Looking at the current MMWR totals for West Nile:

2008............686..................666
2009............332..................280

Are more bats consuming mosquitoes?
"Each year, tree bats are encountered at latitudes above 38? in North America during the summer but are mostly absent during the winter. Despite this seasonal occurrence and many observations suggesting migratory activity (e.g., landing on ships at sea and on remote islands), the details of their seasonal movements are poorly understood." http://www.fort.usgs.gov/resources/research_briefs/bat_isotopes.asp
?The common Vampire bat is native from northern Mexico southward to Chile and central Argentina and Uruguay as well as the island of Trinidad. It is found in both arid and humid regions of the South American tropics and subtropics.? http://www.conservationcentre.org/scase7.html
