The Eurasian siskin, one of the smallest members of the finch family, makes its home in coniferous, mainly spruce woods, in both lowland country and mountains. It is found in central Europe, Scandinavia, Italy, southern France, Ireland and northern England, its range extending eastwards as far as western Siberia. The siskin is particularly fond of places alongside brooks, in which it loves to bathe.
In winter it leaves the woods to form flocks that roam in birch and alder groves, as well as in the vicinity of brooks and streams, where it feeds on birch and alder seeds. Its diet also includes the seeds of thistles. On occasion, it nips the buds of evergreens, and will sometimes feed on small berries. It is a very agile forager, clambering swiftly to the tips of branches and often hanging head downwards, similar to the antics of the tit family. Individuals from northern Europe frequently travel en masse to more southerly areas, often as far as the Mediterranean, returning to their breeding grounds at the end of March.
The female builds the nest at the tip of a branch, high up in a coniferous tree, generally more than twenty metres above the ground. It is made of slender twigs, bits of bark, lichen and moss and lined with feathers, down and hairs. The 3 to 5 eggs are incubated for 13 days by the hen alone, but she is assisted by the male in feeding the young, primarily with aphids and small caterpillars, in the beginning, The young birds leave the nest after two weeks and before long, usually in June, the siskin lays a second clutch.
