The crested drongo (Dicrurus forficatus) is a passerine bird in the family Dicruridae. It is black with a bluish-green sheen, a distinctive crest on the forehead and a forked tail. There are two subspecies; D. f. forficatus is endemic to Madagascar and D. f. potior, which is larger, is found on the Comoro Islands. Its habitat is lowland forests, both dry and humid, and open savannah country. It is a common bird and the IUCN has listed it as "least concern".
In 1760 the French zoologist Mathurin Jacques Brisson included a description of the crested drongo in his Ornithologie based on a specimen collected in Madagascar. He used the French name Le grand gobe-mouche noir hupé de Madagascar and the Latin Muscicapa Madagascariensis nigra major cristata. [2] Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. [3] When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition, he added 240 species that had been previously described by Brisson. [3] One of these was the crested drongo. Linnaeus included a brief description, coined the binomial name Lanius forficatus and cited Brisson's work. [4] The specific name forficatus is Neo-Latin for "scissor-shaped". [5] This species is now placed in the genus Dicrurus that was introduced by French ornithologist Louis Pierre Vieillot in 1816. [6]
Two subspecies are recognised: [7]
The common name of drongo, now applied to all members of the family Dicruridae, was originally a Malagasy word from the Betsimisaraka dialect; more commonly it is called railovy in Malagasy. [8]
The adult male and female are almost entirely black, with a blue-green sheen. The distinctive crest consists of elongated feathers on the forehead. The forked tail is also distinctive of the adult birds. D. f. potior is larger and has broader tail feathers. [9]
The nominated race is endemic to Madagascar, and found throughout the island, and some of the larger inshore islands including Nosy-Bé. The Dicrurus forficatus potior subspecies on only found on the Comoro Islands. [9]
Its natural habitats are subtropical or tropical dry forest, subtropical or tropical moist lowland forest, and dry savanna, typically below 1,000 meters. [9]
The greater racket-tailed drongo is a medium-sized Asian bird which is distinctive in having elongated outer tail feathers with webbing restricted to the tips. They are placed along with other drongos in the family Dicruridae. They are conspicuous in the forest habitats often perching in the open and by attracting attention with a wide range of loud calls that include perfect imitations of many other birds. One hypothesis suggested is that these vocal imitations may help in the formation of mixed-species foraging flocks, a feature seen in forest bird communities where many insect feeders forage together. These drongos will sometimes steal insect prey caught or disturbed by other foragers in the flock and another idea is that vocal mimicry helps them in diverting the attention of smaller birds to aid their piracy. They are diurnal but are active well before dawn and late at dusk. Owing to their widespread distribution and distinctive regional variation, they have become iconic examples of speciation by isolation and genetic drift.
The yellow-crowned gonolek, also known as the common gonolek, is a medium-sized passerine bird in the bushshrike family. It is a common resident breeding bird in equatorial Africa from Senegal and Democratic Republic of Congo east to Ethiopia. It is a skulking bird and frequents dense undergrowth in forests and other wooded habitats. The nest is a cup structure in a bush or tree in which two eggs are laid.
The olive bee-eater or Madagascar bee-eater is a near passerine bee-eater species in the genus Merops. It is native to the southern half of Africa where it is present in Angola; Botswana; Burundi; Comoros; Democratic Republic of the Congo; Djibouti; Eritrea; Ethiopia; Kenya; Madagascar; Malawi; Mayotte; Mozambique; Namibia; Rwanda; Somalia; South Sudan; Sudan; Tanzania; Uganda; Zambia; Zimbabwe. It is a common species with a wide range so the International Union for Conservation of Nature has rated their conservation status as "least concern".
The Namaqua dove is a small pigeon. It is the only species in the genus Oena. It is found over much of Sub-Saharan Africa as well as Arabia and Madagascar.
The black-crested antshrike is a passerine bird in the antbird family. It is a resident breeder in tropical South America in Trinidad, Colombia, Venezuela, the Guianas, northern Brazil and northeastern Peru. It is unclear whether the species also occurs south of the Amazon in Brazil.
The hair-crested drongo is an Asian bird of the family Dicruridae. This species was formerly considered conspecific with Dicrurus bracteatus, for which the name "spangled drongo" – formerly used for both – is now usually reserved. Some authorities include the Sumatran drongo in D. hottentottus as subspecies.
The red fody, also known as the Madagascar fody in Madagascar, red cardinal fody in Mauritius, or common fody, is a small bird native to Madagascar and introduced to various other islands in the Indian Ocean. It is a common bird within its restricted range, and the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".
The black-faced munia is a species of estrildid finch found in Indonesia and East Timor. It occurs in a wide range of habitats including artificial landscapes, forest, grassland and savannah. It was first described by the Swedish naturalist Carl Linnaeus in the twelfth edition of his Systema Naturae in 1766. The IUCN has evaluated the status of this bird as being of least concern.
The long-billed bernieria, formerly known as long-billed greenbul and sometimes as common tetraka or long-billed tetraka, is a songbird species endemic to Madagascar. It is the only species placed in the genus Bernieria. Its natural habitat is subtropical or tropical moist lowland forests.
The Madagascar blue pigeon or Madagascan blue pigeon is a species of bird in the family Columbidae. The species is closely related to the other two extant species of blue pigeon, the Comoros blue pigeon and the Seychelles blue pigeon. It is endemic to northern and eastern Madagascar.
The Madagascar green pigeon is a species of bird in the family Columbidae. It is found in Madagascar, Comoros, and Mayotte. The taxon griveaudi, by most authorities considered a subspecies of the Madagascan green pigeon, is sometimes considered a separate species, the Comoros green pigeon. Its natural habitats are subtropical or tropical dry forest and subtropical or tropical moist lowland forest.
The red-tailed vanga is a species of bird in the family Vangidae. It is endemic to Madagascar.
The balicassiao is a species of passerine bird in the family Dicruridae. It is endemic to the Philippines.
The Caribbean elaenia is a species of bird in the family Tyrannidae found in the West Indies and parts of Central America. Its natural habitats are tropical and subtropical dry broadleaf forest, subtropical or tropical moist lowland forest, and heavily degraded former forest.
The rufous vanga is a species of bird in the family Vangidae. It is monotypic within the genus Schetba. It is endemic to Madagascar, where its natural habitats are subtropical or tropical dry forest and subtropical or tropical moist lowland forest.
The fulvous-crested tanager is a species of bird in the family Thraupidae, the tanagers.
The Malagasy paradise flycatcher is a species of bird in the family Monarchidae. It is found in Comoros, Madagascar, and Mayotte. Its natural habitats are subtropical or tropical dry forest and subtropical or tropical moist lowland forest.
The hook-billed vanga is a species of bird in the family Vangidae. It is endemic to Madagascar. Its natural habitats are subtropical or tropical dry forest, subtropical or tropical moist lowland forest, and subtropical or tropical moist montane forest.
