Royals can also have dark upperwings with very narrow white leading edge; can require close scrutiny or good photographs to identify with confidence. Range averages further north than Southern Royal, but some overlap.
