Genera

Dicaeum
Prionochilus

The flowerpeckers are a family, Dicaeidae, of passerine birds. The family comprises two genera, Dicaeum and Prionochilus , with 50 species in total. The family has sometimes been included in an enlarged sunbird family Nectariniidae. The berrypeckers of the family Melanocharitidae and the painted berrypeckers, Paramythiidae, were once lumped into this family as well. The family is distributed through tropical southern Asia and Australasia from India east to the Philippines and south to Australia. The family has a wide range occupying a wide range of environments from sea level to montane habitats. Some species, such as the mistletoebird of Australia, are recorded as being highly nomadic over parts of their range. [1]

There is little variation in structure between species in the family although many have distinctive and colourful plumage. Flowerpeckers are stout birds, with short necks and legs. These are small birds ranging from the 10-cm, 5.7-gram pygmy flowerpecker to the 18-cm, 12-gram mottled flowerpecker. Flowerpeckers have short tails, short thick curved bills and tubular tongues. The latter features reflect the importance of nectar in the diet of many species. They also have digestive systems that have evolved to deal efficiently with mistletoe berries. [1] They are often dull in colour, although in several species the males have brightly patterned crimson or glossy-black plumage.

Nectar forms part of the diet, although they also take berries, spiders and insects. [3] Mistletoes of 21 species in 12 genera have been found to be part of the diet of flowerpeckers, and it is thought that all species have adaptations to eat these berries and dispose of them quickly. Flowerpeckers may occur in mixed-species feeding flocks with sunbirds and white-eyes, as well as other species of flowerpecker.

The breeding biology of the flowerpeckers has been little studied. [1] In the species where data has been collected they apparently form monogamous pairs for breeding, but the division of labour varies; in scarlet-breasted flowerpeckers both parents participate in all aspects of nest building, incubation and chick rearing, but in the mistletoebird the female undertakes the first two tasks alone. Flowerpeckers lay 1–4 eggs, typically in a purse-like nest of plant fibres, suspended from a small tree or shrub. Recorded incubation times are scarce, but range from 10–12 days, with fledging occurring after 15 days.

The two genera in the family are separated on the basis of the length of the outermost primary which is elongated in Prionochilus and reduced in most Dicaeum species although D. melanozanthum is an exception with an elongated outer primary. Molecular phylogeny studies, however, suggest that some Dicaeum are closer to species traditionally in Prionochilus and that generic placements across the family may need to be revised. [4]

The majority of flowerpeckers are resilient in their habits and are not threatened by human activities. [1] Five species are considered to be near threatened by the IUCN, two are listed as vulnerable and one, the Cebu flowerpecker, is listed as critically endangered. The status of the enigmatic spectacled flowerpecker is unknown. Habitat loss is the cause of the declines of these species.

Sunbirds and spiderhunters make up the family Nectariniidae of passerine birds. They are small, slender passerines from the Old World, usually with downward-curved bills. Many are brightly coloured, often with iridescent feathers, particularly in the males. Many species also have especially long tail feathers. Their range extends through most of Africa to the Middle East, South Asia, South-east Asia and southern China, to Indonesia, New Guinea and northern Australia. Species diversity is highest in equatorial regions.

The Nilgiri flowerpecker is a tiny bird in the flowerpecker family. Formerly a subspecies of what used to be termed as the plain flowerpecker although that name is now reserved for Dicaeum minullum. Like others of the group, it feeds predominantly on nectar and fruits. They forage within the canopy of forests and are found in India. They are non-migratory and the widespread distribution range includes several populations that are non-overlapping and morphologically distinct, some of which are recognized as full species. They are important pollinators and dispersers of mistletoes in forests.

The pale-billed flowerpecker or Tickell's flowerpecker is a tiny bird that feeds on nectar and berries, found in India, Sri Lanka, Bangladesh and western Myanmar. The bird is common especially in urban gardens with berry bearing trees. They have a rapid chipping call and the pinkish curved beak separates it from other species in the region.

<span class="mw-page-title-main">Painted berrypecker</span> Family of birds

The painted berrypeckers, Paramythiidae, are a very small bird family restricted to the mountain forests of New Guinea. The family comprises three species in two genera: the tit berrypecker in Oreocharis, and the eastern crested berrypecker and western crested berrypecker in Paramythia. These are colourful medium-sized birds which feed on fruit and some insects. These species were formerly included in the Dicaeidae, but DNA–DNA hybridization studies showed these species were related to each other but distinct from the flowerpeckers. Some sources group painted berrypeckers as two genera belonging to the berrypecker family Melanocharitidae.

The female is dull coloured.

<span class="mw-page-title-main">Black-sided flowerpecker</span> Species of bird

The black-sided flowerpecker, also known as the Bornean flowerpecker, is a species of bird in the family Dicaeidae. It is endemic to the island of Borneo, where it is found in the mountains, primarily above 1,000 m (3,300 ft) in elevation. The species is sexually dimorphic. The male has glossy blue-black upperparts, with a scarlet throat and breast, a dark grey upper belly, olive flanks, a white lower belly, and a buffy vent and undertail coverts. The female is olive-green above and greyish below, with buffy flanks and a whitish throat. It inhabits a range of forest habitats, including primary and secondary montane forest, kerangas forest, and scrub, and is also occasionally found in gardens. It feeds primarily on small fruits—particularly mistletoe berries—as well as seeds, nectar, and various invertebrates. It builds a nest of moss, camouflaged on the outside with lichens and lined with the pith of tree ferns. The International Union for Conservation of Nature rates it as a species of least concern. Though its numbers have not been quantified, the black-sided flowerpecker is said to be common throughout much of its range, and any declines are not thought to be precipitous. However, destruction of forest for palm plantations may impact it.

<i>Prionochilus</i> Genus of birds

Prionochilus is one of two genera flowerpecker that make up the family Dicaeidae. The genus differs from the other flowerpecker genus, Dicaeum in having ten long primary feathers in the wing and in the character of its calls. A study comparing the calls of the two genera suggested that Prionochilus is basal to Dicaeum. The genus contains six species, in contrast to the 44 species in the genus Dicaeum. They have a more restricted distribution than Dicaeum, occurring in the Philippines, Borneo, Sumatra, Java and the Malay Peninsula. The name Prionochilus is derived from the Greek prion for saw, and kheilos for lip, referring to the minute serrations along the edge of the bill.
