Jerdon's Babbler Chrysomma altirostre is a passerine bird from South Asia. Formerly placed in the Timaliidae family - hence the common name "babbler" -, the genus Chrysomma and its relatives are actually closer to the typical warblers and parrotbills in the Sylviidae (Jønsson & Fjeldså 2006).

It is classified as Vulnerable by the IUCN. The nominate subspecies from Myanmar, the Myanmar Jerdon's Babbler ( Chrysomma altirostre altirostre) seems already to be extinct. It occurred in tall-grass habitat in the floodplains of the Ayeyarwady River from Bhamo to Bago and up the Sittang River nearly to Taungoo. It was last seen in July 1941 in habitat fragments at Myitkyo, with the last specimen taken in 1914 or perhaps as late as the mid-1930s. Due to the inaccessibility of its range and consequent lack of fieldwork, it might conceivably still exist.(Collar et al. 2001, BLI 2006)

Of the Sind Jerdon's Babbler (C. a. scindicum) from the Indus basin and the Terai Jerdon's Babbler (C. a. griseigularis) of the sub-Himalayan plains, together less than 10000 mature birds are believed to remain. Its threat category VU A2c+3c (BLI 2004). This means that its population has declined by an estimated 30% and is expected to continue to do so for another decade at least. The reasons are not fully understood, but the population reduction is probably related to habitat destruction for agriculture and flood control.
