What's a roost ring?

A detection of birds as they leave their morning roosting site. In this case they are taking off from the Alabama and Tombigbee Rivers

How often do you see the roost rings and do they look the same coming in as leaving the roost? Really cool!

They are most likely purple martins; they are visible in spots along rivers many summer mornings. More: http://www.jstor.org/stable/3783794?seq=1#page_scan_tab_contents …
