Greenfinch - Chloris chloris
The European greenfinch, or just greenfinch (Chloris chloris), is a small passerine bird in the finch family Fringillidae.
This bird is widespread throughout Europe, north Africa and south west Asia. It is mainly resident, but some northernmost populations migrate further south. The greenfinch has also been introduced into both Australia and New Zealand. In Malta, it is considered a prestigious song bird, and it has been trapped for many years. It has been domesticated, and many Maltese people breed them.
Woodland edges, farmland hedges and gardens with relatively thick vegetation are favoured for breeding. It nests in trees or bushes, laying 3 to 6 Eggs.
This species can form large flocks outside the breeding season, sometimes mixing with other finches and buntings. They feed largely on seeds, but also take berries.
The protozoal parasite Trichomonas gallinae was known to infect pigeons and raptors but beginning in Britain in 2005, carcases of dead European greenfinches and common chaffinches were found to be infected with the parasite. The disease spread and in 2008 infected carcases 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 chaffinches as large numbers of the birds breed in northern Europe and winter in Britain. In Britain the number of infected carcases recovered each year declined after a peak in 2006. There was a reduction in the number of greenfinches from around 4.3 million to around 2.8 million but no significant decline in the overall number of chaffinches. A similar pattern occurred in Finland where, after the arrival of the disease in 2008, there was a reduction in the number of greenfinches but only a small change in the number of chaffinches.
Greenfinch populations declined during the late 1970s and early 1980s, but increased dramatically during the 1990s. A recent decline in numbers has been linked to an outbreak of trichomonosis, a parasite-induced disease which prevents the birds from feeding properly.
