Flowerpecker
The flowerpeckers are a family, Dicaeidae, of passerine birds. The family comprises two genera, "Prionochilus" and "Dicaeum", with 48 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. The enigmatic ‘Spectacled Flowerpecker’—a probable new bird species from the island of Borneo—was first sighted in the Danum Valley of Sabah, Malaysia in 2009.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. 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. 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. 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 incubations 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. The majority of flowerpeckers are resilient in their habits and are not threatened by human activities. 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. Carballo-Ortiz, M., Ragai, R., Dahlan, N., & Edwards, D. (2019).
