According to:
http://www.cdc.gov/od/oc/media/wncount.htm

1852 reported cases so far this year and 89 deaths (4.8%)

Compared to the flu which peaked with 1750 case IN JUST ONE WEEK last
February:

"Pneumonia and Influenza (P&I) Mortality: During week 20, the percentage
of all deaths due to pneumonia and influenza as reported by the vital
statistics offices of 122 U.S. cities was 6.5%. This percentage is below
the epidemic threshold of 7.5% for week 20."

One wonders, since only dead birds are being tested, how many birds
get West Nile, suffer mild flu -like symptoms and recover...

A child who becomes acquainted with the birds about him
hears every sound and puzzles out its meaning with a cleverness
that amazes those with ears who hear not.
