Newtonia amphichroa
The Dark Newtonia, *Newtonia amphichroa*, is a small, unobtrusive passerine endemic to the humid forests of eastern Madagascar. Measuring approximately 12 cm (4.7 in) in length and weighing around 9-12 grams (0.3-0.4 oz), this species exhibits a rather drab yet distinct plumage. Its upperparts are a uniform dark olive-brown, contrasting subtly with slightly paler, greyish-brown underparts, often with a faint olive wash. A key field mark distinguishing it from other Newtonias is its overall da...
Found primarily in humid evergreen forests, particularly mid-altitude and montane rainforests, from sea level up to around 2,000 meters.
Primarily insectivorous, feeding on small invertebrates such as beetles, caterpillars, spiders, and other arthropods, which they glean from foliage and bark.
Dark Newtonias are active, diurnal birds, typically observed foraging individually or in pairs, though they frequently join mixed-species foraging flocks, particularly those led by Vangas or Cuckoo-Rollers. They employ an active gleaning foraging strategy, moving rapidly through the understory an...
The Dark Newtonia is endemic to eastern Madagascar, where it is widely distributed along the humid forest belt. Its breeding range encompasses the full extent of this forested region, from the northern tip of the eastern escarpment down to the southeastern parts of the island. Specific locales in...
Least Concern
- The Dark Newtonia is one of four species in the genus Newtonia, all of which are endemic to Madagascar. - Despite its drab appearance, its vocalizations are quite distinctive and a key way to identify it in dense forest. - It is a common participant in mixed-species foraging flocks in Malagasy ...
