Зерноїд чорнощокий Sporophila nigricollis

Male is a fairly distinctive seedeater with yellow belly (sometimes very pale), dark breast and face, and brownish-olive back. Often shows some smudgy dark marks down the flanks. Bill is pale silvery. Female seedeaters are extremely difficult to identify; Yellow-bellied tends to look warmer with yellowish tones on underparts, but many are best left unidentified unless accompanied by a male. Most often found in flocks or pairs in open grassy habitats, sometimes near the edge of forest but also in agricultural areas.
