I took photos of my dad’s feeder last weekend, during a visit. It wasn’t until I was looking at the photos later that night that I noticed that his house finches and Pine Siskin’s had eye issues. I counted a total of 5 birds with the infections at all diferent stages. 1 house finch and 4 Pine Siskins. I advised my father and provided him with info.
Yes, this is very likely a case of mycoplasmal conjunctivitis. But, the bird pictured is a Purple Finch, not a House Finch. Note the front-heavy/large-headed structure, red coloring in the wings and short, notched tail.
