Cinnamon-breasted Bunting
Emberiza tahapisi
They weigh between 11.6 and 21 grams with a length of 13–15 centimeters. Although plumage differs between juveniles, males, and females, cinnamon-breasted buntings can be identified by their striped head and cinnamon brown underparts. Males have black and white stripes whereas the female stripes are less dark and browner in color. The throat patch is uniformly black on males but smaller, grayish, and densely blotched on females. Juveniles are similar to females but with buffier head stripes and a paler, browner throat.

Little Bunting
Emberiza pusilla
This is a small bunting, measuring only 12–14 cm (4.7–5.5 in) in length. It has white underparts with dark streaking on the breast and sides. With its chestnut face and white malar stripe, it resembles a small female reed bunting, but has black crown stripes, a white eye-ring, and a fine dark border to the rear of its chestnut cheeks. The sexes are similar. The call is a distinctive zik, and the song is a rolling siroo-sir-sir-siroo.
