Diseased Bird: Avian Pox or Conjunctivitus of House Finch

This House Finch dominated the window feeder, but always looking at me through his right eye, only. I reported his right foot, with its swollen toes, and then on this video caught a glimpse of his left eye, and noticed the swollen ring around it. This was on 12/8/23.The House Finch continued to show up to the window feeder, and by 12/11/23 his left eye was swollen shut in every frame I caught. My heart broken, I emptied and cleaned all the feeders, including the hummingbird feeder where he would sometimes alight, and will wait a few weeks until the birds disperse. As of 12/12/23, my Merlin app still registered many bird calls in my yard, including the House Finches, although the feeders were gone and I had washed and turned over the birdbath.
