Subject: WNV in wintering Wisconsin bald eagles?

In early May, a posting to this listserve indicated that during this 
past winter WNV activity was detected in Wisconsin bald eagles. 
Based on our state WNV bird database and discussions with the 
laboratories in our state
known to be doing WNV testing on birds, there is no definitive 
evidence of eagles in WI having been infected with WNV in winter 
2002-3.  Based on tissue PCR results in our state database, there was 
1 WNV positive dead
bald eagle collected from Oconto County in October 2002.

A rehabilitator in WI had a great horned owl recovering from WNV 
relapse and die in January.  I can put anyone interested in contact 
with her as to what testing was used, if of interest.  I believe she 
also had two WNV positive bald eagles also come in in mid-winter, 
when temperatures were substantially below freezing.
