Neomixis flavoviridis

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).

Description

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.

Ecology and behaviour

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.

Distribution and habitat

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.
