Van Hasselt's Sunbird
Leptocoma brasiliana
Attractive medium-sized sunbird of lowland forests, from coastal scrub forests to inland evergreen forests. Male is black with an iridescent pink-red throat, a red belly, and a glistening blue-green crown. Female is extensively yellowish with a pale vent and a thin dark line through the eye. Purple-throated Sunbird is essentially identical, but ranges do not overlap. Female Plain-throated Sunbird can be similar, but is straighter-billed, with a darker head, and a faint pale ring around the eye. Song, often given from an exposed perch, consists of squeaky rising whistles and chip notes.

Van Hasselt's sunbird was described and illustrated in 1760 by the French zoologist Mathurin Jacques Brisson . He introduced the French name "Le grimpereau violet de Brésil" in the mistakenly belief that his specimen had been collected in Brazil. [ 2 ] When the German naturalist Johann Friedrich Gmelin revised and expanded Carl Linnaeus 's Systema Naturae in 1788 he included Van Hasselt's sunbird using Brisson's account. He placed it with the tree-creepers in the genus Certhia and coined the binomial name Certhia brasiliana . He specified the location as Brazil and cited Brisson's book. [ 3 ] In 1825 the Dutch zoologist Coenraad Jacob Temminck described and illustrated Van Hasselt's sunbird based on a specimen that had been collected on the island of Java by Johan Conrad van Hasselt . Temminck coined the binomial name Nectarinia hasseltii , choosing the specific epithet to honour the collector. Under the rules of the International Commission on Zoological Nomenclature Gmelin's epithet has priority and Temminck's name is a junior synonym . [ 4 ] [ 5 ] The type location has been redesignated as Java. [ 6 ] Van Hasselt's sunbird is now one of six species placed in the genus Leptocoma that was introduced in 1850 by the German ornithologist Jean Cabanis . [ 7 ] The species was formerly considered conspecific with the purple-throated sunbird ( Leptocoma sperata ). [ 7 ] [ 8 ] Five subspecies are recognised: [ 7 ] In 1939, a group of bird lovers in Hawaii known as the Hui Manu released 28 of these birds on various parts of the leeward side of Oahu in Hawaii in an attempt to get them to become established there; none appeared have succeeded.

Violet-backed Hyliota
Hyliota violacea
Rather generic-looking mid-sized bird with a dark back and pale underparts. In good light, the upperparts show purple iridescence. Can show a small white patch at the top of the closed wing. Males are pale buff below, while females are orange. Found in humid forest, mostly around clearings and edge. Frequently joins mixed-species feeding flocks. Gives a short song of sweet whistles and a dry “tik” call, usually in flight. Distinguished from other hyliotas by the lack of large white patches in the wings.
Blue-backed Manakin
Chiroxiphia pareola
Small bird of riverine and gallery forests in both forest and savanna regions; generally inconspicuous when not displaying. Adult male is distinctive with black body, sky-blue back, and red or yellow crown patch; both sexes have orange legs. Female is similar to White-bearded Manakin, but has somewhat slimmer shape and longer tail. Inhabits forest understory but may ascend to canopy, especially when displaying. Feeds on fruit like other manakins and may be seen at fruiting shrubs and trees. Often detected by loud, single call note; males produce a variety of bizarre sounds in coordinated group display.
Malabar Whistling-Thrush
Myophonus horsfieldii
Deep blue ground-dweller with shining forehead and shoulder patches; belly can appear mottled blue-and-black in the right lighting. Inhabits foothills and montane forests, where it sticks closely to water, especially rocky streams and smaller rivers with overhanging vegetation and rocky ledges. Song is an eerie and human-like series of variable, deliberate-sounding whistles. Call is a high thin “tseeeeee.”
