分类信息
The duchess lorikeet was formally described in 1879 by the English clergyman and ornithologist Henry Baker Tristram from a specimen collected at Makira Harbour, San Cristoval, Solomon Islands. Tristam coined the binomial name Charmosyna margarethae. The specific epithet was chosen to honour Princess Louise Margaret of Prussia who became the Duchess of Connaught and Strathearn when she married Queen Victoria's son Prince Arthur in 1879. The lorikeet was moved to its own genus, Charmosynoides, based on a molecular phylogenetic study published in 2020. The name Charmosynoides is a combination of the genus name Charmosyna with the Ancient Greek -oides meaning "resembling".

分布与栖息地
The species is found only on Bougainville Island and 6 islands in the Solomon Islands. It is a localised species that is absent from large areas of habitat in its range that are potentially suitable for it. It is most often found in lower montane forest and in coconut plantations. It is found from sea level to an elevation of 1,350 m (4,430 ft) asl. It may be nomadic and inhabit habitats at different altitudes.

Ochre-bellied Flycatcher
Mionectes oleagineus
Rather plain, inconspicuous small flycatcher of humid tropical forest; also wanders into adjacent clearings and semiopen areas with fruiting bushes and trees. Usually found singly at lower to middle levels in shady understory and at times with mixed-species feeding flocks. Feeds mainly on fruit, plucked by short sallies. Plain olive plumage with ochre belly is distinctive. Also has habit of lifting one wing at a time and moving head slowly back and forth.
Yellow-legged Buttonquail
Turnix tanki
Hardly bigger than a sparrow, this odd little ground bird has a disproportionately loud song. The booming hoots the female gives during the breeding season are often the easiest way to find this species in the open grassy habitats it occupies. Females are more vividly colored than males, with a bright orange breast and nape, yellow belly, white throat, and speckled gray upperparts. Males have a faded version of the same general color scheme, but have less spotting on the breast and a tan throat.
Ecuadorian Tyrannulet
Phylloscartes gualaquizae
Small, warbler-like flycatcher found in cloud forest along the east slope of the Andes in Ecuador, northern Peru, and southern Colombia. Plumage is yellow-olive with a gray crown, yellowish wingbars, white eyebrow, and black stripe through the eye. Facial pattern is not well-defined, imparting a “messy” look. Also note thin, black bill. Forages actively in the forest canopy, frequently giving a dry, sputtering trill, and is almost always encountered with mixed-species flocks.
