I'm interested in knowing what would cause a Northern Mockingbird to have either 1) An infected eye or 2) Simply no eyes at all ? In the last week, I've come across two (2) different Northern Mockingbirds within two miles range of each other and both of them had no eyes. The entire eye area was black and looked dry, crusty, and simply "rotten" as if they caught a virus or had been infected. I did some research on it via Internet and came across some information, which I'll paste below, and perhaps this may be the same thing that has happened to these Northern Mockingbirds that I spotted. They were completely blind by the way because one of them I know for a fact kept bumping and flying into different objects.
"Mycoplasmosis is the most recently discovered disease in songbirds. It is being transmitted by direct contact, airborne droplets or dust. It causes conjunctivitis (infection of membranes of the eye). It has spread rapidly through the eastern population of house finches" (http://209.85.165.104/search?q=cache:J_upIH4V9voJ:rip.physics.unk.edu/nou/newsletter/199803.html+northern+mockingbird%2Beye+infection&hl=en&ct=clnk&cd=10&gl=us).
