The wedge-tailed jery (Hartertula flavoviridis) is a small bird endemic to the east of Madagascar. The species has been the cause of some taxonomic confusion, it was originally placed with the jeries in the genus Neomixis (Cisticolidae) before being placed in its own monotypic genus Hartertula, but still considered close to Neomixis. Recent research indicates it is part of an endemic Malagasy radiation currently known as the Malagasy warblers (Cibois et al. 2001).
The wedge-tailed jery is a small, slender warbler-like bird between 12–13 cm long and weighing around 10 g. The plumage is bright yellow before and olive on the crown, wing and back. The eye has a pale white ring and is crossed with a pale supercilium. There is no sexual dimorphism in the plumage of adults, and juvenile birds have similar plumage as well.
The call, sung repetitively during foraging, is a nasal tsee zeezeezeezeezeezee. In the rainforest they forage in the low understory, gleaning insects from the undersides of leaves and branches, often hanging upside down to do so. They are also accomplished at extracting insects from clumps of leaves and spider web at the ends of branches. They forage in small groups and will also join mixed-species feeding flocks. They nest in small grass nests shaped like balls suspended between 1–2 m above the ground. Little is known about their breeding behaviour but they are known to have clutch sizes of two eggs.
Wedge-tailed jeries inhabit dense stands of rainforest in the east of Madagascar. They are most commonly found in the mid-altitude rainforests between 500–1400 m, and are rarer at lower altitudes and absent above 2300 m.
The wedge-tailed jery is currently listed as near-threatened by the IUCN. [1] The species is confined to mid-altitude rainforest, but this is currently the least threatened forest habitat in Madagascar. There is some danger of habitat loss, and the species is not common anywhere in its range.
Old World warblers are a large group of birds formerly grouped together in the bird family Sylviidae. They are not closely related to the New World warblers. The family held over 400 species in over 70 genera, and were the source of much taxonomic confusion. Two families were split out initially, the cisticolas into Cisticolidae and the kinglets into Regulidae. In the past ten years they have been the subject of much research and many species are now placed into other families, including the Acrocephalidae, Cettiidae, Phylloscopidae, and Megaluridae. In addition some species have been moved into existing families or have not yet had their placement fully resolved. A smaller number of warblers, together with some babblers formerly placed in the family Timaliidae and the parrotbills, are retained in a much smaller family Sylviidae.
The family Vangidae comprises a group of often shrike-like medium-sized birds distributed from Asia to Africa, including the vangas of Madagascar to which the family owes its name. Many species in this family were previously classified elsewhere in other families. Recent molecular techniques made it possible to assign these species to Vangidae, thereby solving several taxonomic enigmas. The family contains 40 species divided into 21 genera.
The family Cisticolidae is a group of about 160 warblers, small passerine birds found mainly in warmer southern regions of the Old World. They were formerly included within the Old World warbler family Sylviidae.
The fairy flycatcher or fairy warbler is a small passerine bird. Formerly placed in the Old World flycatcher family, Muscicapidae, it is now separated with some other "odd flycatchers" as the new family Stenostiridae. It is the only member of the genus Stenostira.
The tetrakas and allies are a newly validated family of songbirds. They were formally named Bernieridae in 2010. The family currently consists of eleven species of small forest birds. These birds are all endemic to Madagascar.
Appert's tetraka formerly known as Appert's greenbul is a small passerine bird endemic to the south-west of Madagascar. The species was only described in 1972, and has been the subject of considerable taxonomic confusion. It was initially placed in the greenbul genus Phyllastrephus, and later with the Old World warblers in the genus Bernieria. Recent research indicates it is part of an endemic Malagasy radiation currently known as the Malagasy warblers.
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 white-throated oxylabes is a species of passerine bird that is endemic to Madagascar. It is the only species placed in the genus Oxylabes. Formerly considered as a member of the Old World warbler family Sylviidae, it has been moved to the family Bernieridae — the Malagasy warblers. Its natural habitat is subtropical or tropical moist lowland forests.
The Malagasy coucal or Madagascar coucal is a species of cuckoo in the family Cuculidae. It is found in Madagascar and in the Seychelles, where it occurs on Aldabra and was formerly present on Assumption Island and Cosmoledo. Its natural habitats are dense vegetation in subtropical or tropical moist lowland forests, mangrove forests, rough grassland, marshes and reedbeds.
Coquerel's coua is a species of cuckoo in the family Cuculidae. It is endemic to Madagascar. Its habitat is subtropical or tropical dry forests. It was named in 1867 by the French naturalist Alfred Grandidier in honor of the French navy surgeon and naturalist Charles Coquerel.
The Madagascar scops owl, also known as the Malagasy scops owl or Rainforest scops owl, is a species of owl in the family Strigidae. It is found throughout Madagascar, now that is has recently been lumped with the Torotoroka scops owl, with which it was long considered a separate species from. The nominate O. r. rutilus is referred to as Rainforest scops owl.
The whistling warbler is a species of bird in the New World warbler family. It is monotypic within the genus Catharopeza. It has a dark back that fades into a lighter gradient going towards the chest. It also has a dark head, a dark strip on the breast, and a light orbital. Both male and female have the same plumage. It is endemic to the island of Saint Vincent in the Lesser Antilles. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest. It is threatened by habitat loss. This habitat loss is due to volcanic activity and deforestation. Whistling warblers have cup-shaped nests, and spotted eggs. Their diet primarily consists of insects.
The Madagascar magpie-robin is a species of chat in the Old World flycatcher family, Muscicapidae.
The grey-capped warbler is a species of bird in the family Cisticolidae. It is monotypic in the genus Eminia. The grey-capped warbler is found in Burundi, Democratic Republic of the Congo, Kenya, Rwanda, South Sudan, Tanzania, and Uganda. It is a large, chunky, thin-tailed-warbler with a distinctive grey cap, a black band around its head, and a chestnut throat wrapping its neck. Grey-capped warblers maintain a diet of insects and other invertebrates, including caterpillars, moths, grasshoppers, and mantids.
The sickle-billed vanga is a species of bird in the vanga family Vangidae. It is monotypic within the genus Falculea. It is endemic to Madagascar. Its natural habitats are tropical dry forests and tropical dry shrubland.
The stripe-throated jery is a species of bird in the family Cisticolidae. It is endemic to Madagascar.
Neomixis is a genus of small forest birds that are endemic to Madagascar.
Newtonia is a genus of passerine birds containing four to five species. They were formerly classified in the Old World warbler family Sylviidae or Old World flycatcher family Muscicapidae but have recently been shown to belong to the vanga family Vangidae. They are endemic to Madagascar where they occur in forest or scrubland. They forage in pairs for insects, often joining mixed-species feeding flocks.
Zahamena National Park is a national park of Madagascar. Established in 1997, it covers an area of 423 square kilometres (163.32 sq mi) out of a total protected area of 643 square kilometres (248.26 sq mi). It is part of a UNESCO World Heritage Site, Rainforests of the Atsinanana, inscribed in 2007 and consisting of 13 specific areas located within eight national parks in the eastern part of Madagascar. In 2001, Bird Life International assessed avifauna of 112 species of which 67 species are exclusively endemic to Madagascar.
Kalambatritra Special Reserve is a wildlife reserve in southern Madagascar. It is to the north of Andohahela National Park, south-west of the Manombo Special Reserve and contains many endemic species, including forty-five endemic bird species.
