Common resident, but not universally numerous. Scarcer as a breeder in treeless country. Abundant in winter, especially on coastal farms. regular spring migrant at Skokholm, which it also visits in winter.

Friday, August 24, 2012 at 9:24PM Due to changes in agricultural practices, the greenfinch is becoming less common in farmland. Parks and gardens with tall trees are now the preferred habitat for breeding, especially if evergreen trees are present. The prevalence of such trees in towns and villages may be encouraging the birds to move there.
It was estimated that 4–5,000 pairs were nesting in the county during the 1984-88 survey. The distribution found during the 2003-07 survey shows an increase of 47% in the number of squares recorded, with an in–filling within the existing widespread range rather than any expansion. The 1984-88 survey estimated the density at 15 – 20 pairs per tetrad, if that estimate is still true then the increase in occupied squares would indicate an increase in the breeding population to c. 6–7,500 pairs. The BBS assessment of a 27% increase in the population between 1994 and 2002 would broadly agree with this.
A cautionary note should be added at this time, in some gardens birds are suffering from an infectious disease which can be fatal. How this may affect future breeding populations we will have to see.

A common resident/according to Mathew (1894) and Lockley et ai. (1949), the Greenfinch currently breeds across Pembrokeshire (see map) being found especially around gardens and where there are scattered trees. At an estimated 15 to 20 pairs per tetrad the county total would be 4,000-5,000 pairs.
Small numbers are recorded passing through coastal areas between 7 March and 12 June, and again from 27 September to 6 December. They stop off at the islands, including the remoter isles such as the Smalls, and one ringed at Skokholm was later recovered in County Wexford, Ireland.
They flock in winter at good food sources, such as seeded turnips and flax, are increasingly frequent at bird-tables and form communal roosts in dense shrubbery, for instance in blackthorn at the Gann.
