Mançurya Çalıbülbülü Horornis canturians

Warm brownish songbird of shrubby forest edges, reedbeds, and gardens. Brown above, pale below, with pale supercilium and dark eyeline. Note rufous crown. Shy and skulking, rarely straying from dense undergrowth even when singing. Usually detected by its song, a long mournful whistle followed by a quick burst of rich, bubbly notes. All but indistinguishable from Japanese Bush Warbler; averages slightly more rufous on the crown, but best identified by range and voice.
