Chimney Swift Roost

Shelia was driving to work yesterday after dropping me off and observed many Chimney Swifts exiting a smokestack in downtown Austin. This morning we went to the location and marked the GPS location for the Kyles. Shelia sent me this map with the chimney pointed out.
The birds were exiting the stack within 5 minutes of sunrise and we observed them for approx. 5 minutes without any slacking. So cool!
