Eurasian Chaffinch

Overview

The Eurasian chaffinch is a common and widespread small passerine bird in the finch family, native to much of Europe and extending across the Palearctic to Siberia. It is classed as of Least Concern by the International Union for Conservation of Nature due to its large population and extensive range.

Identification

• The male features a blue-grey cap and rust-red underparts, while the female is duller in grey-brown tones.
• Both sexes possess two contrasting white wing bars and white sides to the tail.
• Adults measure approximately 14.5 cm in length with a weight ranging from 18 to 29 g.
• The male sings from exposed perches to attract a mate, exhibiting a strong voice.

Habitat

This species breeds in wooded areas where the July isotherm is between 12 and 30 °C, spanning most of Europe and temperate Asia to the Angara River and southern Lake Baikal in Siberia. Outside the breeding season, the bird forms flocks in open countryside. It is a partial migrant, with birds from colder northern regions moving further south for winter, while those in warmer areas remain sedentary.

Diet

Outside the breeding season, chaffinches forage for seeds and other plant material on the ground, often in large flocks. During the breeding season, they forage on trees for invertebrates, especially caterpillars, which are fed to their young.

Did you know?

The English name chaffinch derives from the Old English words for chaff and finch, as the birds were observed spending weeks picking through heaps of discarded chaff for grain after farmers threshed their crops.
