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 al. (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.

Greenfinch – 1894

Ligurinus chloris – A common resident.

Only too numerous in our grounds, where in the old ivy-covered walls there were always plenty of nests. We were no admirers of this bright-plumaged bird, because of his ceaseless attacks upon our garden seeds in the spring. All had to be netted over, or nothing would have escaped him. One pair of Greenfinches had the audacity to build their nest immediately above our seed bed, but they did not meet with the success they had, doubtless, anticipated.

Greenfinch – 1980s winter

Carduelis chloris – Llinos Werdd – Breeding resident and passage migrant The BTO winter atlas showed that Greenfinches were present in most 10km squares during the winters of 1981-82, 1982-82 and 1983-84. The darker the colour, the higher the relative total count for each 10km square.  The darkest blue represents over — birds. More about the Greenfinch […]
