- Since 2005, Greenfinches in Ireland and the UK have been increasingly impacted by the Trichomonas parasite. It causes disease in the back of the throat and mouth, which prevents the bird from feeding. Affected birds often appear fluffed up and lethargic, and the disease seems to be almost always fatal. See here for more info.
- If you see a Greenfinch, or other species, that looks sick you should take in your feeders for a week or so, and clean them thoroughly with a mild bleach solution. See here for more info.
- The increasing popularity of garden feeding has been credited with an expansion in their range further north in Scandinavia.
- Back in Victorian times they were widely trapped and kept in captivity, along with other finch species.
- Other local names for Greenfinch inlcude Green Linnet and Green Grosbeak.
- Historically they would have been a bird of woodland and forest edges, but in recent decades they've expanded to take advantage of food and habitat in hedgerows, towns and gardens.
