Origin, geographical range and distribution

The olivaceous siskin is distributed over Ecuador, Peru and Bolivia in South America. They typically occur between 1,200 and 3,000 metres in eastern side of Andes. The populations in higher altitudes descent to lower levels during winter.

Ecosystem and habitat

The olivaceous siskin species have moderate forest dependence. They normally occur in altitudes between 1200 to 3000 meters. The artificial ecosystems and habitats include heavily degraded forests.

The natural ecosystems and habitats of these species include tropical and subtropical moist montane forests and subtropical forest canopy.

Diet and feeding behavior

The diet of the olivaceous siskin species consists mainly of seeds. They forage for seeds in short plants, shrubs and bushes. They sometimes form feeding flocks.

Reproduction and breeding habits

The breeding season of these species is not known. Their reproduction and breeding habits have not been recorded.

Migration and movement patterns

The Spinus olivaceus species are non-migratory resident birds. The populations in higher altitudes descent to lower levels during winter.

Post breeding, the juveniles may disperse and establish in new locations within the range. Within their range they may make local movements for feeding and breeding.
