The common chaffinch (Fringilla coelebs), usually known simply as the chaffinch, is a common and widespread small passerine bird in the finch family. The male is brightly coloured with a blue-grey cap and rust-red underparts. The female is much duller in colouring but both sexes have two contrasting white wings-bars and white sides to the tail. The male bird has a strong voice and sings from exposed perches to attract a mate.
The chaffinch breeds in much of Europe, across Asia to Siberia and in northwest Africa. It prefers open woodland and often forages on the ground. The female builds a nest with a deep cup in the fork of a tree. The clutch is typically 4–5 eggs, which hatch in about 13 days. The chicks fledge in around 14 days but are fed by both adults for several weeks after leaving the nest. The chaffinch is a partial migrant; birds breeding in warmer regions are sedentary while those breeding in the colder northern areas of its range winter further south.
The chaffinch breeds in wooded areas where the July isotherm is between 12 and 30 °C (54 and 86 °F). The breeding range includes northwest Africa, most of Europe and extends eastwards across temperate Asia to the Angara River and the southern end of Lake Baikal in Siberia. There are also a number of distinctive subspecies on the Azores, the Canary Islands and the Madeira Islands in the Atlantic Ocean. The chaffinch was introduced from Britain into several of its overseas territories in the 19th century. In New Zealand the chaffinch has colonised both the North and South Islands and is now one of the most common passerine species. In South Africa a very small breeding colony in the suburbs of Constantia, Hout Bay and Camps Bay in Cape Town is the only remnant of another such introduction.
This bird is not migratory in the milder parts of its range, but vacates the colder regions in winter. This species forms loose flocks outside the breeding season, sometimes mixed with Bramblings. This bird occasionally strays to eastern North America, although some sightings may be escapees.
The main food of the chaffinch is seeds, but unlike most finches, the young are fed extensively on insects, and adults also eat insects in the breeding season. From Wikipedia, the free encyclopedia
