Red-collared Lorikeet
Trichoglossus rubritorquis
Large lorikeet. Very colorful, with a bright orange breast and neck, blue/black belly and head, and red bill. Very conspicuous, often observed calling loudly while flying overhead or feeding. Varied Lorikeet is much smaller and shorter-tailed; no range overlap with Rainbow Lorikeet, which has a yellow neck and red breast. Found in a wide range of habitats. In the evening and early morning can be seen roosting in very large, noisy flocks.
识别特征
The red-collared lorikeet measures around 26 centimetres (10 in) long. The feathers of the head and throat are dark brown with blue shafts. There is an orange-red band on the back of the neck. The chest is orange with red. The base of the hindneck is dark blue. The wings are green. The bill is red. The legs and feet are grey-brown. The sexes are similar in plumage while the juvenile has duller plumage and a dark bill.<p>The red-collared lorikeet is distinguished from the rainbow lorikeet by the latter's green rather than red nape, the lack of a blue mantle and more yellow-green underparts. The two may both occur where their ranges abut east of the Gulf of Carpentaria.
分类信息
Nicholas Aylward Vigors and Thomas Horsfield described the red-collared lorikeet in 1827. The species name is derived from the Latin words ruber "red" and torquis "neck".<p>Molecular analysis using mitochondrial cytochrome b showed the red-collared lorikeet is most closely related to a lineage that gave rise to the marigold lorikeet and sunset lorikeet of Indonesia. It is more distantly related to the rainbow lorikeet, the two distinct lineages colonising Australia independently. <p>No subspecies are recognised, and there is no regional variation.<p>"Red-collared lorikeet" has been designated as the official common name for the species by the International Ornithologists' Union (IOC). Other common names include orange-naped lorikeet and (incorrectly) blue bonnet.

分布与栖息地
The red-collared lorikeet is found across northern Australia, from King Sound in Western Australia to the Gulf of Carpentaria. It lives in woodland, open forest and rainforest, and has adapted to urban environments readily, being found in towns and cities. The species is sedentary, though follows food supply, such as banksias in flower in April and May on Groote Eylandt.

Niceforo's Wren
Thryophilus nicefori
Endangered songbird restricted to the western slopes of the northern part of Colombia’s eastern Andes. Note the white spectacles, striped face, and barred wings and tail. Very similar to the widespread Rufous-and-white Wren, but duller brown, lacking rich chestnut tones in the plumage, and its song tends to be faster and higher in pitch. Range is also helpful for ID, since the two species have limited, if any, overlap. Skulks in the understory of dry to semi-humid forest as well as in shady coffee and cacao plantations.
African Citril
Crithagra citrinelloides
A small seedeater with a sharp bill and a forked tail. The upperparts are olive-green and the underparts yellow. Males have a black face and plain yellow underparts. Females have a plain face, but are heavily streaked below. Found at middle and high elevations in a variety of habitats including forest edge, gardens, cultivation, moist scrub, and woodland. Usually in small flocks. Similar to Southern Citril, but there is virtually no overlap in range, and the male is easily separated by its black face. The song is a fast jumble of high-pitched twitters and whistles.
Crimson Chat
Epthianura tricolor
Brightly colored, terrestrial songbird of arid inland Australia. Breeding male has crimson crown and belly, gray back, black mask, white throat, pale eye, and blackish wings with narrow pale wingbars. Nonbreeding male more muted, with only hints of crimson. Female similar to nonbreeding male but paler around the face. Usually seen in small groups hopping along the ground in open areas.
