I’m suddenly seeing a lot of House Finches with red, swollen, and weepy eyes. What’s wrong with them?
A. The sick House Finches are probably afflicted with Mycoplasmal conjunctivitis, otherwise known as House Finch Eye Disease. In early fall, the prevalence of this infection increases dramatically, and bird watchers may start to find many more sick birds at their feeders. To read more about this disease and to learn about the citizen science project that attempts to track and understand it, please visit the House Finch Disease Survey.
