Though this species are native to the Lesser Sunda Islands, the chestnut-backed thrush are somewhat common in most traditional bird markets in Java, attributed to the species being succesfully bred and farmed in many Indonesian songbird farms.
Thank you for that bit of information. I know very little about Asian aviculture so I didn't realize that several of the Indonesian songbirds were being captive bred on a commercial scale! I think I'm glad to hear that so long as it takes pressure off of the wild populations and doesn't serve as a pathway for illegal smuggling (laundering wild-caught birds through facilities that purport to be captive breeding facilities.
