Black-headed Shrike-babbler

The black-headed shrike-babbler (Pteruthius rufiventer) is a bird species traditionally placed with the Old World babblers in the family Timaliidae. However, it might be one of the few Eurasian vireos (Vireonidae). It is found in an area that ranges from eastern Nepal to northwestern Vietnam. Its natural habitat is subtropical or tropical moist montane forests. Pteruthius rufiventer is the scientific name used in the project list. (Wikipedia, general species account).

Babblers and their close allies are generally active passerines of forest, scrub or undergrowth. Many travel in pairs, family parties or mixed-species flocks while searching foliage, bark and leaf litter for invertebrates, sometimes adding fruit or seeds. Voice and social behaviour are often useful identification clues. These are family-level notes rather than Vietnam-specific breeding measurements (general babbler ecology). Regional observations can refine these broad expectations.
