Chestnut-eared Bunting
Emberiza fucata
It is 15 to 16 cm in length. The plumage is mostly brown with dark streaks. The male has a grey crown and nape with dark streaks, chestnut ear-coverts and bands of black and chestnut across the breast. There is a rufous patch on the shoulders and the rump is also rufous. Females are similar to the males but duller with a less distinct head and breast pattern. First-winter birds are plainer but show warm brown ear-coverts and have an obvious ring around the eye. Its voice is similar to the rustic bunting but quieter.

Pallas's Reed Bunting
Emberiza pallasi
Pallas's reed bunting is a small passerine bird, similar to a small reed bunting and possesses a small granivore-type bill. The male has a black head and throat, a white neck collar and underparts, and a heavily streaked grey back (the reed bunting has a browner back). The female is much duller, with a streaked brown head, and is less streaked below than the female reed bunting. The song of the male is a repetitive sherp.
