Archbold's Newtonia

Overview

Archbold's newtonia (Newtonia archboldi) is a small, short-winged bird in the family Vangidae, endemic to Madagascar. The species is assessed as Least Concern by the IUCN and is fairly common throughout its range, despite experiencing habitat logging.

Identification

• Size: Small and long-legged, measuring approximately 12 cm in length with a short and slender bill.
• Plumage: Greyish brown upperparts and tail, a rufous forecrown, buffy white throat and belly, and cinnamon buff breast and flanks.
• Markings: Conspicuous dark rufous eye-ring, black bill, and pale yellow eyes; sexually monomorphic with no distinct breeding plumage.
• Song: Distinctive variable warbles composed of 4-5 syllables, such as 'tee-too tekhew' or 'chichichich wit-tee tew', often sung from concealed perches.

Habitat

This species is restricted to southern Madagascar, occurring primarily near the coast but also farther inland in two disjunct populations. It inhabits subtropical or tropical dry forests, including spiny forests composed of Didiereaceae, Euphorbia, and baobabs, as well as neighbouring scrubby vegetation. It typically resides below 100 m but can reach up to 600 m on rocky massifs and is non-migratory.

Diet

Archbold's newtonia is an insectivore that feeds almost entirely on arthropods, including spiders, beetles, true bugs, termites, caterpillars, and grasshoppers. Foraging occurs individually in the understory and midstory, where the bird actively hops through branches to glean prey from twigs, foliage, bark, or occasionally the ground.

Did you know?

The nests of Archbold's newtonia are open cup structures that are not attached to any surface; instead, they are supported solely by four thin twigs, two of which pass through the nest and two of which are attached using cobwebs.
