Figure 2. A) Native breeding range of owl species showing high
death rates (>90%), B) no deaths, C) low death rates (<20%), and
D) the combined distributions of species in the high and no mortality
groups with that of Saint Louis encephalitis (SLE) in the United States
and Canada. The distribution maps have been redrawn based on maps previously
published (16–19). The distribution of SLE
is based on human cases reported in the United States and in Canada from
1964 to 2000 (25,26). Only states and provinces
that had >1 case per 100,000 capita during this period were included.
