The bold-striped tit-babbler (Mixornis bornensis) is a species of Old World babbler found in Southeast Asia. The bold-striped tit-babbler has a distinctive yellowish supercilium and rufous crown. The throat is yellowish with brown streaks.
Call is a loud repeated chonk-chonk-chonk-chonk-chonk somewhat reminiscent of a common tailorbird. The bold-striped tit-babbler is found in Borneo and Java. Bold-striped tit-babblers forage in small flocks and creep and clamber in low vegetation. They breed in the pre-monsoon season from February to July and build a loose ball-shaped nest made from grasses and leaves. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Bold-striped Tit-Babbler is recorded against all the birds logged in Sepilok (70 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.
