The yellow-bellied gerygone (Gerygone chrysogaster) is a species of bird in the family Acanthizidae. The Yellow-Bellied Gerygone is native to New Guinea, typically found in subtropical or tropical moist lowlands forest. Shown to have least concern about population with it being very common, but is currently decreasing in population throughout New Guinea. The population as a whole is still unknown.
The Yellow-Bellied Gerygone is widespread throughout New Guinea, including Aru Island, Yapen Island, and West Papuan Island. They like moist environments so therefore, they will forage in lowlands and forest. Usually the Yellow-Bellied Gerygone don’t migrate during seasonal change, but rarely will migrate 760 miles in hill forest to Tabubil, New Guinea.
The Yellow-Bellied Gerygone is 10cm with brownish-olive color with a white belly. The male and female are identical and would need proper hands on examination when identifying the sex. During the breeding season, typically August-September and February- May, the females have a poor clutch size with the record being 3 eggs.The yellow-bellied gerygone also has a life span going up to almost three years....

GBIF citizen-science records
It is estimated from how often the Yellow-bellied Gerygone is recorded against all the birds logged in Raja Ampat (95 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.
