Mangrov Islıkçısı Pachycephala cinerea

Drab small bird with brownish-gray upperparts and white underparts. Resides primarily in mangrove forest, but can also be found in other well-vegetated adjacent habitat types. Overall lack of prominent markings distinguishes it from other mangrove species within its range. Song varies; Indian birds give songs containing long ringing whistles, while Southeast Asian birds give somewhat more complex whistled phrases.
