Description

This is a small green-and-yellow finch. According to some sources, it is the smallest species of finch on average, although others give this title to the lesser goldfinch. The total length can range from 9.5 to 11 cm (3.7 to 4.3 in). A weight of 11.5 g (0.41 oz) may be at the high end. Few standard measurements are known, although the bill has been recorded at 1.1 cm (0.43 in) and the wing chord length is reportedly around 6.4 cm (2.5 in). The Andean siskin has deep green upperparts with black and yellow coloration on the wings and tail. The adult male has a distinctive black cap. Female lacks this cap and is generally a duller olive color, with white from the belly to the undertail-coverts. The female differs from female yellow-bellied siskin in being paler and brighter, also by lacking the olive throat and yellow undertail-coverts of that species. Female hooded siskins are also similar but the Andean has distinctive white undertail-coverts and more olive-green rather than gray color. The Andean siskin race S. s. nigricauda is generally duller or darker green on upperparts than the nominate, in this subspecies the underparts are dull green and lacking any trace of yellow. The tail is all black and the wings lack greenish-yellow tips to the coverts but the race does retain bright yellow bases to the inner primaries and secondaries. The race S. s. capitanea is similar but the underparts are generally paler olive without any of the dark olive centers to the feathers, it also has yellow on sides of the base of the tail and on the tips of the median and greater coverts. The Andean siskin's call is a typical goldfinch-like tswee or similar variation, frequently given in flight. The song, also goldfinch-like, is a lively rambling series of notes, high pitched and interspersed with rolling trills.
Feeding Habits
Andean Siskin primarily eats plant seeds, especially Espeletia, and flowers. They forage in low vegetation or on the ground, and perch in treetops. Andean Siskin feeds in pairs or small groups, sometimes joining mixed flocks with other finches during non-breeding season.
Habitat
Andean Siskin typically inhabit areas with low bushes and scrub at the edges of open cloudforest or elfin forest. These birds are also found in páramo regions and open hillsides that have scattered trees, thickets, and bushes, or near the edges of cultivated lands.
Dite type
Granivorous
