The straw-headed bulbul is a species of songbird in the bulbul family, Pycnonotidae. Wikipedia
Scientific name: Pycnonotus zeylanicus
The straw-headed bulbul is prized for its singing ability and is a highly sought-after species by bird enthusiasts in Southeast Asia, especially Indonesia. This trade is causing population reductions across the species’ range and is a major barrier to its conservation. Trapping has been facilitated in recent years by the spread of logging roads across its forest habitat. Due to this, the straw-headed bulbul was uplisted from endangered to critically endangered on the IUCN Red List in 2018

It’s resident in Singapore, and it’s quite common to hear their singing, but a bit difficult to spot them, mostly found in Bukit Batok – Bukit Timah Nature Reserve.
