Stripe-tailed Yellow-Finch Sicalis citrina

Small yellow finch with a short bill found in savanna, grasslands, and other open habitats. Note the white patch under the tail, which can be difficult to see. Males are mostly bright yellow with an olive wash on the head and breast with an olive-brown streaky back. Females are yellowish-brown above and pale yellow below with heavy streaks. The song is a fast and nasal series: “Twee-chee-chee-chee-chee.”
