Experts have warned that bird feeders and baths should be regularly cleaned to prevent a disease which is being blamed for a drop in greenfinches.

Default Trichomoniasis in Finches - the American Goldfinch

Trichomoniasis in Finches - the American Goldfinch
CCWHC News

http://www.ccwhc.ca/goldfinch_article.php
excerpt from above:
Quote:
Trichomoniasis, the disease caused by this infectious organism, is a well documented illness affecting many bird species, but it is primarily diagnosed in pigeons and doves (also known as canker in these birds) and raptors (also know as frounce in these birds). Trichomoniasis has also been reported in various species of passerine birds, particularly sparrows and finches, and, since 2005, has emerged as a new cause of significant mortality in populations of greenfinch (Carduelis chloris) and chaffinch (Fringella coelebs) in the United Kingdom (UK), where it is known as trichomonosis (Duff et. al., 2007. The Veterinary Record. 161: 828). Similar to the pattern of disease occurrence associated with trichomoniasis in the UK, the seasonality of purple finch mortality in NS was late summer and early fall. This is unlike salmonellosis in songbirds which typically occurs in the winter. Although the history did not state it clearly, purple finch mortality in NS may have happened around bird feeders. If so, this would be another factor shared with the UK where mortality caused by trichomoniasis in finches is associated with the practice of bird feeding...

excerpt from above:Sanitation and Disease Control
When diseased birds are noted using your feeders, it's recommended to empty and thoroughly wash them with hot water and soap. Then apply a strong bleach solution (1 part javex to 9 parts water) for 15 minutes, and thoroughly rinse the disinfected feeder before putting it back out. Air-drying in full sun for a few hours before re-filling is useful as sunlight and desiccation may improve sterilization. Also, rake up fallen seed and droppings beneath feeders.

Because Trichomonas parasites require moist condtions to survive, bird baths and drinking containers should also be cleaned regularly.

If a number of diseased birds are in regular attendance at your feeders, feeding should be stopped to reduce close contact between sick and healthy individuals. I stopped feeding for three and a half weeks in late July-August 2008. The day after I resumed feeding (17 Aug.), two birds with infected eyes appeared, but they stayed only two days. I cleaned the feeders again and continued feeding with no sick birds seen until the two lethargic goldfinches on 10 September...
