The red-cheeked cordon-bleu or red-cheeked cordonbleu is a small passerine bird in the family Estrildidae. This estrildid finch is a resident breeding bird in drier regions of tropical Sub-Saharan Africa. Red-cheeked cordon-bleu has an estimated global extent of occurrence of 7,700,000 km

Like other members of its genus, the red-cheeked cordon-bleu is a very small finch, measuring only 12.5–13 cm (4.9–5.1 in) in length.[10] It weighs 9.9 g (0.35 oz) on average, with known extremes in wild populations ranging from 8.9–11 g (0.31–0.39 oz).[11] The adult male has uniformly brown upper parts, pale blue breast, flanks and tail and a yellow belly. There is a red patch on each cheek, but this can rarely appear orange or even yellow. Females are similar but duller, and lack the cheek spot. Immature birds are like the female, but with blue restricted to the face and throat.
