オリーブヒワ Spinus olivaceus

Small, yellow finch found in cloud forest along the east slope of the Andes. Note yellow patches in wings and tail. Male has a black hood. Difficult to separate from Hooded Siskin except by range and habitat. Olivaceous Siskin is generally found at lower elevations and prefers taller, more humid forest. Male may appear slightly more golden than male Hooded Siskin, but this is hard to judge. Female is always yellow below, whereas most (but not all) female Hooded Siskins in the area of overlap are grayish below. Not all birds can be safely identified.
