This female House Finch with eye disease was seen at my feeder with a pair of House Finches. The other two finches showed no sign of eye disease. The affected finch seemed to be blind in this eye and was flying erratically. A hawk (Sharp-shinned or Coopers) flew through the yard and all of the birds left. I never saw this sick finch again at my feeders. I took down my feeder, disinfected in and kept it down for several days. I replaced the feeder after only seeing the healthy pair of House Finches returning to my feeders. Since then, I have checked every House Finch at my feeders carefully to see if any of them show any signs of eye disease and so far, they have not.
