I found this on the Virginia bird listserv.

Preliminary summary statistics for the recent Rusty Blackbird Blitz can be found at 
http://nationalzoo.si.edu/ConservationAndScience/MigratoryBirds/Research//Rusty_Blackbird/blitz_results.cfm. 
The site features some nice summary graphics, tables and interactive maps.  Apparently, further analyses are being conducted and will be reported when complete.  

Interesting results for Maryland.
