Whatever is going on is SPECIES related. More than 350 miles away in Louisiana.

Maybe not.  There are starlings along with the Red Wing Blackbirds this time. 

On Monday, (click title to entry - thank you) state biologists were gathering up some of the approximately 500 blackbirds and starlings that lay dead along Louisiana Route 1 near Pointe Coupee Central High School for testing.... 

It is really odd this is happening to Red Wing Blackbirds in the South though.  There has to be a common denominator. 

This isn't just about birds, there was a fish kill within a week of the bird deaths in Arkansas. 

Temperatures? 

Maybe. 

There was a low pressure system over Shrevesport. Louisiana on January 1, 2010.

There was a rapid change in temperature and a fall in air pressure which makes sense, but, nothing that is very unusual for the area or the time of year.  Again, the Red Winged Blackbird is a hearty species that lives across the entire continent of North America in all weather extremes. 

The picture is NOT clear.
