Crow deaths associated with West Nile virus (WNV) infection and maximum and mean temperatures for Poughkeepsie, New York, USA (December 1, 2004–March 31, 2005). Roost area was checked for crow carcasses at least every 48 hours after February 10, 2005. Temperature data were obtained from National Oceanic and Atmospheric Administration, Silver Spring, Maryland, USA. All 98 crow carcasses were tested for WNV by reverse transcription–PCR (RT-PCR) (2), VecTest, and Rapid Analyte Measurement Platform (3,4). Twelve were positive by all 3 tests; 1 crow collected on March 7, 2005, was positive by RT-PCR only.
