Thamnornis chloropetoides
The Thamnornis, *Thamnornis chloropetoides*, is a charismatic member of the Malagasy warbler family (Bernieridae), endemic to the arid spiny forests of southwestern Madagascar. This medium-sized passerine measures approximately 14-15 cm in length and weighs around 13-17 grams, characterized by olive-green upperparts that seamlessly blend into its dense habitat. Its underparts are a pale yellow to whitish, providing a subtle contrast, while a distinctive pale supercilium sharply contrasts with...
Exclusively found in the xerophytic spiny forest and adjacent dry deciduous forest of southwestern Madagascar, typically at elevations below 500 meters.
Primarily insectivorous, feeding on a wide variety of insects and their larvae, which it actively gleans from foliage and bark.
The Thamnornis is a diurnal and highly active bird, though often secretive, preferring to forage within the dense understory and mid-level vegetation. It typically moves in pairs or small family groups, occasionally joining mixed-species flocks alongside other Malagasy endemics. Foraging involves...
The Thamnornis is strictly endemic to the arid spiny forest ecoregion of southwestern Madagascar, a unique biome characterized by drought-adapted thorny plants. Its distribution is concentrated in a relatively narrow band extending from the southwestern coast inland, roughly between the Mangoky a...
