Description
The adult male olivaceous siskin has a black face, head, nape, throat and upper breast. It has a narrow collar of yellow and the rest of the upper parts, apart from the yellow rump, are olive green streaked with black. The greater wing coverts have a yellow edge, and this, with the yellow bases to the flight feathers, form a yellow panel when the bird is in flight. Underparts are yellowish-green with a dull yellow lower breast and belly. The tail is brownish-black, with the bases of the outer feathers yellow. The head of the adult female lacks the black of the male, and it and the upper parts are mainly yellowish-olive. The yellow rump, wings and tail are similar to those of the male. Beaks in both sexes are grey and legs are pinkish-brown or brown. Juvenile coloration is similar to the female's but is generally more brownish with the yellow parts being duller, buff or streaked with brown.

Feeding Habits
Olivaceous Siskin primarily consumes seeds from various low-growing plants as well as bushes and trees. Foraging typically occurs in shrubs and at canopy levels, actively moving in pairs or small groups, and forming larger flocks non-breeding season. They are noisy, restless, and rarely feed on the ground or away from forests.
Habitat
The habitat of olivaceous Siskin typically encompasses montane and subtropical forests, specifically within the canopy, forest edges, and clearings that are characteristic of upper slopes. These environments offer the general environmental conditions preferred by the species, spanning across broader geographical regions with such forested ecosystems.

Behavior
The olivaceous siskin is an active, social species, usually seen in pairs or small groups, but sometimes forms larger flocks, especially in winter. It feeds on seeds, mainly on the ground and in low shrubs, but sometimes higher in trees. Its behaviour and appearance is generally similar to that of the hooded siskin but they differ in range and habitat choice.
Distribution Area
This is a bird of the eastern side of the tropical high Andes. It ranges from northern Peru to La Paz and Cochabamba in Bolivia and to southeastern Ecuador, and has also been observed east of the Andes near Santa Cruz de la Sierra in Bolivia. Typically it is found between 1,200 and 3,000 metres (3,900 and 9,800 ft) above sea level, in forest clearings and forest verges.
Species Status
S. olivaceus has a wide range and is a fairly common species. The population trend may be downwards, but not at such a rate as to warrant undue concern, so the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".
