This pair of greenfinches were part of what seemed a plentiful population during our visit to RSPB Fairburn Ings, attracted by the splendid feeders there.
But this is not the case everywhere. The British Trust for Ornithology reports that “Until 2005, greenfinches were one of the most common birds at our garden feeders. However, hit by the disease finch trichomonosis, they are now a rarity in many gardens and their population has declined by about 35 per cent.” BTO makes the point that trichomonosis “can be spread between birds at garden feeding stations so it is very important to regularly clean feeders and bird tables”. Self and others please note.

Thanks for the information. I love those little guys! We do clean ours often.
