charlotte's bulbul Iole charlottae

Dull brown bulbul with a long bill and pale eyes. Endemic to Borneo, where it inhabits lowland forests and forest edges. Fairly adaptable, often occurring in degraded and regenerating wooded habitats. May be easily confused with other plain bulbuls; note this species’ pale eyes, unmarked yellowish-suffused underparts, and clean white throat. Not as social as some other bulbuls, typically moving through the middle and upper levels of forest individually or in pairs. Gives a somewhat hoarse “jeet!” and a nasal “jee-wit!”, and a repetitive series: “wee-jy-jy-jy!”
