The yellow-bellied sunbird-asity (Neodrepanis hypoxantha) is a small species of passerine bird from the asity family. The male has black upper parts with a bluish sheen and yellow underparts, and is sometimes known simply as the yellow-bellied asity. It is found only in montane rainforests of Madagascar where it feeds on nectar that it sips from flowers, defending a good nectar source from other nectar-feeding birds. It is listed by the International Union for Conservation of Nature as "vulnerable" due to the diminution and fragmentation of its forest habitat.
The plumage of male yellow-bellied sunbird-asities is very bright, with clean yellow undersides and dark black upper sides with an iridescent blue sheen; the females are duller. The eye is surrounded by a bright blue wattle which derives its colour, like the rest of the asities, from bundles of collagen. The bill is long and decurved, as it is adapted for nectar feeding.
This species is endemic to montane forest above 1600 m on the island of Madagascar. Yellow-bellied sunbird-asities are active nectar feeders. They will aggressively defend a nectar source from rivals of the same species as well... Wikipedia →

Rare
Under 5% of wildlife watchers report a Yellow-bellied Asity sighting in Ranomafana National Park on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 94th most-seen of the 102 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Yellow-bellied Asity in Ranomafana National Park on a given day, so our monthly data shows no clear season. January and June have too few records to rate.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Yellow-bellied Asity sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Ranomafana National Park, in our data
Ranomafana National Park is the only park on Wallace's Line with enough records to rate Yellow-bellied Asity sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Yellow-bellied Asity is recorded against all the birds logged in Ranomafana National Park (12 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.
