Southern Asia from India east to Thailand, Malaysia, Singapore (where it is a rare non-breeding visitor) to Indonesia and Timor.


Taxonomy complex, with different authorities recognising different species. They may be divided as follows: agile and zeylonicum as "Agile Flowerpecker" (D. agile); atjehense, finschi, modestum and pallescens as "Modest Flowerpecker" (D. modestum); obsoletum and tinctum as "Tenggara Flowerpecker" (D. obsoletum); and aeruginosum, affine and striatissimum as "Striped Flowerpecker" (D. aeruginosum) [5]. The IOC currently recognises Striped Flowerpecker [6]. The treatment here follows [1].
