白頂鵐 Emberiza stewarti

Male’s elegant black-and-white facial pattern is unique. Female is plain, streaky brown all over with faint white eye-ring, a weak hint of the male’s facial pattern, and a small white spot on the “ears”. Breeds in rocky gullies, valleys, and hillsides at middle to upper elevations; winters at lower altitudes, in fields, scrubland, and open dry forest. Song is a series of twanging buzzy pulses: “TZI-TZI-TZI-TZI-TZI.”
