Greenfinch
Introduction
This stocky finch can be found throughout in Britain & Ireland at all times of the year, except on the highest peaks.
The Greenfinch has a twittering song, which features a distinct drawn-out wheeze. It is a bold species and can enter into squabbles with other birds at garden feeders. It is also found in open woodland and farmland. Males have distinctive green plumage, with yellow in the wing and tail. Females and juveniles are duller.
The Greenfinch has undergone a major population decline in the UK since the mid-2000s, due to the disease Trichomonosis. It was added to the UK Red List in 2021. In the winter, Greenfinch numbers are supplemented by birds migrating from Fennoscandia.

Status and Trends
Conservation Status
Population Change
Greenfinch abundance fluctuated somewhat up to the mid 1990s, but there was little change in either survival or breeding performance during this period (Siriwardena et al. 1998b, 2000b). More recent CBC/BBS data indicate population increases widely across the UK, followed by a sudden sharp fall induced by a widespread and severe outbreak of trichomonosis disease. Although Greenfinch is currently still green listed in the UK, based on the trend at the time of the last review (Eaton et al. 2015), the current decline would raise red listing and caused it to be rated as 'Endangered' in a recent assessment of UK species which followed IUCN criteria and categories (Stanbury et al. 2017).
The BBS map of change in relative density between 1994-96 and 2007-09 indicates that increases over that period, strongest in East Anglia and in western Britain, contrasted with decreases in eastern Northern Ireland, northeastern Scotland and central southern England. The subsequent, disease-related decrease is ongoing in all parts of the UK. Numbers across Europe have been broadly stable since 1980, with early increases being followed by a decline starting in the 1990s (PECBMS: PECBMS 2020a>).
Distribution
Greenfinches are widely distributed in winter and the breeding season, perhaps showing especially strong associations with villages and towns across Britain & Ireland. Like the Goldfinch, its only significant range gaps are in the higher parts of northern Scotland. Highest densities are found on lower ground, mainly in south and southeast England, eastern Scotland and in pockets throughout Ireland.

Distribution Change
Since the 1981–84 Winter Atlas the range has increased by 18%, involving infilling in western Ireland and parts of Wales and northern England, and a more continuous expansion around the coastal-upland fringe in northwest Scotland.

Causes of Change and Solutions
Causes of change
The rapid decline since 2005 has been caused by a severe outbreak of trichomonosis.
Further information on causes of change
The sudden sharp fall that began in 2005 was induced by a widespread and severe outbreak of trichomonosis, a disease which affects the upper digestive tract (Robinson et al. 2010b, Lawson et al. 2012b, 2018). Integrated population modelling shows that changes in survival have indeed been the strongest contributor to annual population change (Robinson et al. 2014).
Productivity data show minor decreases in clutch and brood sizes, but no change in the number of fledglings per breeding attempt. The trend towards earlier laying may be explained by recent climate change (Crick & Sparks 1999).
Information about conservation actions
The recent population downturn has been directly linked to the spread of trichomonosis (Lawson et al. 2014), and hence hygiene precautions are important in gardens where food and water is being provided, and stopping feeding should be considered if birds with the disease are observed see here. The rate of decline has not yet slowed down and it is unclear whether improved garden hygiene will halt the decline.
As for Chaffinch, there have been no conservation concerns about this species until recently; hence there are no specific conservation actions relating to this species. However, assuming some birds are resistant to trichomonosis, actions and policies aimed at helping other farmland species are also likely to benefit Geenfinches and may enable numbers to recover in the future. These would include actions aimed at increasing food availability over winter (e.g. overwinter stubbles, wild bird seed or cover mixtures, set-aside, buffer strips or uncultivated margins) and those aimed at improving breeding habitat and food availability during the breeding season (e.g. management of hedgerows and reducing pesticide and herbicide use).
