From November through April Project FeederWatch participants can report observations of eye disease as part of their regular counts. I'm not aware of anyone else collecting data on eye disease.

Since you have such a significant outbreak, you should probably take down the feeders the goldfinches are using for a couple of weeks to encourage them to disperse and to assure disease isn't being spread at your feeders. Then if sick birds return, avoid using feeders with ports that birds put their heads into.

You can learn more about eye disease on the Project FeederWatch website.

Subject: [cayugabirds-l] Goldfinch eye disease
 
A number of goldfinch at my feeder in W. Danby have eye disease. They’re so disoriented they often land on me as a perch trying to find the feeders, which I scrub each week with warm water and a touch of bleach. Is the LabofO still keeping tabs on this? If so where to report my data. Other thoughts? It seems fatal since I’ve found three dead in past 2 months with the ‘glue eye’ diagnostic. I gather their deaths are probably for lack of feeding acumen due to blindness more than anything. (BTW I only get the list digest here so include me in any response.) Thx, Peter
