I think we had a discussion on TN-Birds last year on using radar to see purple 
martins come off roost.  Anyway, I've included a couple links of interest and 
notes.

The Nashville martin roost can be seen fairly clearly as a donut expanding out 
from eastern Davidson Co.  The radar station that shows it best is from 
Huntsville, AL (the Nashville one is too close to the roost to show it 
effectively).  The radar track only shows base reflectivity for the last hour 
or so, meaning the birds are only visible on the radar first thing in the 
morning with the current radar.

This link is from Birmingham, AL.  There is evidence of the Huntsville area 
(Wheeler NWR?) martin roost and a LARGE roost southeast of Demopolis, AL (due 
south of Tuscaloosa).  This was a large, very well defined expanding donut 
shape this morning.

You can change around to different radars using the arrow/toggle buttons near 
the top left of the page.  Enjoy!
