Rufous-backed Dwarf-Kingfisher
Ceyx rufidorsa
Tiny, unbelievably cute kingfisher: a luminous ball of pink, orange, yellow, and varying amounts of blue and purple. Brightly-colored back distinguishes this species from closely related Black-backed Dwarf-Kingfisher. Forages in shaded patches of dense vegetation, in mangroves, overgrown edge, or deep lowland and foothill forest. Can be near or away from water; when near water, often near shallow forest streams and small pools. Gives high squeaks and thin whistles, often as paired notes.
分类信息
The rufous-backed dwarf kingfisher was formally described in 1847 by the English naturalist Hugh Edwin Strickland under the current binomial name Ceyx rufidorsa. He specified the type locality as Malacca at the southern end of the Malay Peninsula. The specific epithet combines Latin rufus meaning "rufous" with dorsus meaning "back".<p>The rufous-backed dwarf kingfisher was formerly considered to be a colour morph of the black-backed dwarf kingfisher (Ceyx erithaca). The two species complex was known as the "oriental dwarf kingfisher". Molecular genetic studies have shown that Ceyx rufidorsa is a distinct taxon and that the polymorphism is the result of ancient introgression in which some genes from Ceyx erithaca were transferred to Ceyx rufidorsa around 140,000 years ago.<p>Five subspecies are recognised:

Black-and-gold Tanager
Bangsia melanochlamys
Colorful and rather chunky tanager with a stout bill. It is endemic to Colombia, where it inhabits cloud forest in the western Andes as well as the northern end of the central Andes. Plumage is black with an orange breast, yellow belly, and blue shoulders. Similar to Golden-chested Tanager, but yellow on underparts is much more extensive. Usually seen in middle to upper levels of the forest, sometimes with mixed species flocks. Song, often given from an exposed perch, is a rasping “pit-zhee” that may be given several times in quick succession.
Green-backed White-eye
Zosterops xanthochroa
A classic small greenish-yellow white-eye species with bold white eye-rings. Common in more humid habitats throughout New Caledonia; mostly replaced by Silvereye in drier and more disturbed areas, though the two can be found together. Green-backed is plainer overall than Silverye, without any contrasting plumage apart from the eyering. Has a typical white-eye vocal repertoire, with a high-pitched wheezy warbling song and high-pitched piercing quavering call notes.
Shining-blue Kingfisher
Alcedo quadribrachys
Compact kingfisher with a dark blue back and rufous underparts. The color of the back varies geographically, and can be purple-blue or paler blue. Found along forested streams and rivers and in mangroves. Secretive, solitary, and generally uncommon. Call is a high-pitched “seet.” Larger than Malachite Kingfisher, with a black bill. Similar to juvenile Malachite, which has a dark bill, but Shining-blue has a dark face without any orange.
