Eurasian Wigeon
Mareca penelope
Breeding males are beautiful and distinctive with rich reddish-brown head, buffy forehead, pearly gray body, and pinkish breast. Look for large white wing patches in flight. Females are plainer warm brown overall, with a small pale bill. Very difficult to distinguish from female American Wigeon; note warmer brown head on Eurasian with little contrast between head, breast, and sides. Also look for dirty grayish, not bright white, underwings in flight, but this can be difficult to judge, especially at a distance. Widespread and common in Eurasia, breeding at northern latitudes and wintering south to central Africa and Southeast Asia. Typically in flocks on lakes and wetlands, often grazing in nearby fields. Regular winter visitor to North America, especially on the west coast, usually in very small numbers among flocks of American Wigeon.
识别特征
This dabbling duck is 42–52 cm (17–20 in) long with a 71–80 cm (28–31 in) wingspan, and a weight of 500–1,073 g (1.102–2.366 lb). The breeding male has grey flanks and back, with a black rear end, a dark green speculum and a brilliant white patch on upper wings, obvious in flight or at rest. It has a pink breast, white belly, and a chestnut head with a creamy crown. In non-breeding (eclipse) plumage, the drake looks more like the female. The female is light brown, with plumage much like a female American wigeon. It can be distinguished from most other ducks, apart from American wigeon, on shape. However, that species has a paler head and white axillaries on its underwing. The female can be a rufous morph with a redder head, and a gray morph with a more gray head.
分类信息
The Eurasian wigeon was described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae under the binomial name Anas penelope. Anas is the Latin word for "duck", and penelope refers to a duck that was supposed to have rescued Penelope when she was thrown into the sea. Her name derives from Ancient Greek πήνη pene, "braid" and ὤψ ops "appearance", from the ruse she used to deter suitors while her husband Ulysses was absent.

分布与栖息地
It breeds in the northernmost areas of Europe and the Palearctic. It is the Old World counterpart of North America's American wigeon. It is strongly migratory and winters further south than its breeding range. It migrates to southern Asia and Africa. In Great Britain and Ireland, the Eurasian wigeon is common as a winter visitor, but scarce as a breeding bird in Scotland, the Lake District, the Pennines and occasionally further south, with only a handful of breeding pairs in Ireland. It can be found as an uncommon winter visitor in the United States on the mid-Atlantic and Pacific coasts. It is a rare visitor to the rest of the United States except for the Four Corners and the southern Appalachians.

New Britain Kingfisher
Todiramphus albonotatus
A medium-sized blue-and-white kingfisher with a pale blue crown, a black eye mask, and a mostly white body with blue wings and tail. Female has blue rump, while male’s is white. Bill is entirely black. Prefers lowland primary forest up to 1000 meters of elevation, but also recorded in degraded forest. Forest Kingfisher is slightly larger with a green back and rump and a more prominent white spot in front of the eye. Sacred Kingfisher and local race of Pacific Kingfisher are more buff in pale areas and overall more greenish-blue than pure blue. Beach Kingfisher is much larger and overall paler. New Britain Kingfisher’s call is a rapidly descending “kee-ku-ko-ko” or a light cackling trill.
Stripe-tailed Hummingbird
Eupherusa eximia
Distinctive, medium-sized hummingbird found in foothills and highlands. Favors humid evergreen forests and shade-coffee plantations. Mainly feeds at low to middle levels, darting quickly among flowers and flashing open its tail to reveal white stripes. Both sexes have a bright rusty panel in the wings, which appears as a blur when hovering. Male is brilliant green overall. Female is pale gray below and has less white in the tail.
Chucao Tapaculo
Scelorchilus rubecula
Fairly common to common in native temperate forest, adjacent shrubbery, wooded patches, and thickets along rivers and streams, especially with bamboo. Loud ringing song is commonly heard, but calling birds can be elusive. At other times can be confiding, walking out at close range as if curious, usually with tail cocked. Plumage distinctive, with bright rusty eyebrow, throat, and breast. Compare with the larger and fatter Chestnut-throated Huet-huet.
