The dark newtonia (Newtonia amphichroa) is a species of bird in the family Vangidae. It is endemic to northeastern Madagascar. Its natural habitat is subtropical or tropical moist lowland forests. The dark newtonia was formally described in 1891 by the German ornithologist Anton Reichenow under the current binomial name Newtonia amphichroa based on a specimen collected in southern Madagascar. The specific epithet combines the Ancient Greek αμφι/amphi meaning "on all sides" with χροα/khroa, χροας/khroas meaning "appearance" or "colour".

Rare
Under 5% of wildlife watchers report a Dark Newtonia sighting in Mantadia National Park on a given day, based on 21 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 79th most-seen of the 98 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
July and November
In those months about 10% of wildlife watchers report a Dark Newtonia in Mantadia National Park on a given day, against under 5% in May–June, August–October and December, the lowest months. January to April have too few records to rate.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Dark Newtonia sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
2nd of 2
Of the 2 parks where we can rate Dark Newtonia sightings, Mantadia National Park ranks 2nd at under 5%. The best odds are in Ranomafana National Park (Madagascar, about 30%).
GBIF citizen-science records
It is estimated from how often the Dark Newtonia is recorded against all the birds logged in Mantadia National Park (21 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
