Taxonomy
The Eurasian chaffinch was described by the Swedish naturalist Carl Linnaeus in 1758 in the 10th edition of his Systema Naturae under its current binomial name.[2] Fringilla is the Latin word for finch, while caelebs means unmarried or single. Linnaeus remarked that during the Swedish winter, only the female birds migrated south through Belgium to Italy.[2][3]
The English name comes from the

Subspecies
A number of subspecies of the Eurasian chaffinch have been described, based principally on the differences in the pattern and colour of the adult male plumage.

Description
The Eurasian chaffinch is about 14.5 cm (5.7 in) long, with a wingspan of 24.5–28.5 cm (9.6–11.2 in) and a weight of 18–29 g (0.63–1.02 oz).
After the autumn moult, the tips of the new feathers have a buff fringe that adds a brown cast to the coloured plumage. The ends of the feathers wear away over the winter so that by the spring breeding season the underlying brighter colours are displayed.[17][18] The eyes have dark brown irises and the legs are grey-brown. In winter the bill is a pale grey and slightly darker along the upper ridge or culmen, but in spring the bill becomes bluish-grey with a small black tip.[19]
The male of the subspecies resident in the British Isles (F. c. gengleri) closely resembles the nominate subspecies, but has a slightly darker mantle and underparts.[20]
The adult female is much duller in appearance than the male. The head and most of the upperparts are shades of grey-brown. The underparts are paler. The lower back and rump are a dull olive green. The wings and tail are similar to those of the male. The juvenile resembles the female.[21]
Voice
Males typically sing two or three different song types, and there are regional dialects also.[22][23]
The acquisition by the young Eurasian chaffinch of its song was the subject of an influential study by British ethologist William Thorpe. Thorpe determined that if the young common chaffinch is not exposed to the adult male's song during a certain critical period after hatching, it will never properly learn the song. He also found that in adult Eurasian chaffinches, castration eliminates the song, but injection of testosterone induces such birds to sing even in November, when they are normally silent.[24][25]
Distribution and habitat
The Eurasian chaffinch breeds in wooded areas where the July
This bird is not migratory in the milder parts of its range, but vacates the colder regions in winter. It forms loose flocks outside the breeding season, sometimes mixed with bramblings. It occasionally strays to eastern North America, although some sightings may be escapees.
Behaviour
Breeding
Eurasian chaffinches first breed when they are 1 year old. They are mainly monogamous and the pair-bond for residential subspecies such as gengleri sometimes persists from one year to the next.[30] The date for breeding is dependent on the spring temperature and is earlier in southwest Europe and later in the northeast. In Great Britain, most clutches are laid between late April and the middle of June. A male attracts a female to his territory through song.[31]
Nests are built entirely by the female and are usually located in the fork of a bush or a tree several metres above the ground.
In a study carried out in Britain using ring-recovery data, the survival rate for juveniles in their first year was 53 per cent, and the adult annual survival rate was 59 per cent.[36] From these figures the typical lifespan is only 3 years,[37] but the maximum age recorded is 15 years and 6 months for a bird in Switzerland.[38]
Feeding
Outside the breeding season, Eurasian chaffinches mainly eat seeds and other plant material that they find on the ground. They often forage in open country in large flocks. Common chaffinches seldom take food directly from plants and only very rarely use their feet for handling food.[39] During the breeding season, their diet switches to invertebrates, especially defoliating caterpillars. They forage in trees and also occasionally make short sallies to catch insects in the air.[39] The young are entirely fed with invertebrates which include caterpillars, aphids, earwigs, spiders and grubs (the larvae of beetles).[39]
Predators and parasites
The eggs and nestlings of the Eurasian chaffinch are predated by crows, Eurasian red and eastern grey squirrels, domestic cats and probably also by stoats and weasels. Clutches begun later in the spring suffer less predation, an effect that is believed to be due to the increased vegetation making nests more difficult to find.[40] Unlike the case for the closely related brambling, the common chaffinch is not parasitised by the common cuckoo.[41]
The protozoal parasite Trichomonas gallinae was known to infect pigeons and raptors, but beginning in Great Britain in 2005, carcasses of dead European greenfinches and common chaffinches were found to be infected with the parasite.[42] The disease spread and in 2008, infected carcasses were found in Norway, Sweden and Finland and a year later in Germany. The spread of the disease is believed to have been mediated by Eurasian chaffinches, as large numbers of the birds breed in northern Europe and winter in Great Britain.[43] In Great Britain, the number of infected carcasses recovered each year declined after a peak in 2006. There was a reduction in the number of European greenfinches but no significant decline in the overall number of common chaffinches.[44] A similar pattern occurred in Finland where, after the arrival of the disease in 2008, there was a reduction in the number of European greenfinches, but only a small change in the number of Eurasian chaffinches.[45]
Eurasian chaffinches can develop tumors on their feet and legs caused by the Fringilla coelebs papillomavirus.[46][47] The size of the papillomas range from a small nodule on a digit to a large growth involving both the foot and the leg. The disease is uncommon: in a 1973 study undertaken in the Netherlands, of around 25,000 common chaffinches screened, only 330 bore papillomas.[46]
Status
The Eurasian chaffinch has an extensive range, estimated at 7 million square kilometres (3.7 million square miles) and a large population including an estimated 130–240 million breeding pairs in Europe. Allowing for the birds breeding in Asia, the total population lies between 530 and 1,400 million individuals. There is no evidence of any serious overall decline in numbers, so the species is classified by the
Relationship to humans
The Eurasian chaffinch was once popular as a caged songbird and large numbers of wild birds were trapped and sold.[49] At the end of the 19th century, trapping even depleted the number of birds in London parks.[50] In 1882, the English publisher Samuel Orchart Beeton issued a guide on the care of caged birds and included the recommendation: "To parents and guardians plagued with a morose and sulky boy, my advice is, buy him a chaffinch."[49] Competitions were held where bets were placed on which caged common chaffinch would repeat its song the greatest number of times. The birds were sometimes blinded with a hot needle in the belief that this encouraged them to sing.[51] This practice is the subject of the poem The Blinded Bird by the English author Thomas Hardy, which contrasts the cruelty involved in blinding the birds with their zestful song.[52] In Great Britain, the practice of keeping Eurasian chaffinches as pets declined after the trapping of wild birds was outlawed by the Wild Birds Protection Acts of 1880 to 1896.[52][53]
The Eurasian chaffinch is still a popular pet bird in some European countries. In Belgium, the traditional sport of
