CITES Appendix II. It is protected in Thailand, but is likely extinct there. Extinctions have also likely occurred in several protected areas on Sumatra, but the species persists in Taman Negara in Peninsular Malaysia at least four in Kalimantan and several (including Taman Negara) in Peninsular Malaysia, though there are very few recent records away from Taman Negara (J. Eaton in litt. 2016). Some are being captive bred at Jurong Bird Park
Conservation Actions Proposed
Add the species to the list of protected species in Indonesia. Increase policing of bird markets, particularly in Indonesia and sanction those selling birds without closed rings. Tighten controls on imports and exports of live birds in the region. Advocate increased patrol frequency in and around protected areas supporting populations. Monitor surviving populations to provide early warning of the loss of birds and use remote camera networks to alert to poaching activity in sites with populations. Continue to monitor levels of trade in this species. Extend stronger legal protection to this (and other equally popular) cage-birds.
Location InformationUntil the latter part of the 20th century Straw-headed Bulbul was a widespread bulbul of lowland riparian areas from Tenasserim, Myanmar, south through Peninsular Thailand and Malaysia and Singapore to Sumatra, Java and Kalimantan, Indonesia, Brunei and Sabah and Sarawak (Malaysia) (BirdLife International 2001). From being common throughout its large range (southernmost Myanmar and Thailand, Peninsular Malaysia, Sumatra, Java and Borneo) in the 1950s it is now considered with some certainty to be extinct in Thailand and likely Myanmar, Java, Nias and Sipora and is likely to very close to extinction on Sumatra (Eaton et al. 2015). In Kalimantan, it is largely confined to areas furthest from human habitation, from where trappers still seemed to obtain individuals into the 2010s (Brickle et al. 2010), but even remote areas now lack the species and it has apparently been lost from all protected lowland areas (A. Miller in litt. 2018, Rentschlar et al. 2018). In Sabah the species remains present in several locations, but poaching has been reported even in Danum Valley. A population is also still present in Brunei, but numbers are unknown.
The only population that appears to be increasing is that found within Singapore, which has been present since at least the 1920s (Y. Ding Li in litt. 2018) and was estimated to contain 202 individuals in 2016 (Yong et al. 2017).
Brunei Darussalam, Indonesia, Malaysia, Myanmar, Singapore
Population InformationA revised population estimate based on an appraisal of the areas where populations are currently persisting, principally large protected areas in Malaysia and the small population in Singapore, places the number in the band 1,000-2,499 individuals, considered to represent 667-1,667 mature individuals, rounded to 600-1,700 mature individuals.
ThreatsThe quality of its songs makes it a very popular cage-bird, which has resulted in extensive trapping for both domestic and international trade. Its lack of shyness and habit of roosting and nesting in easily accessible locations has compounded its vulnerability to trapping. A single bird cost around US$20 in 1987 (Basuni and Setiyani 1989), but prices have risen to over 20 times this in 2015 (Bergin et al. 2018). Prices are complicated by the value placed on champion song birds, which compete for very large prizes at events across Java and Bali (Jepson 2008). However an average price for clearly wild-caught untrained birds are alarmingly high: in surveys across west Borneo in 2015/16 it was US$483 (A. Miller in litt. 2016), while in Java a mean of $547 was reported (Chng et al. 2015). But this continues to rise, reinforcing the evidence that scarcity of supply will not reduce demand but rather enhance it. Only three birds were found in an inventory of some bird sellers in Sumatra in 2018, two priced at $752 each and one at $902 (Chng et al. 2018). Wild-caught birds are still considered superior and that birds without closed rings far outnumbered those that possessed them, indicating a disregard for this form of trade control and a continuing lack of enforcement of illegal trade (S. Chng in litt. 2016, 2018). Bird breeding does not appear to be alleviating demand for wild-caught birds (with prices so high this is no surprise) and some breeding operations in Kalimantan visited were considered to be fronts for trading wild-caught birds (Rentschlar et al. 2018).
Despite its tolerance of secondary habitats, clearance of lowland forest along rivers has probably contributed to its decline and has certainly enabled trappers access to a far greater proportion of the species's range.
