Yesterday I found a HETH in my garden, struggling to get up, listing  
to one side.  Wondering if it had gone into the fence,I looked, but  
found no obvious injuries.  Guessing that it must be a central  
nervous system problem, I washed my hands later, and began to think  
about possible viruses.  Ornithologists:  what are symptoms of W.  
Nile virus.  Other viruses?  In the freezer now, should the bird be  
autopsied?
