Family Bush-warblers (Scotocercidae)

Least Concern

Yellow-bellied Warbler (Abroscopus superciliaris)


French: Bouscarle à sourcils blancs German: Bambusdickichtsänger Spanish: Mosquitero cejiblanco
Other common names: Bamboo Bush-warbler

Abrornis superciliaris


, 1859,

Tenasserim, Myanmar


Bornean subspecies schwaneri differs vocally from others and merits investigation; moreover, birds in N Borneo “dramatically distinct in vocalizations”#R from all others, (including those in rest of Borneo), and probably represent a separate species; Javan race vordermani also warrants study. Genetic and bioacoustic research needed. Ten subspecies recognized.
