There are 2 good websites related to House Finch conjunctivitis--
http://www.ornith.cornell.edu/Citizen_Science/HOFIdisease.htm
http://members.aol.com/FinchMG/Home.htm

The second is a bit more informative than the first. They contain
information on what the disease looks like, what to do, why HOFI seem to be
particularly susceptible, etc.
